NAD vs Niacin vs Niacinamide: Vitamin B3 Differences Decoded

Written by Jinfiniti Science on December 21, 2024. Posted in NAD+, NAD+ Precursors, Niacin, Nicotinamide, Vitamin B. No Comments on NAD vs Niacin vs Niacinamide: Vitamin B3 Differences Decoded

The vitamin B3 on your supplement label hides a deeper truth.

What appears as a single nutrient actually represents a family of compounds—each following its own path through your cellular machinery.

Understanding the difference between NAD, niacin, niacinamide, and nicotinamide isn’t just biochemistry—it’s the key to unlocking specific health benefits while avoiding unwanted effects.

Let’s decode what your supplement label doesn’t tell you about the forms of vitamin B3.

Vitamin B3: A Short History

In 1937, Conrad Elvehjem made an accidental discovery that would reshape our understanding of human health. While studying black tongue disease in dogs, he isolated a compound that not only cured the canine condition but also proved to be the key to solving pellagra—a devastating human disease that had claimed thousands of lives across the American South.

That compound was niacin, but it was just the beginning. What started as a single vitamin has evolved into a complex family of molecules. Modern longevity researchers have transformed B3 from a simple nutritional supplement into a cornerstone of aging research, with different forms of the vitamin showing distinct effects on cellular health, energy production, and DNA repair.

Is NAD More Than Just Another B3?

NAD or nicotinamide adenine dinucleotide stands apart from other B3 vitamins—it’s not a form of B3, but rather a critical coenzyme your cells use as currency in energy transactions. We can think of NAD as cellular currency: every metabolic purchase your cells make requires NAD+, from breaking down glucose¹ to repairing damaged DNA².

A single red capsule sits apart from a large pile of various colorful pills and supplements.

But here’s where it gets interesting: despite NAD+’s fundamental role, you can’t simply swallow it as a supplement. The molecule is too large and unstable to survive digestion³. Your body must build its NAD+ supply from smaller B3 building blocks—each with its own efficiency rating in the conversion process.

The connection between NAD+ and aging emerged when scientists discovered that our NAD+ levels plummet as we get older. This decline correlates with many hallmarks of aging: decreased energy production, impaired DNA repair, and reduced cellular resilience. Restoring NAD+ levels has become a central focus in longevity research.

Let’s break down the family of B3 compounds and their relationship to NAD+:

B3 Form	Conversion to NAD+	Key Benefits	Sources
Niacin (Nicotinic Acid)	3-step process, moderate efficiency	Cardiovascular health, cholesterol management	Food sources, immediate-release supplements
Niacinamide (Nicotinamide)	2-step process, good efficiency	Skin health, joint function	Supplements, fortified foods, skincare products
Nicotinamide Riboside (NR)	2-step process, high efficiency	NAD+ boosting, cellular energy	Specialized supplements

What is Niacin? The Original B3

Niacin—known chemically as nicotinic acid—remains the most thoroughly studied form of vitamin B3. Its simple molecular structure belies its power: a six-member ring with a carboxylic acid group that gives this compound its distinctive properties.

You’ll find niacin throughout the natural world. It’s abundant in meat, fish, and nuts, with mushrooms and avocados providing substantial plant-based sources. Unlike other B3 forms, it announces its presence in your body with an unmistakable sensation.

The infamous “niacin flush” stands as both blessing and curse. Within 30 minutes of taking higher doses, your skin turns red and warm—a temporary but often intense experience that feels like a sunburn. This flush isn’t dangerous—it’s actually a sign of niacin expanding your blood vessels, the same mechanism behind its cardiovascular benefits⁴.

Beyond circulation, niacin shows remarkable effects on blood lipids that other B3 forms can’t match. It’s the only B3 variant proven to both lower harmful LDL cholesterol and raise beneficial HDL cholesterol⁵. This unique property has kept niacin relevant in an era of more exotic B3 derivatives.

Niacinamide vs Nicotinamide

The supplement industry’s cleverest marketing trick lies in making two identical molecules seem different. Niacinamide and nicotinamide are perfect chemical twins—same structure, same effects, same molecule.

This dual naming stems from historical quirks in scientific nomenclature. While researchers prefer “nicotinamide,” the cosmetics industry adopted “niacinamide”—creating an illusion of distinction that persists in marketing materials and product labels.

The truth? Both names describe a modified form of B3 where the carboxylic acid group of niacin has been replaced with an amide group. This small change eliminates the flush reaction while opening new therapeutic doors. Your skin cells particularly love this form of B3—they readily absorb it and use it to repair UV damage, reduce inflammation, and regulate oil production⁶.

The benefits extend beyond skincare. Whether labeled niacinamide or nicotinamide, this form of B3 supports joint health, aids cellular repair, and helps maintain DNA integrity—all without the circulation-related effects of standard niacin.

Nicotinamide Riboside and Nicotinamide Mononucleotide

A common misconception clouds the NAD+ precursor landscape: while Nicotinamide Riboside (NR) belongs to the B3 family, Nicotinamide Mononucleotide (NMN) does not. NMN represents the next step in the NAD+ production pathway—a larger, more complex molecule that sits between B3 vitamins and NAD+ itself.

When comparing NMN and NR, both compounds share a singular purpose: boosting NAD+ levels. But they take different routes to this destination. NR enters cells directly through specialized transporters, while NMN must either convert to NR before absorption or use recently discovered transport mechanisms. This distinction has sparked intense debate in the research community about their relative effectiveness.

The scientific evidence paints a nuanced picture. Clinical trials show both molecules can increase NAD+ levels, with participants reporting improved energy, better sleep quality, and enhanced exercise performance. Studies on safety and side effects for both compounds are encouraging—NR has demonstrated a strong safety profile across multiple long-term trials⁷, while NMN has shown excellent tolerability in human studies⁸, with research continuing to expand our understanding of both molecules.

Recent research has uncovered tissue-specific preferences for these molecules⁹. Some organs appear to utilize NR more efficiently, while others show stronger responses to NMN. This finding suggests that the “best” NAD+ precursor might depend on your specific health goals and target tissues.

Choosing a B3 Supplement

Selecting the right B3 supplement demands a strategic approach based on your health objectives and biochemical needs. The form you choose defines not just the benefits you’ll receive, but also how your body will respond to the supplement.

Your supplementation strategy should align with specific health goals:

For cardiovascular health and lipid management: Standard niacin remains the gold standard, though the flush reaction requires careful dose titration. Start with 100mg and gradually increase to assess tolerance.
For skin health and inflammation: Choose products containing niacinamide (nicotinamide), particularly in concentrations between 2-10% for topical applications. Look for formulations free of potential irritants.
For cellular energy and longevity support: NAD+ precursors offer the most direct path. Modern research points to combination approaches that support multiple aspects of cellular energy production.

When evaluating NAD+ precursor supplements, look beyond basic formulations. The most effective products combine precursors with synergistic compounds that support cellular energy metabolism—a strategy backed by emerging research.

The Vitality ↑® NAD+ Booster exemplifies this advanced approach. Combining NAD precursors NMN and nicotinamide with cellular energy enhancers Creatine monohydrate and D-Ribose, our NAD precursor powder supports both NAD production and overall energy metabolism. This clinically-validated formulation addresses the complex nature of cellular energy production.

Before starting any B3 supplementation:

Consult healthcare providers if you take medications, particularly diabetes drugs or statins
Choose morning supplementation for most forms, except when using niacin (which some prefer at night to sleep through the flush)
Store your supplements in cool, dry places—NAD precursors particularly benefit from proper storage
Look for third-party testing certification and clear ingredient labeling
Consider cost per effective dose rather than just price per bottle

The right B3 supplement can transform your cellular health—but only when chosen with purpose and used with understanding. Your investment in B3 supplementation should match your health goals, backed by science and quality manufacturing.

What Are Sirtuins and What Is Their Role in Aging?

Written by Jinfiniti Science on December 20, 2024. Posted in NAD+, NAD+ Precursors, Premature Aging. No Comments on What Are Sirtuins and What Is Their Role in Aging?

Aging is inevitable, influenced by genetics, lifestyle, and the environment. At the cellular level, changes like DNA damage, reduced energy production, and rising inflammation drive aging. The good news is, science has uncovered some fascinating ways to understand and possibly slow down the process.

Among the most exciting discoveries involves sirtuins, a family of proteins that help how our bodies handle aging. They regulate metabolism, protect DNA, and manage oxidative stress to keep our cells functioning properly.

What makes sirtuins particularly intriguing is their connection to NAD+, a molecule that’s critical for their function. Unfortunately, NAD+ levels drop as we get older, limiting sirtuins’ ability to protect our cells from damage.

However, research shows that boosting NAD+ levels through supplements, exercise, and other strategies can reactivate sirtuins to help combat age-related decline. This makes understanding sirtuins an important piece in the puzzle of aging and optimizing health.

In this article, we’ll discuss:

Why NAD+ is a cofactor for sirtuins and how boosting NAD+ levels can increase sirtuin activity and combat aging.

The fascinating role of sirtuins in regulating metabolism, DNA repair, and cellular stress, and how they contribute to longevity.

The science behind caloric restriction and how it activates sirtuins to improve lifespan and overall health.

What are Sirtuins?

An image of a cellular regulator of the body

Sirtuins are a family of seven evolutionarily conserved proteins (SIRT1-7) that act as cellular regulators, earning them the nickname “guardians of the genome” for their multifaceted roles in metabolism, gene expression, and cellular health. They depend on a molecule called nicotinamide adenine dinucleotide (NAD+) to do their job and carry out molecular functions.

Specifically, sirtuins belong to a family of NAD+-dependent enzymes called histone deacetylases,¹ which modify both DNA-packaging proteins and many other cellular proteins. Through their deacetylation activity – removing acetyl groups – sirtuins function as molecular switches that control gene expression, metabolism, stress responses, and cellular aging by responding to the cell’s energy state.

The discovery of sirtuins is rooted in the study of aging. Scientists first identified a sirtuin protein in yeast, called Sir2,² while investigating the genetic factors that influence lifespan. They found that under conditions of caloric restriction, Sir2 activity increased, leading to a 30%–40% increase in lifespan.³ This discovery sparked interest in sirtuins and their potential role in longevity.

Sirtuins act as important energy status sensors and regulators of metabolism. They respond to changes in cellular energy levels, particularly through their sensitivity to NAD+ levels, which fluctuate based on the nutritional state of the cell.

