Curcumin or Turmeric Root: Which Fights Inflammation Best?

Written by Jinfiniti Science on February 2, 2025. Posted in Inflammation, Turmeric/Curcumin. No Comments on Curcumin or Turmeric Root: Which Fights Inflammation Best?

Inflammation reveals itself through familiar sensations—joint stiffness, muscle soreness, localized warmth. Beneath these surface symptoms, molecular processes like NF-kB activation and COX-2 enzyme production drive cellular responses that influence long-term health outcomes.

Two natural substances frequently studied for their anti-inflammatory properties are turmeric and its primary active compound, curcumin. While derived from the same rhizome, the two are not identical in their effects or applications.

The choice between whole-plant preparation and isolated compounds depends on bioavailability requirements, symptom severity, and individual metabolic factors. The latest research indicates curcumin’s potency in acute inflammatory scenarios, while turmeric’s broader phytochemical profile may offer gentler support for chronic conditions .

This article explores how these golden compounds work differently to combat inflammation and which might be the better choice for your specific situation.

Key Takeaways:

Turmeric is the whole spice containing multiple beneficial compounds, while curcumin is just one active ingredient making up 2-8% of turmeric powder—along with other valuable compounds like essential oils and polysaccharides.
Both turmeric and curcumin have poor bioavailability on their own, but absorption can be dramatically improved by combining them with black pepper (containing piperine) or fats, or through modern delivery methods like nanoformulations.
Curcumin provides strong anti-inflammatory benefits by blocking specific cellular pathways, while whole turmeric offers a broad spectrum of anti-inflammatory effects through its diverse compound profile.
Research shows both substances are effective for managing various inflammatory conditions, with curcumin demonstrating comparable effectiveness to NSAIDs but with fewer side effects, and having a strong safety profile.

Aren’t Turmeric and Curcumin the Same Thing?

Turmeric and curcumin appear side by side on supplement labels, in research papers, and across health blogs—but these seemingly identical twins have some differences that matter for your health.

Turmeric is a spice derived from the rhizome (underground stem) of the Curcuma longa plant¹, commonly used in cooking, especially in Asian cuisines. It’s that bright yellow spice you’ve probably seen from curry dishes. Inside turmeric is curcumin, the active ingredient responsible for its yellow color.²

Turmeric rhizome is composed of several bioactive compounds, including curcuminoids, essential oils, and polysaccharides. The curcuminoid family primarily comprises curcumin, demethoxycurcumin, and bisdemethoxycurcumin, with curcumin being the most abundant and studied.³

On average, curcumin represents about 2–8% of most turmeric powders.⁴ Imagine, that is like having a glass of juice that’s 92-98% water. In addition to curcumin, turmeric contains other beneficial compounds such as demethoxycurcumin and volatile oils like turmerone.

These compounds work together to provide a broad spectrum of health benefits. While curcumin is often isolated in supplements for its potent effects, whole turmeric contains a range of other beneficial polyphenols that may contribute to its overall health impact.

It’s worth noting that a typical serving of turmeric powder (about 3 grams or a dessert spoon) contains approximately 30–90 mg of curcumin. This relatively low concentration in whole turmeric is one reason why supplements often contain concentrated curcumin extracts.

The Bioavailability Challenge

Turmeric is packed with beneficial compounds, but there’s a significant hurdle: your body struggles to absorb them efficiently. Most of turmeric’s active components, particularly curcumin, pass through your system with minimal absorption, limiting their potential benefits.

This challenge arises because curcumin is poorly soluble in water⁵ and is rapidly metabolized and eliminated by the liver and intestines.⁶ These factors significantly reduce the amount of curcumin that enters your bloodstream in an active form.

For centuries, traditional preparation methods have provided simple but effective solutions to improve curcumin’s absorption. Recipes often pair turmeric with black pepper, which contains piperine—a compound that can enhance curcumin absorption by up to 2,000%.⁷ Other traditional methods include combining turmeric with fats (as in oil-based dishes or golden milk), which help dissolve curcumin and make it more bioavailable.