Sirtuins help control metabolic flexibility, or how your body switches between burning carbohydrates and fats:

Carbohydrate metabolism: When you’re not eating, sirtuins (specifically SIRT1) help regulate blood sugar in two phases. Initially, they reduce sugar production, but during longer fasting periods, they activate genes that help maintain stable blood sugar levels.⁴

Lipid metabolism: Sirtuins also help your body use stored fat for energy when food is scarce. They do this by turning on genes that break down fat while turning off ones that store it.

This flexibility is important for adapting to times of limited food intake or intense physical activity, such as during workouts.

One of sirtuins’ most important functions is maintaining genome stability through DNA repair mechanisms.⁵ When cells encounter DNA damage from environmental stressors like UV radiation, pollution, or normal metabolic processes, sirtuins help coordinate the repair response. SIRT1 and SIRT6, in particular, are instrumental in recruiting DNA repair proteins and modifying chromatin structure to facilitate repair processes.

Every day, your cells encounter DNA damage from things like pollution or even normal cellular processes. Sirtuins also help repair this damage, preserving the integrity of your genetic material.⁶ Without this function, cells accumulate errors, leading to aging and age-related diseases.

Beyond DNA repair, sirtuins contribute significantly to cellular stress resistance through multiple pathways.⁷ They activate antioxidant defense systems to combat oxidative stress, regulate mitochondrial function to maintain energy balance, and modulate inflammatory responses.

When sirtuins are active, they help your body adapt to challenges, repair itself, and function more efficiently. But as we age, factors like declining NAD+ levels reduce their effectiveness. This decline leads to many age-related issues, including slower metabolism, reduced cellular repair, and increased inflammation.

Key Takeaway: Sirtuins are NAD+-dependent proteins that act as cellular regulators, managing metabolism, DNA repair, and aging processes by functioning as molecular switches that respond to cellular energy states and help maintain genomic stability.

The Sirtuin Family: Characteristics and Functions

The sirtuin family consists of seven unique proteins, SIRT1 through SIRT7. Each sirtuin has its own job to keep your body functioning optimally and protect it from the effects of aging and disease. Let’s see what makes each of these proteins so important.

Sirtuin	Location	Major Functions	Disease Associations
SIRT1	Nucleus, Cytoplasm	Metabolism regulation Stress response DNA repair Cell survival Circadian rhythm control	Type 2 diabetes, cardiovascular disease, neurodegenerative disorders, cancer
SIRT2	Cytoplasm, Nucleus	Cell cycle regulation Microtubule dynamics Glucose metabolism Inflammation control	Neurodegenerative diseases, cancer, insulin resistance
SIRT3	Mitochondria	Mitochondrial energy metabolism ROS regulation Fatty acid oxidation ATP production	Age-related hearing loss, metabolic syndrome, cancer, cardiac hypertrophy
SIRT4	Mitochondria	Amino acid metabolism Fatty acid oxidation Insulin secretion ATP homeostasis	Type 2 diabetes, cancer, metabolic disorders
SIRT5	Mitochondria	Urea cycle Cellular respiration Ketone body formation ROS management	Cancer, metabolic disorders, cardiovascular disease
SIRT6	Nucleus	DNA repair Telomere maintenance Glucose homeostasis Inflammation regulation	Aging, cancer, type 2 diabetes, cardiovascular disease
SIRT7	Nucleolus	rRNA transcription Chromatin remodeling Stress response Lipid metabolism	Cancer, cardiovascular disease, aging

SIRT1 and SIRT3: The MVPs

An image of matured women doing exercise

Among the sirtuin family, SIRT1 and SIRT3 stand out as the real power players.⁸ They are key to many processes that keep your body running efficiently and aging gracefully.

SIRT1 takes the lead in regulating metabolism⁹ and the stress response. It helps the body adapt to changes in energy availability, like during fasting or exercise, by activating pathways that promote fat-burning and energy conservation. It also manages inflammation and protects cells from oxidative damage, a common contributor to aging and chronic diseases.

What’s particularly fascinating is how SIRT1 also modulates circadian rhythms¹⁰—those 24-hour biological cycles that govern so many of our physiological processes. This circadian connection has significant implications for metabolic homeostasis, helping explain why SIRT1 dysfunction is often linked to metabolic disorders like type 2 diabetes, which are more common as we age.

If SIRT1 governs metabolism, SIRT3 is the guardian of mitochondria, those remarkable cellular organelles that power virtually every biological process in our bodies. SIRT3 optimizes mitochondrial function by regulating energy production,¹¹ controlling reactive oxygen species (ROS), and boosting antioxidant defenses. This intricate balancing act is critical because when ROS production exceeds our antioxidant capacity, the resulting oxidative stress can trigger a cascade of cellular damage that contributes to accelerated aging.

SIRT3 also supports fatty acid oxidation,¹² a process where fats are broken down for energy. It also helps preserve heart health and hearing as we age. Its protective effects on mitochondria are especially critical for organs with high energy demands, like the brain and heart.¹³

As shown in our table above, SIRT1 and SIRT3 operate in different cellular compartments (SIRT1 in the nucleus and cytoplasm, and SIRT3 in the mitochondria), but they both protect your body from the effects of aging and disease. Both help guard against neurodegenerative diseases and reduce the risk of heart-related conditions.

Key Takeaway: SIRT1 and SIRT3 protect against aging by regulating metabolism and maintaining cellular energy production in different parts of the cell.

Sirtuins and NAD+

An image of a matured woman taking supplement

Our understanding of sirtuins and aging comes with a critical caveat – these cellular guardians are only as effective as their fuel supply.

Sirtuins require NAD+ as an essential co-substrate to perform their deacetylation functions, and the steep decline in NAD+ levels as we age – up to 50%¹⁴ – directly impairs sirtuin activity across all seven family members. This diminishing NAD+ availability helps explain why cellular repair, metabolic efficiency, and inflammation control tend to worsen over time.

Interestingly, you can support sirtuin function by replenishing NAD+ levels.¹⁵ NAD+ precursors, such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN), are supplements that help restore NAD+ in the body. With their support for NAD+, these precursors effectively reactivate sirtuins, enabling them to continue protecting your cells and promoting overall health.

Sirtuins and the Aging Process

The relationship between sirtuins and aging represents one of the most fascinating areas of longevity research. As we age, our bodies experience various forms of cellular decline, from decreased energy production to accumulating DNA damage. Sirtuins contribute in either preventing or repairing these age-related changes, earning their reputation as longevity proteins.

At the molecular level, sirtuins influence aging through several key mechanisms. They help maintain genomic stability by coordinating DNA repair processes and managing chromosomal structure, with SIRT6 specifically helping to maintain telomeres¹⁶ – the protective caps at our chromosomes that naturally shorten as we age. Additionally, sirtuins regulate inflammation through multiple pathways,¹⁷ helping combat “inflammaging,” the chronic, low-grade inflammation that contributes to various age-related diseases like Alzheimer’s and dementia.

Perhaps most importantly, sirtuins influence how our cells produce and use energy. They optimize mitochondrial function, helping these cellular powerhouses produce energy more efficiently while generating fewer harmful byproducts. This is particularly significant because mitochondrial dysfunction is a hallmark of aging, contributing to everything from muscle weakness to cognitive decline.

The decline in NAD+ levels particularly affects sirtuin function, creating a vicious cycle where reduced sirtuin activity accelerates various aspects of aging, which in turn further impairs sirtuin function. This understanding has led to growing interest in interventions that can maintain or boost sirtuin activity with age, from NAD+ supplementation and sirtuin activators to exercise, opening exciting possibilities for promoting healthier aging through targeted interventions.

Key Takeaway: Sirtuins are master regulators of the aging process, choreographing cellular health through multiple pathways that directly influence longevity – from DNA repair and inflammation control to energy metabolism optimization and mitochondrial function.

Sirtuins and Caloric Restriction

Caloric restriction (CR) or reducing your calorie intake without depriving yourself of vital nutrients¹⁸ does more than just help with weight management. It activates sirtuins, making them central to the health benefits associated with eating less.

When you practice caloric restriction, your body switches into a survival mode that activates the AMPK pathway, a key energy regulator.¹⁹ This process increases NAD+ levels, which, in turn, boosts sirtuin activity. With more active sirtuins, your body becomes better equipped to repair cellular damage, manage stress, and maintain metabolic balance.

CR has been studied for over 60 years and is the only intervention proven to increase the maximum lifespan in mammals. A study published in the Sage Journals showed that even when CR is started later in life, it still can help extend lifespan.²⁰

Research shows that caloric restriction helps extend lifespan and improve healthspan, and sirtuins help in making this happen. They mediate many of CR’s benefits, such as reducing inflammation, protecting against oxidative stress, and improving energy efficiency in cells.

How to Activate Sirtuins

Sirtuin activation doesn’t require a complete lifestyle overhaul. Small, intentional changes can get these cellular protectors working optimally. Many of these changes also improve your overall health and energy levels.

Regular exercise is one of the simplest and most powerful ways to activate sirtuins. A study published in the International Journal of Molecular Sciences found that physical activity increases NAD+ levels and triggers pathways that improve sirtuin function, especially SIRT1 and SIRT3.²¹ Even brisk walking stimulates these proteins,²² promoting better metabolism, reduced oxidative stress, and improved cellular repair.

Certain natural compounds, like resveratrol, can directly activate sirtuins.²³ Found in foods like red grapes, blueberries, and peanuts, resveratrol mimics the effects of caloric restriction by enhancing SIRT1 activity. While you’d need a lot of these foods to notice benefits, high-quality resveratrol supplements offer a more practical option.

Since sirtuins rely on NAD+ to function, boosting your NAD+ levels is also a surefire way to increase their activity. NAD+ precursors, like NMN and NR, provide the building blocks for your body to produce more NAD+. These supplements can help maintain optimal sirtuin function as you age.

For those seeking a comprehensive solution to optimize their NAD+ levels and support sirtuin activation, Vitality ↑® NAD+ Booster offers a clinically validated formulation that combines key NAD+ precursors with synergistic ingredients. This advanced supplement pairs NMN and nicotinamide with D-ribose and creatine monohydrate to enhance cellular NAD+ production and support optimal sirtuin function.

The unique combination has shown superior efficacy compared to individual NAD+ precursors alone, making it an evidence-based choice for individuals looking to support their cellular health and potentially reduce age-related decline through enhanced sirtuin activation.

The Road Ahead for Sirtuins

An image of an old man and woman preparing healthy foods

As our understanding of sirtuins expands, recent breakthroughs are transforming the field. Scientists have developed next-generation sirtuin activating compounds (STACs) that are up to 10 times more potent than resveratrol, with compounds like SRT1460 showing remarkable selectivity in targeting specific sirtuins.²⁴ Meanwhile, research has unveiled sirtuins’ complex role in cancer biology²⁵ and their potential as diagnostic biomarkers, with SIRT3 and SIRT7 showing particular promise in detecting systemic diseases.²⁶

While supplements and targeted interventions show increasing promise, lifestyle factors like exercise, nutrition, and stress management remain fundamental to optimal sirtuin function. The broad influence of sirtuins – spanning DNA repair, metabolism, and cellular health – makes them crucial targets for promoting healthier aging.

The story of sirtuins reminds us that aging isn’t simply a passive process but one that can be understood and influenced. Through continued research and practical applications, we’re uncovering new ways to support these cellular guardians and potentially extend our healthspan for generations to come.

A mounting body of research shows that supplementing with NMN orally can raise NAD+ levels in the human body which leads to wide ranging benefits.

Here are 11 of the most promising research-backed benefits of taking NMN, from stronger heart function to greater muscular endurance.

Cardiovascular Health

Research published in Aging Cell points to NMN’s potential for improving cardiovascular health and combating age-related vascular problems. When older mice received NMN supplements, their arterial function showed remarkable improvements – blood vessels dilated more effectively and arteries became less stiff.

The study found that NMN works by reducing oxidative stress while boosting protective molecules like elastin in the blood vessels. What’s more, it helped restore SIRT1 activity, an important enzyme for vascular health, while decreasing harmful oxidative byproducts in the arteries¹.

NMN has also shown protective effects against the progression of atherosclerosis. A clinical study in the Journal of Functional Foods showed NMN supplementation effectively reduced the formation of atherosclerotic plaques in mice on a high-fat diet².

Fertility

Research published in Cell Press found that NMN supplementation improved egg quality and increased live birth rates in aging female mice by supporting mitochondrial function³. The study demonstrated that NMN helped counteract age-related decline in egg quality, particularly in older females. While these findings point to NMN’s potential role in maintaining female fertility during aging, research is still needed to confirm similar effects in humans.

Skin Health

A study published in Glycative Stress Research showed that oral NMN supplementation significantly improved multiple aspects of skin health over 8 weeks, including moisture, firmness, and roughness⁴. The study documented meaningful reductions in skin autofluorescence values, indicating lower levels of advanced glycation end products (AGEs) in participants’ skin. Subjects experienced visible improvements in their skin’s appearance, with measurable changes in age spots, wrinkles, and freckles.

Cognitive Health

Research in Redox Biology showed that NMN supplementation for two weeks restored neurovascular coupling responses in aged mice to youthful levels while improving their spatial memory and movement coordination⁵. The cognitive improvements stemmed from reduced oxidative stress and better blood vessel function in the brain, with the study pointing to NMN’s role in restoring NAD+ levels and mitochondrial function.

Digestive System Health

A recent study in the Journal of Translational Medicine revealed that NMN supplementation led to significant improvements in digestive health, with participants reporting less abdominal pain, bloating, and constipation⁶.

The research showed NMN increased beneficial gut bacteria populations, particularly Bifidobacterium and Faecalibacterium, while strengthening the intestinal barrier and lowering inflammation markers. These findings demonstrate NMN’s valuable role in promoting gut microbiome health and alleviating digestive discomfort.

Metabolic Health

A 2011 pilot study at Washington University School of Medicine explored NMN as both a biomarker and potential treatment for age-related metabolic disorders⁷. Mouse studies revealed that aging and high-fat diets impaired NAMPT-mediated NAD biosynthesis, leading to type 2 diabetes development.

NMN treatment improved insulin sensitivity and function while restoring genes linked to oxidative stress, inflammation, and circadian rhythm in diabetic mouse livers through SIRT1 activation.

DNA Repair

A review article by Rahman et al. published in Aging and Disease discusses how NMN supplementation reduces DNA damage and cellular aging in both mouse models and human cells⁸.

The compound works by raising NAD+ levels and activating PARP1, which helps repair damaged DNA strands. These findings point to NMN as a potential treatment for preventing and reversing age-related DNA deterioration.

Eye Function

A 2023 review examined NMN’s role in treating eye diseases, drawing from recent literature and original research. Studies in mice demonstrated that NMN helped regulate inflammation, oxidative stress, and metabolism in conditions like glaucoma, retinopathy, and macular degeneration⁹.

Findings point to NMN as a promising treatment for various eye disorders, but researchers note that more preclinical studies are needed to validate these results.

Energy Levels

Research shows NMN supplementation helps restore NAD+ levels¹⁰, which supports healthy energy metabolism and mitochondrial function. This increased NAD+ availability allows for better cellular energy production and improved metabolic efficiency¹¹. NMN supplementation may also optimize sirtuin proteins’ ability to regulate energy at the cellular level through its effects on NAD+.

Anti-Aging

A review by Harshani et al. explores NMN’s potential as an anti-aging compound¹². Animal studies suggest NMN supplements can improve conditions like diabetes, cardiovascular disease, and neurodegenerative disorders through their effects on mitochondrial function, oxidative stress levels, and DNA repair mechanisms.

These cellular improvements may help slow the aging process, though research is ongoing to confirm findings in humans.

Muscle Endurance

In a six-week randomized, double-blind, placebo-controlled trial, researchers found that NMN supplementation improved ventilatory threshold and aerobic capacity in amateur runners¹³.

The improvements were dose-dependent and centered on skeletal muscle efficiency rather than cardiac function, with NMN increasing oxygen utilization in muscle tissue. These findings point to NMR supplementation combined with training as a promising approach for improving athletic endurance.

How Long Do the Effects of NMN Take to Work?

The timeline for experiencing NMN’s benefits varies depending on the specific health aspects you’re targeting and your individual biology. Research and user experiences suggest different timeframes for various effects:

Immediate Energy Effects (Hours to Days): Some users report feeling increased energy and mental clarity within the first few days of supplementation, as NMN begins supporting cellular NAD+ production.
Short-Term Benefits (2-4 Weeks): Improvements in physical performance, exercise capacity, and energy metabolism typically become noticeable within the first month of consistent supplementation.
Mid-Term Changes (1-3 Months): Skin health improvements, better sleep quality, and cognitive function benefits often become apparent during this period, as demonstrated in several clinical studies.
Long-Term Benefits (3-6 Months+): More fundamental improvements in cardiovascular health, metabolic function, and age-related markers typically require several months of consistent supplementation to become noticeable.
Preventive Benefits (Ongoing): Some of NMN’s most important effects, such as DNA repair and longevity support, work continuously in the background and may not have immediately noticeable effects but contribute to long-term health maintenance.

NMN Supplement Dosage Ranges

Research has shown that NMN supplementation can be effective across various dosage ranges, with studies demonstrating benefits from as low as 250 mg up to 1200 mg daily. The right dosage depends on individual factors and specific health goals, though most research centers on a few key ranges.

Starter Dose (250-300 mg/day): Ideal for beginners and shown effective in clinical studies for raising NAD+ levels, particularly in healthy adults looking for general wellness support.
Standard Dose (500-750 mg/day): The most commonly studied range, demonstrating optimal results for physical performance and NAD+ concentration in blood, with strong safety data behind it.
Advanced Dose (900-1200 mg/day): Higher doses studied in specific research settings, showing good tolerability for up to 8 weeks, typically reserved for specific therapeutic purposes or older adults.
Maintenance Dose (250-500 mg/day): Often recommended for long-term daily supplementation after achieving desired results with higher doses.

Your optimal NMN dosage should consider factors like age (older adults may benefit from higher doses), body weight, overall health status, and specific wellness goals. Most experts recommend starting at a lower dose (250 mg) and gradually increasing if needed while monitoring your body’s response. For sustainable results, consistency in supplementation is often more important than taking maximum doses.

Jinfiniti’s Pure NMN powder supplement comes in a convenient powder form, making it easy to control and adjust your daily dosage.

NMN Benefits: Key Takeaways and Future Prospects

The research surrounding NMN supplementation continues to paint a compelling picture of its potential impact on human health and longevity.

Does NAD+ Help With Menopause Symptoms?

Written by Jinfiniti Science on December 6, 2024. Posted in NAD+, Menopause, NAD, NAD+ Precursors. No Comments on Does NAD+ Help With Menopause Symptoms?

Hot flashes, night sweats, mood swings, sleep disturbances, and memory loss—these are just a few of the challenging symptoms women experience during menopause.

While they are often considered a natural part of the transition, these symptoms can severely impact your daily life, leaving you feeling drained, frustrated, and disconnected from your usual self.

The good news is that you don’t have to just accept them. There are effective ways to manage—and even alleviate—these discomforts.

One promising approach involves a critical coenzyme called NAD+ (nicotinamide adenine dinucleotide). Replenishing your body’s NAD+ and supporting cellular health may ease and even alleviate menopause symptoms, helping you feel more like yourself during this transition.

In this article, we discuss…

How menopause symptoms impact daily life and why they shouldn’t be accepted as inevitable
The connection between NAD+ depletion and ovarian aging through CD38 enzyme activity
How NAD+ supports key biological processes during menopause
Strategies for restoring NAD+ levels to manage menopause symptoms effectively

Common Symptoms of Menopause

AN image of a woman suffering from menopause

Menopause is a natural phase in a woman’s life that marks the end of her reproductive years,¹ typically occurring in her late 40s to early 50s. During this time, estrogen levels fluctuate and eventually decline, leading to a range of physical and emotional changes, including:

Hot flashes and night sweats
Mood changes and irritability
Fatigue and low energy
Sleep disturbances
Cognitive issues (brain fog)
Vaginal dryness
Weight gain
Bone density loss
Lower libido
Loss of skin elasticity
Health problems due to hormonal changes

While these symptoms are often considered a normal part of aging, they can be overwhelming and disrupt your daily life. But you don’t have to simply endure them. By understanding what’s happening, you can take control and take proactive steps to help you live a healthy, balanced life—even during menopause.

NAD+ and Ovarian Aging

Ovarian aging is the gradual decline in ovarian function² that comes with age. As you enter your late 30s and 40s, changes in your hormones, such as reduced estrogen, can cause irregular periods and fewer high-quality eggs.

One of the reasons for this? A decrease in NAD+ levels as you age.