Modern science has built on these traditional practices by developing advanced strategies to overcome curcumin’s bioavailability issues. One promising approach involves nanoformulations⁸—delivering curcumin in ultra-small particles or encapsulated forms designed to improve its solubility and absorption.

Research published in the journal Antioxidants suggests that the latest generation of curcumin nanoformulations can increase free curcumin bioavailability in plasma by more than 100-fold⁹, resulting in improved absorption.

Although incorporating turmeric into your diet is beneficial, accessing the full spectrum of curcumin’s therapeutic properties likely requires a more targeted approach.

Turmeric vs. Curcumin for Inflammation

Understanding the difference between turmeric and curcumin is essential when looking to fight inflammation, as both are widely praised for their anti-inflammatory properties. If you’re already taking turmeric and curcumin supplements or just exploring your options, knowing how each compound works can help you achieve better results.

How Curcumin and Turmeric Fight Inflammation

Curcumin blocks inflammation through multiple cellular pathways, particularly by inhibiting NF-κB, MAPK, and JAK/STAT signaling.¹⁰ This action reduces the production of key inflammatory molecules, including specific cytokines (IL-1β, IL-6, TNF-α) and enzymes (COX-2, iNOS), while helping regulate immune cell balance between pro-inflammatory and anti-inflammatory responses.

Turmeric root’s comprehensive anti-inflammatory effects come from its diverse bioactive compounds, including essential oils and turmerones alongside curcumin. These compounds work together to enhance the body’s antioxidant defenses, reduce oxidative stress, and modulate immune cell function, providing a multi-targeted approach to managing inflammation.¹¹

Anti-Inflammatory Benefits Compared

Curcumin supplementation offers potent anti-inflammatory benefits—validated by an umbrella meta-analysis of 5,870 participants showing significant drops in C-reactive protein (CRP), a key inflammation biomarker.¹² The effects of curcumin were not strictly dose- or time-dependent, with benefits observed across a range of doses (300–1900 mg/day) and durations (4.5–10.5 weeks).

Whole turmeric root employs a more holistic strategy to address inflammation. Its natural blend of compounds—curcumin working alongside turmerones and polysaccharides—creates a balanced anti-inflammatory response. This mirrors traditional medicine’s long-standing preference for using the complete root.

This biological teamwork showed practical benefits in elite footballers consuming a 60 mL turmeric drink twice daily, with 16.4% greater muscle soreness reduction and significantly lower CRP levels compared to controls.¹³

While both turmeric and curcumin offer valuable anti-inflammatory effects, their mechanisms and applications differ significantly. Curcumin provides concentrated benefits for reducing specific inflammatory markers, while whole turmeric presents a broader spectrum of action through its diverse phytochemical composition.

Curcumin’s Effectiveness for Specific Conditions

Research demonstrates that concentrated curcumin exhibits particularly strong therapeutic potential for inflammatory and autoimmune conditions compared to turmeric alone.

Arthritis

Studies about the effect of curcumin¹⁴ on rheumatoid arthritis have been shown to reduce joint pain and improve mobility. In some cases, it has performed as effectively as traditional NSAIDs, but with fewer of the associated side effects.

Inflammatory Bowel Disease (IBD)

Curcumin can help manage symptoms and even induce remission in IBD patients¹⁵, offering a potential therapeutic option. Its anti-inflammatory and antioxidant properties help in reducing inflammation and oxidative stress in the gut.

Autoimmune Diseases

Curcumin has shown benefits in conditions like systemic lupus erythematosus, psoriasis, and sclerosis by reducing symptoms and slowing disease progression.¹⁶ It modulates immune responses and reduces inflammatory mediators, which are crucial in autoimmune conditions.