While NAD+ decreases across the body, the ovaries experience a more rapid decline³, affecting their function. This accelerated depletion of NAD+ is largely driven by an enzyme called CD38.

Research shows that CD38 activity increases in aging ovaries⁴, making them more vulnerable to a faster depletion of NAD+ compared to other tissues. This loss plays a major role in ovarian aging, leading to a decrease in ovarian follicles and a drop in estrogen production, which, in turn, causes common menopausal symptoms like hot flashes and mood swings.

But that’s not all. Low NAD+ levels in the ovaries are linked to a range of issues that affect reproductive health, including:

Reduced egg (oocyte) quality
Follicle depletion
Changes in gene expression related to aging, DNA repair, and inflammation

In fact, a recent study published in Ovarian Research found that low NAD+ levels can impair the energy metabolism of oocytes⁵, reducing their metabolic activity and impacting egg quality. This decline can have a major effect on fertility and reproductive health.

In addition to these metabolic changes, reduced NAD+ also alters gene expression in the ovaries, particularly genes involved in cellular aging and inflammation⁶. This creates a cycle that accelerates the aging process, leading to further declines in reproductive health.

Here’s the good news: you can turn things around.

By targeting CD38, you can potentially reverse some of the damage caused by NAD+ depletion in the ovaries. This has been shown in a study published in Nature, where researchers found that inhibiting or deleting CD38 significantly boosts NAD+ levels in the ovaries⁷, helping improve egg quality and even preserving fertility in aging mice.

This research suggests that by raising NAD+ levels and regulating CD38, you can significantly support ovarian health and even preserve fertility as you age. CD38 can be inhibited by flavonoids like apigenin and quercetin⁸, which is a main ingredient in our SenoAid senolytic supplement.

Key Takeaway: Research suggests that declining NAD+ levels in aging ovaries, driven by increased CD38 enzyme activity, significantly impact reproductive health and fertility, but targeting CD38 with specific compounds may help preserve ovarian function.

How NAD+ Can Relieve Menopause Symptoms

An image of an aging woman suffering from menopause

Maintaining optimal NAD+ levels during menopause is associated with several biological processes that influence common symptoms:

Cellular energy production: NAD+ serves as a critical coenzyme in mitochondrial function, directly impacting energy levels and fatigue resistance
Brain cell efficiency: Adequate NAD+ helps support neuronal health and cognitive function through enhanced mitochondrial activity and SIRT1 activation
Circadian rhythm regulation: NAD+ is essential for proper circadian rhythm function through the NAMPT-mediated salvage pathway, influencing sleep patterns
Cellular repair mechanisms: NAD+ enables DNA repair processes through PARP activation, supporting overall cellular health
Metabolic function: As a key metabolic regulator, NAD+ helps maintain efficient energy utilization and metabolic flexibility

While NAD+ levels naturally decrease during menopause, maintaining optimal cellular concentrations can support the body’s ability to manage this transition effectively.

NAD+ and Libido During Menopause

When you reach menopause, it’s not just the hot flashes and sleepless nights that can throw you off—it’s your libido, too. If you’ve been feeling a little less interested, you’re not alone.

But why does this happen?

The answer lies in NAD+. As we went over earlier, our NAD+ levels naturally decline with age, and this affects many processes in our bodies, from energy production to hormone regulation.

As menopause sets in, declining levels of estrogen and testosterone can naturally lower your sex drive even more. On top of that, reduced NAD+ levels can leave you feeling drained, irritable, and stressed⁹—none of which help your desire.

Fortunately, increasing NAD+ might be just what you need to reignite that spark. Here’s why:

Hormonal Balance: NAD+ supports the hormones that drive your libido¹⁰, including estrogen and testosterone. By boosting NAD+ levels, you help keep those hormones in check.
Neuroprotection: NAD+ protects your brain and reduces oxidative stress¹¹, which can improve mood, lower stress, and promote arousal.
More Energy: NAD+ fuels your cells, boosting your overall energy¹² and giving you more vitality for intimacy.
Better Mood: By fighting fatigue and mood swings¹³, NAD+ helps you feel emotionally balanced and ready to enjoy a deeper connection.

With optimal support for your NAD+ levels, you can reclaim not just your energy and vitality but your libido as well, bringing back the passion you thought menopause had taken away.

Restoring NAD+ Levels Before and After Menopause

NAD+ precursors are compounds that our cells can use to generate new NAD+ molecules. The most well-studied and effective precursors include:

Nicotinamide Mononucleotide (NMN)
Nicotinamide Riboside (NR)
Nicotinamide (a form of vitamin B3)

Supplementing with these precursors has been shown in studies to raise NAD+ levels in tissues throughout the body. As we have already seen, restoration of NAD+ can help reignite the cellular engines that power our metabolism, repair damaged DNA, activate longevity genes, and enable our cells to function at more youthful levels.

For women seeking a comprehensive NAD+ restoration strategy, products that combine multiple precursors may offer additional benefits. Scientifically formulated supplements, like our Vitality ↑® NAD+ Booster, provide a synergistic blend of NMN, Nicotinamide, and other bioactive ingredients to optimize NAD+ production and support healthy aging processes through menopause and beyond.

Whether you are proactively planning for menopause or already navigating this transition, incorporating NAD+ precursors into your wellness routine can provide a foundational strategy for nourishing cellular vitality. By restoring and maintaining healthy NAD+ levels, you can equip your cells with the resources they need to thrive, empowering you to age with resilience and grace.

Can NAD+ Help Treat Alzheimer’s Disease and Dementia?

Written by Jinfiniti Science on December 2, 2024. Posted in NAD+, Memory Loss and Brain Fog, NAD, NAD+ Precursors, Neurological Diseases. No Comments on Can NAD+ Help Treat Alzheimer’s Disease and Dementia?

Alzheimer’s disease is affecting more people than ever, with 6.7 million Americans aged 65 and older living with it today. By 2050, that number is expected to more than double. Globally, over 55 million people are dealing with Alzheimer’s or other forms of dementia, creating challenges not just for them, but for their families too.

Right now, most treatments focus on managing symptoms, not fixing the root of the problem. That’s why there’s a growing push for new, more effective solutions—and nicotinamide adenine dinucleotide (NAD+) might be one of them.

NAD+ is the coenzyme behind every cell’s ability to thrive – it drives energy production, repairs DNA, and governs how your genes are expressed. As we age, NAD+ levels naturally decline, and this decrease is associated with neurodegeneration and cognitive impairment—hallmarks of conditions like Alzheimer’s disease.

A growing body of research is examining the relationship between NAD+ and neurodegenerative conditions, with studies suggesting that maintaining healthy NAD+ levels could help shield against the devastating effects of Alzheimer’s and dementia.

So, what makes this coenzyme so compelling for keeping our minds sharp as we age?

In this article, you will discover:

The critical relationship between NAD+ and neurodegeneration, exploring how this essential coenzyme impacts brain health at the cellular level
Clinical evidence supporting NAD+ supplementation in Alzheimer’s disease, including detailed research on nicotinamide, NMN, and nicotinamide riboside
Practical NAD+ treatment approaches, from IV therapy to scientifically-validated precursor compounds like Vitality ↑® NAD+ Booster
The importance of testing and monitoring NAD+ levels to proactively support cognitive health and prevent decline

The Link Between NAD+ and Neurodegeneration

Your cells rely on NAD+ like a conductor relies on their baton – the coenzyme coordinates numerous biological processes with precision that determines how well your body functions at its most fundamental level.

As we age, NAD+ levels in various tissues, including the brain, significantly decrease¹. This decline has been linked to the development of various age-related conditions, including neurodegenerative diseases like Alzheimer’s and Parkinson’s.²

NAD+ is essential for mitochondrial function and energy production. In neurodegenerative diseases, decreased NAD+ levels leads to multiple factors that contribute to neuronal death and axonal degeneration, hallmarks of these diseases:

Impaired mitochondrial function³
Increased reactive oxygen species (ROS) production⁴
Compromised cellular energy metabolism⁵
Impaired DNA repair mechanisms and reduced sirtuin activity⁶

The decline in NAD+ levels during aging and neurodegeneration is primarily due to:

Increased NAD+ consumption by enzymes such as CD38 and PARPs
Reduced expression of NAMPT, a key enzyme in the NAD+ salvage pathway
Activation of SARM1, a recently discovered NAD+ hydrolase that can rapidly deplete neuronal NAD+ levels⁷

Perhaps most intriguingly, reduction in NAD+ levels occurs before the onset of neurodegenerative symptoms, suggesting it may contribute to disease progression rather than being merely a consequence⁸.

Clinical Evidence for NAD+ in Alzheimer’s Disease

As Alzheimer’s disease (AD) becomes increasingly prevalent, researchers are exploring innovative therapies like NAD+ precursors to combat this devastating condition. But is NAD+ a potential treament for Alzheimer’s or just another overhyped trend? Let’s look at the evidence.

Nicotinamide (NAM) vs Placebo

A 2021 review published in Frontiers in Cell and Developmental Biology⁹ provides a comprehensive overview of the systematic therapeutic evidence for NAD+ and its precursors in Alzheimer’s disease models.

NAM, the amide form of vitamin B3, showed significant potential in seven preclinical trials for Alzheimer’s disease treatment:

NAM treatment improved spine density in neurons from AD mice, suggesting a neuroprotective role.¹⁰
A controlled delivery system of NAM reduced cognitive impairment and decreased phosphorylated tau in early-stage AD rats.¹¹
NAM pretreatment reduced expression of genes associated with AD and increased SIRT1 in brain tissues.¹²
NAM supplementation protected against Aβ-induced oxidative stress and reduced markers of cell death in rat AD models.¹³
Long-term NAM treatment improved cognitive performance, preserved mitochondrial integrity, and reduced AD pathology in mice.¹⁴
NAM reduced phosphorylated tau and prevented cognitive deficits in a mouse model of AD.¹⁵

More recently, a phase 2a proof-of-concept trial¹⁶ investigated the use of nicotinamide (a form of vitamin B3 and NAD+ precursor) in early Alzheimer’s disease:

47 participants received either 1500 mg of nicotinamide twice daily or placebo for 12 months.
Treatment resulted in significantly less change on the Clinical Dementia Rating-Sum of Boxes (CDR-SB) compared to placebo.
While not statistically significant, changes in cerebrospinal fluid (CSF) biomarkers favored nicotinamide.
The therapy showed a safe profile with balanced adverse events.

Nicotinamide Mononucleotide (NMN) vs Placebo

Outlined in the same 2021 review as above, NMN, a direct precursor to NAD+, has demonstrated efficacy in four AD models:

NMN improved memory in transgenic nematode AD models through a mechanism dependent on mitophagy.¹⁷
NMN treatment decreased Aβ production, synaptic loss, and inflammation in transgenic AD mice by inhibiting JNK activity.¹⁸
In Aβ-injected rats, NMN improved cognitive function, reduced neuronal cell death, and decreased oxidative stress.¹⁹
NMN reversed deficiencies in oxygen consumption and reduced levels of mutant APP in AD mice²⁰.

The most recent study, conducted by Fang et al. in 2019²¹, investigated the effects of NAD+ repletion on AD pathology using both animal models and human cell cultures.

The study found that NAD+ levels were significantly reduced in both the hippocampus and cerebral cortex of AD model mice. This depletion was associated with decreased activity of SIRT3, a NAD+-dependent deacetylase.

Restoring NAD+ levels through nicotinamide mononucleotide (NMN) administration:

Normalized NAD+ levels
Restored mitochondrial function
Reduced reactive oxygen species (ROS)
Decreased DNA damage
Improved neuroplasticity
Enhanced cognitive function in AD model mice

Nicotinamide Riboside (NR) vs Placebo

A study by Xie et al. published in Metabolic Brain Disease in 2019²² provides important evidence for the potential benefits of NR supplementation in Alzheimer’s disease and aging.

NR supplementation improved short-term spatial memory in aged mice and enhanced contextual fear memory in AD model mice.
NR inhibited the accumulation of amyloid-β (Aβ) in AD model mice and reduced the migration of astrocytes to Aβ plaques.
NR supplementation inhibited the activation of astrocytes in aged mice.
NR decreased the elevation of serum nicotinamide phosphoribosyltransferase (NAMPT) in aged mice, potentially indicating reduced inflammation.

Moreover, a 2020 review of the protective effects of NR against cognitive impairment²³ found that NR has shown the ability to:

Inhibit the accumulation of pathological hallmarks of Alzheimer’s disease
Improve learning and memory in various murine models for dementia
Reduce DNA damage, neuroinflammation, and apoptosis
Improve hippocampal synaptic plasticity in diabetic mice and an Alzheimer’s disease mouse model

The evidence paints an intriguing picture: declining NAD+ levels in brain cells appear to be a hallmark of aging and contribute significantly to the pathology of Alzheimer’s disease. Perhaps most exciting is the prospect that a simple, safe vitamin-based intervention could help protect our aging brains.

While more research is needed, the possibility of an accessible and affordable approach to neuroprotection offers hope in our ongoing fight against Alzheimer’s disease.

NAD Treatment Approaches

As we age and face increasing cognitive challenges, maintaining optimal NAD+ levels becomes an important piece of the puzzle for supporting brain health and potentially reducing the risk of Alzheimer’s and dementia. Here’s a look at two primary treatment approaches to optimizing your NAD+ levels for cognitive function and neuroprotection.

NAD IV Therapy

While NAD+ IV therapy has gained popularity in recent years, its efficacy in treating Alzheimer’s disease remains largely unproven. Current evidence is limited to a single case report where one patient showed subjective improvements in memory and overall attitude. It’s important to understand that NAD+ IV infusion primarily increases extracellular NAD+ levels, without necessarily improving intracellular concentrations where the molecule’s beneficial effects primarily occur.

Moreover, patients should be aware of potential side effects associated with NAD+ IV therapy. The invasive nature of IV administration and the lack of comprehensive clinical studies make this approach less favorable compared to other available options for supporting cognitive health.

NAD+ Precursor Compounds

In contrast to IV therapy, NAD+ precursor compounds have demonstrated substantial promise in scientific research, as detailed in our previous section. These compounds work by providing the building blocks your body needs to naturally increase cellular NAD+ levels, potentially supporting cognitive function and neurological health.

For those seeking an evidence-based solution to optimize their NAD+ levels, our NAD boosting supplement Vitality ↑® offers a clinically validated formulation that combines proven NAD precursors NMN and nicotinamide with D-ribose and creatine monohydrate.

This synergistic blend represents a significant advancement in NAD+ supplementation. The carefully selected ingredients work together to:

Enhance cellular NAD+ production
Support comprehensive cellular regeneration
Optimize energy metabolism
Promote cellular repair mechanisms

What sets Vitality ↑® NAD+ Booster apart is its superior efficacy compared to individual NAD+ precursors. Users consistently report notable improvements in their overall health and performance after achieving optimized NAD+ levels through this comprehensive formulation.

The clinical validation behind this unique combination of ingredients makes Vitality ↑® NAD+ Booster an excellent choice for individuals looking to support their cognitive health and potentially reduce their risk of age-related cognitive decline.

Revolutionizing America’s Health: My Journey and Shared Vision with RFK Jr.

Written by Jinfiniti Science on November 28, 2024. Posted in Obesity and Weight Gain, Guest Blog. No Comments on Revolutionizing America’s Health: My Journey and Shared Vision with RFK Jr.

America is facing a health crisis of epic proportions. Chronic diseases like obesity, diabetes, and heart disease have become the norm rather than the exception.

Our food system is flooded with ultra-processed, nutrient-devoid products, and the healthcare system focuses more on treating symptoms than addressing root causes.

For decades, I lived as both a victim of this broken system and an unwitting contributor to it. My journey—from battling obesity to pioneering solutions—led me to a revelation: we can, and must, Make America Healthy Again (MAHA).

What started as a personal battle turned into a movement, one that aligns closely with leaders like Robert F. Kennedy Jr., who dares to question the status quo of our healthcare and food systems.

RFK Jr. has famously spoken out about the inadequacies of medical practices and government policies, shedding light on the systemic failures that perpetuate poor health. I share his passion for truth and reform. Together, our shared mission is to empower Americans to reclaim their health—not through fads or gimmicks, but through education, real food, and science-backed solutions.

The Early Struggles: Living the Problem I Wanted to Solve

An image of Chuck Nix with his companion towards his advocacy

My name is Chuck Nix, and my journey to health advocacy has been a long road of personal struggle, revelation, and relentless perseverance. Born in Dallas, Texas, in 1959 and adopted at birth, I grew up in a household where processed and junk food reigned supreme.

Although my adoptive parents were normal weight, I quickly became one of those rare, chubby kids in my era. Food was comfort, habit, and, unknowingly, the root of my lifelong health challenges.

By ninth grade, I weighed 210 pounds at 5’9″ and was already struggling with my weight and the desire to fit in. I attempted my first “diet” then, starving myself to lose weight, but I was constantly hungry, and the weight just came back. This set off a decades-long cycle of yo-yo dieting, reaching extremes.

As an adult, standing at 6’2″, I hit a low of 160 pounds in 1985 through intense exercise and strict calorie restriction. But it was unsustainable—I was thin, not fit, and the weight eventually crept back on.

My weight was a constant battle—one that followed me through every phase of life. I tried calorie restriction, extreme exercise, and countless diets, all while following the outdated, low-fat, high-carb dietary advice of the time.

Over the years, my weight fluctuated wildly, reaching a high of 315 pounds in 2018. I nearly died that year. In my 20s and 30s, I tried everything I could think of: severe calorie restriction, sometimes eating only 1200 calories a day, paired with hours of exercise. But high-stress jobs and lack of time always led me back to quick meals at the drive-thru.

Every time I lost weight, I seemed to gain it back with a vengeance.

In 1991, I met my biological family, and what I saw was eye-opening: my biological mother’s side of the family was obese, with one of my half-brothers even reaching 465 pounds. It was a warning of what could have been me without discipline.

Around this time, I made a serious effort to get fit, following the low-fat advice of doctors, working out at two gyms, and jogging five miles daily. After six years of dedication, I’d only managed to get down to 240 pounds. I felt like a failure, but little did I know, I had been misled.

The turning point came in late 1999 when I discovered the Atkins Diet.

The initial “induction phase” was ketogenic, and in just 3.5 months, I lost 60 pounds with zero exercise. I felt fantastic for the first time in years and was determined to finally achieve the fit, healthy body I had chased for so long.

I hired a personal trainer, but he warned me that Atkins was dangerous and could destroy my liver and kidneys. Trusting his advice, I compromised, adding more carbs.

The result? I gained 40 pounds of fat and became re-addicted to carbs. I ended up suing the gym and got my money back, but I felt utterly defeated.

For decades, I believed I was failing, but in reality, the system was failing me.

Science now shows that the food pyramid we were taught to follow in the 1980s was built on flawed assumptions and industry influence. High-carb, low-fat diets were a recipe for insulin resistance, metabolic disorders, and cravings that kept us dependent on sugar-laden foods.

My health continued to spiral. By 2003, I’d made a career shift and finally achieved a dream of mine: founding my frozen dessert company, Silky Smooth Frozen Custard.

This was the first Wisconsin-style frozen custard shop in Beverly Hills, and later evolved into Silky Smooth MicroCreamery, which won “Best Ice Cream in LA” in 2007.

The shop attracted celebrities like Kim Kardashian and Tyra Banks, but it all came crashing down with the Great Recession in 2008. I lost everything—my business, my credit, my hope. From there, I hustled in the world of credit funding, eventually building up to a six-figure business. And then COVID hit, and it all crumbled once again.

The Breakthrough: Science Meets Personal Experience

In 2016, I stumbled across the show My Diet is Better Than Yours, which highlighted the ketogenic diet, helping a man in his late 50s lose significant weight.

I was angry—had I been lied to all those years? More research led me to Dr. Eric Berg, who taught me the truth about keto and intermittent fasting. I finally found an approach that worked for me, dropping 100 pounds in nine months with no exercise.

I felt decades younger, but more importantly, I felt in control for the first time. I learned that sugar was poison, and I became determined to help others find freedom from it.

Armed with this new knowledge, I decided to bring back my dessert brand as an all-keto operation. I spent years developing SilkySweet®, an all-natural, sugar-free sweetener that tasted better than cane sugar and cured my own sugar cravings.

SilkySweet® was originally created to replace the “forced by law” use of Sucralose in Silky Smooth frozen desserts, reformulating them to meet future Ketogenic Certified health standards. Through extensive R&D, we developed a formula superior to cane sugar, leading me to market it globally as the ultimate, realistic cure for sugar addiction.