Comparative Effectiveness with Traditional NSAIDs

Research suggests curcumin is as effective as NSAIDs (nonsteroidal anti-inflammatory drugs), such as ibuprofen, for managing pain and inflammation. Unlike NSAIDs, however, curcumin comes with fewer risks of gastrointestinal issues or long-term complications.¹⁷

Potential for Long-Term Inflammatory Management

Curcumin has been shown to be safe in multiple human trials, even at high doses. Studies have reported no toxicity at doses up to 12 grams per day over a period of three months.¹⁸ Other trials using doses ranging from 1125 to 2500 mg per day also found curcumin to be safe, with no significant adverse effects reported.¹⁹

Further Health Benefits of Turmeric and Curcumin

Research suggests that both turmeric and curcumin may share beneficial effects across several key health areas, though most clinical studies have focused on curcumin as the primary active compound.

Here are some of the promising benefits supported by scientific evidence:

Antioxidant Properties: Curcumin, in particular, is known for its ability to neutralize free radicals, which can help reduce cellular damage and slow down aging.²⁰

Antifungal and Antibacterial Effects: Curcumin has demonstrated antibacterial effects against both Gram-positive and Gram-negative bacteria, including Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa.²¹ Curcumin also exhibits antifungal activity against various fungi, including those causing dermatophytosis and candidiasis.²²

Brain Health: Curcumin may help enhance brain-derived neurotrophic factor (BDNF), which is a protein linked to improved cognitive function and a reduced risk of neurodegenerative disorders like Alzheimer’s.²³

Cardiovascular Health: Both turmeric and curcumin also support cardiovascular function by enhancing vascular endothelial function, boosting nitric oxide bioavailability, and reducing oxidative stress²⁴, which supports overall heart health.

Metabolic Support: Curcumin is also reported to improve insulin sensitivity, regulate blood sugar levels, and combat obesity-related inflammation.²⁵

Potential Anti-Cancer Effects: Research suggests curcumin may slow cancer cell growth and inhibit cancer cell development²⁶ through its anti-inflammatory and antioxidant activities.

Should You Choose Turmeric or Curcumin?

For acute inflammatory conditions or specific therapeutic needs, concentrated curcumin supplements typically offer the most potent benefits, especially when enhanced with compounds like piperine. The higher concentration and focused action make curcumin ideal for managing targeted health concerns like arthritis or intense physical recovery.

Those seeking gentle, long-term inflammatory support may find better value in quality turmeric supplements or dietary incorporation. Whole turmeric’s diverse compound profile provides a broader spectrum of benefits that work together to support overall wellness and address chronic inflammation.

A Precision Approach to Managing Inflammation

Inflammation manifests differently in each person, influenced by genetics, lifestyle, and environmental factors. What works for general wellness support might need careful adjustment for specific therapeutic goals. This is where a precision-based approach becomes invaluable.

Modern biomarker testing can measure your unique inflammatory status through key indicators like C-reactive protein (CRP), pro-inflammatory cytokines, and other cellular markers. This data creates a clear baseline for understanding your body’s specific needs and helps track how well anti-inflammatory interventions are working.

For optimal results, consider these evidence-based steps:

Measure your baseline inflammatory markers through a cellular inflammation test
Choose a high-quality supplement that matches your specific needs
Monitor your progress with regular biomarker assessment
Adjust your approach based on measurable outcomes

When choosing a turmeric or curcumin supplement, look for products that maximize bioavailability through proven methods like piperine inclusion or advanced delivery systems.

Our premium turmeric curcumin supplement Extra Strength Turmeric+ combines high-potency turmeric extract (95% curcuminoids) with complementary compounds like Boswellia, ginger root, and quercetin, enhanced by black pepper extract for optimal absorption.

While turmeric and curcumin supplements have excellent safety profiles, certain situations require careful consideration. Those taking anticoagulant medications, managing bleeding disorders, or preparing for surgery should consult healthcare providers before use.

Through this measured, data-driven approach to inflammation management, you can move beyond generalized supplementation to achieve more targeted, personalized results.