I even created SilkySweet KetoCola, a sugar-free cola that was preferred three to one over Mexican Coca-Cola in taste tests. Despite my breakthroughs, COVID delayed production, inflation spiked, and my business struggled to take off. Personal credit was once again destroyed, and I faced setback after setback.

From Personal Mission to National Movement

In 2022, I had a moment of clarity: my mission was bigger than just selling products. I needed to help Americans break free from the toxic food system that was driving chronic disease and obesity.

Inspired, I initially came up with the concept of “Make America Healthy Again” (MAHA) and created a prototype purple hat to symbolize unity by merging red and blue.

However, I soon evolved the phrase to “Making America Healthy Again” and produced 500 hats.

The shift from “Make” to “Making” reflects a move from a campaign promise—set to expire on 11/5/24—to an active, ongoing mission of healing and curing, embodied by the world’s only realistic solution for sugar addiction: SilkySweet.com.

Like many breakthrough ideas that show up concurrently in different geographic areas and even cultures, this vision, MAHA, caught fire with movers and shakers, including Robert F. Kennedy Jr., long a champion of health reform.

The first purple MAHA hats symbolized my call for unity across all demographics and political divides, with red and blue merging into purple, a call for health transformation and healing in America.

In 2023 I took a gamble and exhibited at an anti-aging/health event. I caught the bug and got Longevity Fever.

I immersed myself in education and made contacts that have proven very beneficial for my MAHA movement. I had been taking an NAD+ supplement that was not working and discovered Jinfiniti Precision Medicine and their Vitality Boost NAD+ “Optimizer.” (The technical description of the product is actually NAD+ Booster supplement. These are the things you learn when you take the deep dives!)

Like so many other consumers who believe that all supplements are created equal, I got schooled in the importance of using data-driven, science-backed products, and in particular, the need to optimize my intracellular NAD.

I met Dr. Jin-Xiong She, Jinfiniti’s Founder and Chief Scientist.

Jinfiniti’s Special Projects Director, Greta Blackburn, was moderating a panel at the event and, upon hearing of my mission, introduced me to her panel member Dr. Robert Lufkin, author of “Lies I Taught In Medical School’ and a USC Professor. Dr. Lufkin and I shared so many common beliefs and he, like Dr. Eric Berg, who set me straight on Keto, are part of my semi-official Advisory Team as the mission moves forward.

Dr. Lufkin and I touched base only briefly at that ’23 event but at the same event the following year we had time to share some conversations and today I reach out to him regularly for his expertise and highly material insights for the MAHA cause.

In 2024, something remarkable happened. After switching to a full carnivore diet, I received life-changing blood test results and adjusted my macros to 80% fat.

Almost overnight, my vision, which had been compromised since I was a child, transformed. My eyesight returned sharper than ever—20/10 in both eyes—and I could see in 3D for the first time since childhood, all without the need for glasses or contact lense.

I knew then that my mission was not only to heal myself but to bring real health solutions to every American.

The RFK Jr. Connection: A Shared Vision for Health Reform

An image showing the advocacy to make America healthy again

In September 2024, I took MAHA to the Senate hearings in Washington, D.C., where I met Senator Ron Johnson, and Calley and Casey Means. Thanks to a friend who helped with travel costs, I witnessed firsthand the growing momentum for healthcare reform. I knew that MAHA was not just a vision but a movement with real potential to change lives.

It was recently announced that RFK Jr. is being appointed as the next Secretary of Health and Human Services. I am excited about the possibilities for my MAHA mission combined with his.

Sometimes we feel that our ideas, journeys, and trials and tribulations are all for naught. I’m here to tell you that we can all use our passion as fuel to make change. It takes work. It means sacrifice, but in the end, miracles can happen, relationships can be forged, and change can happen.

Today, I work alongside pioneers like Dr. Jin-Xiong She, who introduced me to Jinfiniti’s anti-aging supplements, and Greta Blackburn- formerly known as The Telomere Diva for her part in the launch of TA Sciences, and for her role in developing and co-writing the layman’s book on telomeres, “The Immortality Edge”– who immediately saw the potential in MAHA.

Greta now calls herself a NAD Nerd and a MAHA Mafiosa!

Together, we’re pushing forward with the vision to Make America Healthy Again, one taste bud and one American at a time.

My journey has been filled with struggles, but each one has brought me closer to this mission. As I stand here today, with my iconic purple MAHA hat and years of hard-earned wisdom, I’m more committed than ever to making this vision a reality.

NMN and NR Compared: Better Together or Choose One?

Written by Jinfiniti Science on November 26, 2024. Posted in NAD+, NAD, NAD+ Precursors. No Comments on NMN and NR Compared: Better Together or Choose One?

What if the secret to feeling younger and staying healthier lies within your cells?

Meet NAD+ (nicotinamide adenine dinucleotide) — a dynamic coenzyme that keeps your body running at its best. From energy production to repairing DNA and maintaining cellular health, NAD+ is a driving force behind a myriad biological processes that impact how you feel and function every day. But as we age, our NAD+ levels decline, leading to slower metabolism, fatigue, and other age-related challenges.

While our cellular fuel tanks deplete as we get older, scientists have identified two key compounds that may help refill it: nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR). These precursor molecules act as building blocks for NAD+, offering a potential solution to age-related NAD+ decline. With mounting evidence supporting their efficacy, NMN and NR are rapidly becoming central figures in the field of longevity research

The scientific community has been working to determine which of these compounds might be more effective at boosting NAD+ levels – and the answer isn’t so straightforward. Each precursor has unique properties and cellular pathways, leading us to explore an intriguing possibility: could combining NMN and NR together offer advantages that neither compound can achieve alone?

In this article, you will learn:

The fundamental differences between NMN and NR as NAD+ precursors, including their unique molecular structures and how they’re processed differently in your body’s cells
How bioavailability impacts the effectiveness of these supplements, including the complex roles of transporters, enzymes, and gut bacteria in their absorption
What clinical research reveals about both compounds’ effectiveness and safety profiles, with data from human trials showing their impacts on NAD+ levels and health outcomes
How to make an informed choice between NMN, NR, or a combination approach based on your specific health goals, supported by cellular-level testing to optimize your supplementation strategy

NMN vs NR: Different Precursors, Different Pathways

An image of scientist exploring NMN and NR

NMN and NR are two of the most well-known NAD+ precursors, studied fairly extensively for their ability to increase NAD+ levels, support cellular energy, and promote long-term health. But while they share a common goal, their unique structures and metabolic pathways set them apart in how they influence your body’s health.

NMN is a larger molecule made up of a nicotinamide group attached to a ribose sugar and a phosphate group¹. This makes it more complex than NR, which is simply nicotinamide linked to ribose, without the extra phosphate².

This structural difference is critical in how each precursor is absorbed and utilized. For example, NMN can be directly absorbed by cells in some tissues, but in other tissues, it needs to be converted into NR before entering cells. NR, on the other hand, can be directly converted into NMN inside the cell.

The pathways that transform NMN and NR into NAD+ also follow different processes. NMN is primarily synthesized in the cell through a process called the salvage pathway³, where it’s created from nicotinamide with the help of an enzyme called NAMPT. Once inside the cell, NMN is converted to NAD+ through another enzyme, NMNAT.

In contrast, NR is phosphorylated by NR kinases (NRK1/NRK2) to form NMN,⁴ which then goes through the same process to become NAD+. Additionally, NR is absorbed by cells through specific transporters or can be metabolized in the gut to nicotinamide, which also contributes to NAD+ production.

Both NMN and NR are highly effective at increasing NAD+ levels, but their structural and metabolic differences can influence absorption efficiency and how quickly they act in the body. NMN’s ability to bypass certain steps may make it more effective in specific tissues, while NR’s smaller size allows for broader cellular uptake.

Choosing the right precursor depends on your health goals and how your body responds to each. Understanding these distinctions can help you tailor your approach to boosting NAD+, supporting cellular repair, and combating the effects of aging.

Key Takeaway: While both NMN and NR effectively boost NAD+ levels, their distinct molecular structures and metabolic pathways (with NMN being larger and containing an extra phosphate group compared to NR) lead to different absorption mechanisms and cellular utilization patterns in the body.

Bioavailability of NR and NMN

To truly benefit from NAD+ precursor supplementation, absorption is everything. So here’s the burning question: when it comes to NR versus NMN, which one does your body soak up like a sponge—and which one might just take an express trip to your bladder?

The bioavailability of NR and NMN is more complex than initially understood, and recent research has challenged some earlier assumptions about how these compounds are processed in the body.

Both NR and NMN undergo complex metabolic transformations before contributing to NAD+ synthesis. While earlier theories suggested NR might have superior absorption due to its smaller size⁵, current evidence paints a more nuanced picture. NR is likely absorbed intact and enters cells via equilibrative nucleoside transporters, where it’s converted to NMN.

Conversely, NMN may be directly transported into cells through a recently identified transporter (SLC12A8) in mice⁶, though its function in humans isn’t yet fully understood. Often, NMN is dephosphorylated to NR before cellular entry, then reconverted to NMN inside the cell⁷.

The metabolic pathway involves multiple steps influenced by various factors, including gut bacteria. The microbiome can deamidate NMN to nicotinic acid mononucleotide (NAMN), affecting its overall absorption and utilization⁸. While both compounds can be converted to nicotinamide (NAM), this isn’t the sole pathway. The process is more intricate than previously thought, involving a complex interplay of enzymes and transporters.

Clinical studies have demonstrated that both NR and NMN supplements can effectively increase NAD+ levels in human tissues, though their impact varies based on factors such as dosage, duration of use, and individual physiological differences.

Key Takeaway: While both NR and NMN can effectively boost NAD levels, their absorption and utilization involve complex, interconnected pathways influenced by multiple factors including transporters, enzymes, and gut bacteria, making a simple comparison of their bioavailability more nuanced than previously thought.

Is NMN or NR More Clinically Effective?

An image of a doctor comparing NMN and NR

Both NMN and NR promise to boost your cellular energy and longevity, but which one delivers better results where it matters most – in clinical studies? Let’s examine the evidence.

Clinical Scorecard for NR

Safety Profile in Human Trials: In a randomized, double-blind, placebo-controlled trial involving 1000 mg/day of NR supplementation for six weeks, participants reported no significant adverse events, indicating a favorable safety profile⁹ (Baur et al., 2019). Another study found that NR was well tolerated at doses up to 3000 mg/day without serious side effects.¹⁰
NAD+ Elevation Capabilities: Research demonstrates that NR supplementation can significantly elevate NAD+ levels in human subjects. One study reported a ~60% increase in NAD+ concentrations after just six weeks of NR¹¹ supplementation. Another trial showed that a single dose of NR increased NAD+ levels within hours,¹² confirming its rapid bioavailability.
Beneficial Outcomes: Clinical trials have shown that NR supplementation leads to improved metabolic health markers¹³, including enhanced insulin sensitivity and reduced blood pressure. Participants in one study exhibited improvements in physical performance, with a notable increase in walking distance during a six-minute walk test after NR supplementation. Another study indicated improvements in lipid profiles and overall cardiovascular health¹⁴ following NR intake.

Clinical Scorecard for NMN

Safety Profile in Human Trials: NMN has demonstrated a strong safety profile in clinical trials. A study involving 250 mg/day of NMN over 12 weeks reported no significant adverse effects among participants¹⁵, indicating it is well tolerated. Another trial with doses up to 900 mg/day also confirmed the absence of serious side effects, further supporting its safety¹⁶.
NAD+ Elevation Capabilities: NMN supplementation has been shown to effectively elevate NAD+ levels in humans. In one human clinical trial, participants taking NMN experienced significant increases in blood NAD+ concentrations at both day 30 and day 60 of supplementation¹⁷. Another study found that NMN doses as low as 300 mg/day could lead to substantial increases in NAD+ levels compared to placebo.¹⁸
Beneficial Outcomes: Participants in NMN clinical trials have shown improvements in physical performance metrics, such as increased walking distance during exercise tests¹⁹. NMN has also been associated with better metabolic health indicators, including reduced arterial stiffness and improved cardiovascular function²⁰.

In sum, both precursor molecules have proven their worth in the clinical arena – they just might suit different individuals based on specific health goals and preferences.

Choosing Between NMN and NR Supplements

With an understanding of the differences between NMN and NR, we now face a common question: which one should you choose as a dietary supplement?

While both molecules ultimately raise NAD levels, their distinct cellular uptake mechanisms and tissue preferences can lead to varying individual responses. Let’s explore the specific advantages of each approach, comparing NMN with NR, and why some advocate for using both together.

The Case for Nicotinamide Riboside

NR has established itself as a well-researched NAD+ precursor with an impressive track record of human clinical trials supporting its safety and efficacy. As a smaller molecule than NMN, NR may have advantages in terms of cellular uptake in certain tissues, particularly in the brain and nervous system. Its metabolism is well-understood, with specific transporters identified in various cell types, and it has demonstrated promising results in studies focused on cognitive function, muscle performance, and metabolic health.

For those seeking a thoroughly studied option with a clear safety profile and established manufacturing processes, NR represents a compelling choice.

The Case for NMN Supplements

NMN supplements offer potential advantages in certain cellular contexts, particularly in tissues that express specific NMN transporters like the Slc12a8 transporter found in the small intestine. Some researchers believe that because NMN is just one step away from becoming NAD+ (whereas NR requires an additional conversion step), it may provide more direct benefits in certain tissues.

Recent human studies have shown promising results for NMN in areas such as muscle strength, endurance, and cardiovascular health, making it an attractive option for those focused on physical performance and metabolic enhancement.

The Case for Taking Both Together

A combination approach incorporating both NMN and NR may offer the most comprehensive strategy. Different tissues and cells throughout the body may preferentially utilize one precursor over the other, and using both ensures that you’re providing your body with multiple pathways to increase NAD levels.

While no direct comparative studies exist between the two molecules, the complementary nature of their uptake mechanisms and tissue distribution patterns suggests that a dual approach could maximize the potential benefits across various body systems. This strategy, while potentially more costly, provides a more complete approach that accounts for the body’s complex and varied cellular preferences.

This scientifically formulated blend combines precisely dosed NMN and Nicotinamide with bioactive D-Ribose and Creatine to maximize NAD+ production, helping reinvigorate cellular energy production, support healthy aging processes, and optimizing overall vitality.

Is NR Better Than NMN for NAD+?

An image of a pharmacist looking at supplements

The debate over whether NR or NMN is the better choice for boosting NAD+ levels doesn’t have a clear-cut answer, and that’s okay. Both compounds offer unique benefits, each helping to raise NAD+ levels and improve metabolic health and cellular function. Rather than comparing them directly, it might be more useful to see them as complementary allies, each playing a part in supporting overall health.

Ultimately, whether you choose NR, NMN, or both, each offers great potential for improving your health and longevity. When used thoughtfully, they can complement each other, enhancing their benefits and helping you reach your wellness goals.

9 Established NAD+ Precursors You Should Know

Written by Jinfiniti Science on November 22, 2024. Posted in NAD+, NAD, NAD+ Precursors. No Comments on 9 Established NAD+ Precursors You Should Know

NAD+ precursors are the building blocks our bodies use to create nicotinamide adenine dinucleotide (NAD+), a molecule vital for cellular health.

While most articles focus on just a handful of these precursors, scientific research has actually identified nine distinct compounds that can boost NAD+ levels in humans. Each follows its own unique pathway through our cellular machinery, from simple vitamin B3 derivatives to more complex molecules like dihydronicotinamide riboside (try saying that five times fast).

In this comprehensive guide, we’ll explore all nine established NAD+ precursors, examining how each one works and what the latest research reveals about their effectiveness.

Key Takeaways

NAD+ is essential for cellular energy, DNA repair, and hundreds of vital functions, but its levels naturally decline with age, making it crucial to understand how to maintain healthy levels throughout life.
There are nine distinct NAD+ precursors available to humans, ranging from common vitamin B3 derivatives like niacin to advanced compounds like NR and NMN, each with unique pathways and varying degrees of research support.
While all precursors can boost NAD+ levels, their effectiveness varies significantly – compounds like NR and NMN show particularly promising results in clinical studies, with demonstrated benefits for cellular health, muscle function, and aging markers.

What are NAD+ Precursors?

If you’ve been researching ways to increase your NAD+ levels, you’ve likely encountered talk of “NAD boosters” or NAD precursor supplements in health and longevity discussions. But what exactly are these compounds and how do they work?

NAD+ precursors are specific molecules that your body can convert into NAD+ through various biological pathways¹. They can be thought of as raw materials your cells need to manufacture NAD+. While all nine precursors ultimately lead to NAD+ production, they take different routes through your cellular hardware and your body processes each one differently.

These precursors fall into several main categories:

Vitamin B3 derivatives (like niacin and niacinamide)
Advanced compounds (such as NR and NMN)
Amino acids (primarily tryptophan)

Research has shown that supplementing with these precursors can effectively raise NAD+ levels in various tissues, though their efficiency and effects can vary significantly. Some require multiple conversion steps before becoming NAD+, while others follow a more direct path. This distinction becomes particularly important when choosing an NAD supplement, as it can affect both the compound’s potency and how quickly your body can put it to use.

The 9 Known NAD+ Precursors

Each NAD+ precursor represents a unique pathway to cellular energy production, with its own set of advantages and characteristics. These nine molecules form the complete family of established NAD+ precursors.

Nicotinamide Riboside (NR)

First discovered in milk and later identified as a vitamin B3 analog, NR has become a leading NAD+ precursor in longevity research. It follows the NRK pathway, where it’s phosphorylated by NRK1/2 enzymes to form NMN before conversion to NAD+. This efficient pathway, combined with excellent oral bioavailability and ability to cross cell membranes, has made NR very attractive for NAD+ enhancement.

Key Findings:

NR supplementation significantly increased blood NAD+ concentrations in older adults with MCI by approximately 2.6-fold (or 160%) compared to placebo²
NR supplements boost NAD+ levels by an impressive 60% in healthy adults, according to rigorous clinical research³
NR shows an excellent safety profile with no serious side effects even at high doses of 2000mg daily⁴
Early research suggests NR can reduce key inflammatory markers in heart failure patients⁵
NR supplementation appears to increase muscle-repairing satellite cells in human studies⁶

Nicotinamide Mononucleotide (NMN)

Identified as a key NAD+ intermediate in the 1960s, NMN is the direct precursor to NAD+ in the salvage pathway. While initially thought to require conversion to NR before entering cells, the 2019 discovery of the Slc12a8 transporter revealed a direct cellular uptake mechanism. Just one enzymatic step away from becoming NAD+, NMN has shown remarkable promise in aging research.

Key Findings:

NMN supplements are proven safe in humans at doses up to 900mg daily with no serious side effects⁷
Clinical studies consistently show NMN effectively boosts blood NAD+ levels, with higher doses yielding stronger increases⁸
Older adults taking NMN demonstrated measurable improvements in walking distance compared to placebo groups⁹
After 12 weeks of NMN supplementation, elderly men showed meaningful gains in grip strength and walking speed¹⁰
While placebo groups continued aging normally, NMN-treated groups showed no increase in biological age markers over a study period¹¹

Nicotinic Acid (NA) / Niacin

Discovered in 1937 by Conrad Elvehjem, niacin was the first NAD+ precursor used therapeutically. It follows the Preiss-Handler pathway, requiring three enzymatic steps to become NAD+. This classic pathway remains significant today, though the characteristic “niacin flush” – caused by prostaglandin release – can limit its practical use.

Key Findings:

A massive meta-analysis of 119 trials with 35,760 participants showed niacin alone could reduce cardiovascular events¹²
Niacin can slash total cholesterol by 25%, LDL by 15%, triglycerides by 50%, while uniquely boosting good HDL cholesterol by up to 35%¹³
When combined with statins, niacin therapy was proven via MRI to actually reverse arterial plaque buildup¹⁴
A landmark 15-year study found niacin reduced mortality by 11% in heart attack survivors (p=0.0004)¹⁵

Nicotinamide (NAM) / Niacinamide

The most abundant form of vitamin B3 in nature, NAM enters the salvage pathway through conversion to NMN by NAMPT, the rate-limiting enzyme in NAD+ biosynthesis. First isolated in 1935, this flush-free precursor compound is both widely available and well-tolerated.

Key Findings:

Taking 500mg nicotinamide twice daily reduced new skin cancer formation by 23% in high-risk patients¹⁶
Nicotinamide lowered pre-cancerous skin lesions (actinic keratoses) by up to 20% over a 12-month period¹⁷
Nicotinamide helps repair DNA and preserve skin immunity by preventing UV radiation from depleting cellular energy¹⁸
In glaucoma patients, nicotinamide combined with pyruvate showed promising improvements in visual field tests¹⁹
Clinical trials have consistently shown nicotinamide to be safe and well-tolerated, even at high doses²⁰

Tryptophan (Trp)

This essential amino acid was found to contribute to NAD+ production in the early 1950s. Tryptophan follows the de novo pathway, requiring eight enzymatic steps to become NAD+ – the most complex route among all precursors. While not the most efficient path, this discovery highlighted the intricate connection between protein metabolism and NAD+ production.

Key Findings:

Higher tryptophan levels appear critical for nutritional interventions to improve mortality rates in vulnerable patients, with nearly 40% better outcomes in high-tryptophan groups²¹
Tryptophan supplementation at 1+ gram doses may improve sleep quality by boosting melatonin production and sleep duration²²
Higher dietary tryptophan intake significantly reduced depression and anxiety in healthy participants, highlighting its role in mood regulation through serotonin production²³
Research shows tryptophan supplementation can reduce ADHD symptoms and aggressive behavior in children²⁴
Daily intake of ~1 gram tryptophan was linked to a dramatic 60% reduction in migraine risk²⁵

Nicotinic Acid Riboside (NAR)

A lesser-known member of the NAD+ precursor family, Nicotinic Acid Riboside (NAR) follows a distinct metabolic pathway involving nicotinamide riboside kinases (NRK1 and NRK2) before entering the Preiss-Handler pathway. This route to NAD+ production differs from other precursors, suggesting potential unique characteristics. Human studies on NAR remain limited compared to more extensively researched NAD+ precursors like NR and NMN.

Key Findings:

NAR released from cells can be taken up and used as an NAD+ precursor by neighboring cells. Even low micromolar concentrations of NAR were sufficient to maintain viability of cells unable to use other NAD+ precursors
NAR appears to be a more effective NAD+ precursor than nicotinamide riboside (NR) for maintaining cell viability at low concentrations. About 10 times less NAR was required compared to NR to maintain viability of cells treated with an NAD+ biosynthesis inhibitor²⁶

Dihydronicotinamide Riboside (NRH)

One of the newer additions to the NAD+ precursor lineup, NRH has shown impressive efficiency in preclinical studies. This reduced form of NR appears to bypass certain cellular checkpoints, potentially offering a more direct route to NAD+ production. Research is ongoing to fully understand its potential advantages and safety profile.

Key Findings:

NRH is a potent NAD+ booster, increasing cellular NAD+ levels by 2.5-10 fold over control values within just 1 hour of administration²⁷
In obese mice, 7 weeks of NRH supplementation dramatically improved metabolism by enhancing pancreatic function, insulin sensitivity, and fat tissue health through elevated NAD+ and sirtuin activation²⁸
While promising for metabolism, NRH may have an inflammatory dark side – it can trigger inflammation in immune cells called macrophages through specific cellular pathways²⁹

Reduced Nicotinamide Mononucleotide (NMNH)

An image of an old woman consulting to doctors.

The most recently identified precursor, NMNH represents a reduced form of NMN that can be directly converted to NADH by NMNAT. This unique pathway, discovered through metabolic studies, potentially offers advantages in NAD+ enhacement, though research is still in early stages.

Key Findings:

NMNH effectively raises NAD+ levels up to 7x in cells, showing enhanced potency compared to traditional NMN supplementation³⁰
While both compounds boost NADH production, NMNH achieves 2.5x baseline levels in cellular studies with particularly strong tissue penetration³¹
NMNH demonstrates unique metabolic effects and growth regulation properties while maintaining a good safety profile at high doses³²

Dihydronicotinic Acid Riboside (NARH)

Discovered alongside other reduced forms of NAD+ precursors, NARH represents another recently identified pathway to NAD+ biosynthesis. This reduced form of NAR enters the Preiss-Handler pathway through a unique mechanism, potentially offering another efficient route to NAD+ production. While research is still emerging, initial studies suggest it may have distinct advantages in certain cellular conditions.

Key Findings:

Researchers discovered NARH, a new NAD+ precursor that works in liver cells, expanding our toolkit for boosting cellular metabolism³³
When combined with NR, NARH creates a powerful synergistic effect that raises NAD+ levels higher than other precursor combinations³⁴

Choosing a High Quality Turmeric Supplement: Buyer’s Guide

Written by Jinfiniti Science on November 19, 2024. Posted in Turmeric/Curcumin. No Comments on Choosing a High Quality Turmeric Supplement: Buyer’s Guide

Your turmeric supplement could be a waste of money.

Harsh? Perhaps. But here’s the truth: not all turmeric supplements are created equal. In fact, many popular brands contain such low-quality ingredients that your body can barely absorb them.

For over 4,000 years, turmeric has been revered in traditional medicine. Today, modern science confirms what ancient healers knew all along – this golden spice packs serious health-promoting power.

But here’s the catch.

As turmeric supplements flood the market, consumers face a bewildering array of choices. Confusing labels. Misleading claims. And prices that range from suspiciously cheap to eye-wateringly expensive.

How do you cut through the noise and find a supplement that actually works?

In this curcumin extract buying guide, you’ll discover:

The common red flags that leave you with an ineffective or, worse, harmful supplement – and how to avoid them.
The four critical factors that separate premium turmeric supplements from worthless pills.
The exact combination of ingredients, dosages, and extraction methods that maximize absorption and effectiveness.
The most bioavailable turmeric supplement on the market.

Health Benefits of Turmeric and Curcumin

Ever wondered why turmeric has a golden color? The same compounds responsible for that vibrant hue also deliver powerful health benefits.

Turmeric root contains a family of active compounds called curcuminoids. The star of the show? Curcumin. This remarkable compound makes up about 2-5% of turmeric and acts as a potent antioxidant and anti-inflammatory agent.

Modern science has extensively studied curcumin’s effects on health. Here’s what the research reveals:

Curcumin targets multiple steps in the inflammatory pathway and matches the effectiveness of some anti-inflammatory drugs – without the harsh side effects¹.
Clinical trials have demonstrated curcumin’s ability to reduce joint tenderness, improve flexibility, decrease inflammatory markers and support cartilage health².
Curcumin can cross the blood-brain barrier, increase BDNF (brain-derived neurotrophic factor)³, support memory and focus, and help maintain cognitive function with age⁴.
Curcumin supports healthy blood pressure⁵, improves blood vessel function⁶, and maintains healthy cholesterol levels⁷.
Curcumin neutralizes harmful free radicals, boosts your body’s own antioxidant enzymes and helps protect cells from oxidative stress⁸.

However, your kitchen turmeric and a high-quality supplement are worlds apart. The powdered turmeric you find on most grocery shelves contains just 2-5% curcumin with poor absorption rates by the body, requiring large amounts for therapeutic effects, making it best suited for adding flavor to food.

What’s more, curcumin is notoriously difficult for your body to absorb. In fact, studies show that plain curcumin gets metabolized and eliminated before it can deliver its benefits.

Hence the importance of choosing turmeric supplements that maximize the absorption of curcumin.

Red Flags When Buying Turmeric Supplements

The truth about turmeric supplements lies in the details. Here are the top warning signs to watch for that signal poor quality and potentially misleading products.

The Mystery of “Proprietary Blends”

When you see “proprietary blend” on a label, proceed with caution. Here’s why:

Manufacturers don’t disclose individual ingredient amounts
You can’t verify if you’re getting therapeutic doses
The first ingredient might be present in meaningful amounts, but the rest could be mere sprinkles
It’s often a tactic to hide low doses of expensive ingredients

What to Do Instead: Look for supplements that clearly list the amount of each ingredient, especially the curcuminoid content.

Suspiciously Low Prices

That bargain-bin turmeric supplement? It’s probably too good to be true. Quality turmeric supplements are expensive to produce because they require:

High-grade raw materials
Standardized extraction processes
Third-party testing
Quality control measures

If a month’s supply costs less than $20, question what corners were cut to achieve that price.

Industry Insight: High-quality turmeric extract with 95% curcuminoids is expensive to produce. When you factor in other active ingredients and production costs, extremely low prices simply don’t add up.

Missing or Vague Standardization Information

Quality supplements proudly display their standardization percentages. Red flags include:

No mention of curcuminoid percentage
Unclear extract ratios
Missing potency information
Vague terms like “high-strength” without specifics

What to Look For: Clear statements like “standardized to 95% curcuminoids” or “contains 1000mg of turmeric extract (95% curcuminoids).”

The Filler Trap

Check the “Other Ingredients” section carefully. Avoid supplements loaded with:

Artificial colors
Chemical preservatives
Unnecessary binding agents
Cheap bulking agents like maltodextrin
Silicon dioxide in large amounts

Best Practice: Look for products with minimal necessary ingredients and vegetable-based capsules.

What to Look For When Choosing a Turmeric Supplement

Choosing the right curcumin supplement doesn’t have to be complicated. Armed with the right knowledge, you can quickly identify high-quality products that deliver real results.

Here are the three essential factors that separate premium supplements from ineffective ones.

Curcuminoid Content

A high-quality turmeric supplement should contain extract standardized to 95% curcuminoids, with the amount clearly stated on the label. Research shows this concentration provides the most powerful anti-inflammatory and antioxidant benefits.

Bioavailability Enhancers

Even the highest-quality curcumin is useless if your body can’t absorb it. That’s why leading supplements include bioavailability enhancers like black pepper extract (standardized to 95% piperine), which can increase absorption by up to 2000%⁹.

Dosage Considerations

Research indicates that the sweet spot for turmeric supplementation is 1000-1500mg of standardized extract per day, typically divided into 1-2 doses. More isn’t necessarily better – studies show that doses above 2000mg per day don’t provide additional benefits and may increase the risk of mild side effects.

A high-quality turmeric supplement should check all these boxes:

✓ 95% standardized curcuminoid extract

✓ Bioavailability enhancers included

✓ 1000-1500mg daily dose

✓ Clear labeling of all ingredients

What Form of Curcumin is Best?

Curcumin formulated with black pepper extract (BioPerine) is considered the most effective form, as it significantly improves absorption compared to standard supplements.

When is the Best Time to Take Curcumin?

For optimal absorption, take curcumin supplements with a meal containing healthy fats, as curcumin is fat-soluble and needs dietary fat to be properly absorbed.

How Does Curcumin Help with Inflammation?

Curcumin works by blocking key inflammatory molecules like NF-kB and COX-2, while also acting as a powerful antioxidant that neutralizes free radicals in the body.