9 Natural Senolytic Supplements You Need to Know

Written by Jinfiniti Science on January 27, 2025. Posted in NAD+, NAD, Piperine, Quercetin, Senescence, Turmeric/Curcumin. No Comments on 9 Natural Senolytic Supplements You Need to Know

There’s growing interest in using natural compounds to support healthy aging, and it’s no surprise. People are increasingly looking for ways to age gracefully without relying solely on synthetic drugs.

As of 2025, age-related chronic diseases account for the majority of deaths worldwide¹, with chronological age being the major risk factor. This underscores the critical need for interventions that can slow the aging process and reduce disease burden. Senolytics present a promising strategy to increase healthspan by targeting senescent cells that accumulate in disease-related tissues

Let’s dive into the top 9 natural senolytic supplements based on the latest research.

Key Takeaways:

Senolytic compounds like quercetin, fisetin, and curcumin help remove senescent cells that cause chronic inflammation and age-related diseases, supporting healthier aging at the cellular level.
Many natural senolytics, found in everyday foods and herbs like green tea and chamomile, can help reduce inflammation, improve tissue health, and even extend lifespan.
Using tools like the AgingSOS® Senescence & NAD Panel lets you measure key biomarkers like senescence burden and NAD+ levels, so you can fine-tune your senolytic supplementation for optimal results and better control over your health.

What Are Natural Senolytics?

Senolytics are compounds that target and clear out senescent cells, also called “zombie cells²” that build up as we age and send out inflammatory signals. By selectively eliminating these cells, senolytics may help reduce inflammation, improve tissue function, and promote healthier aging

Senolytics come in both natural and synthetic forms. According to a 2019 study published in EbioMedicine, pharmaceutical senolytics like Dasatinib have shown strong effects in lab studies but can come with side effects³. On the other hand, natural senolytics like Quercetin are plant-derived compounds found in everyday foods and herbs.

The concept of senolytics emerged around 2015. According to Science Daily, researchers from the Mayo Clinic and Scripps Institute were the first to find compounds capable of selectively eliminating senescent cells⁴. Since then, studies in animals and early human trials have shown promising benefits, particularly for age-related inflammation and tissue repair.

How Senolytics Combat Cellular Senescence

As we age, some of our cells enter a state called senescence, where they stop dividing but don’t die off like they should. These so-called zombie cells linger in tissues, releasing harmful molecules that trigger chronic inflammation and damage surrounding healthy cells⁵. This ongoing inflammation, known as inflammageing, contributes to many age-related diseases, including arthritis and heart disease⁶.

Senolytics target and eliminate these dysfunctional cells, allowing the body to function more efficiently. In fact, compounds like quercetin and fisetin can selectively induce apoptosis (programmed cell death) in senescent cells without harming normal ones⁷.

With their ability to clear out these nefarious cells, senolytics help reduce systemic inflammation, improve tissue regeneration, and support overall longevity.

The 9 Best Natural-Source Senolytic Supplements

Research has identified several plant-derived compounds with senolytic activity that help clear senescent cells that accumulate over time, reduce overall inflammation, and support healthy aging.

Quercetin and Fisetin

Quercetin and fisetin are two of the most well-researched natural senolytics known for their ability to help clear senescent cells and reduce inflammation. Found in fruits and vegetables like apples, onions (quercetin), and strawberries (fisetin), these flavonoids have been shown to promote cellular health and longevity⁸.

A study published in the International Journal of Molecular Sciences found that fisetin, in particular, may be one of the most potent natural senolytics. This senolytic selectively eliminates senescent cells without harming healthy ones.⁹

Moreover, research suggests that quercetin and fisetin work even better together¹⁰, enhancing their senolytic effects.

This synergy is a key feature of our SenoAid™ senolytic supplement complex designed to maximize these benefits. This supplement is even fortified with bromelain enzymes and green tea extract, along with piperine for optimal absorption.

Epigallocatechin Gallate (EGCG)

Epigallocatechin gallate (EGCG) is a major polyphenolic compound found in green tea that has been studied for its potential senolytic properties, which involve the selective elimination of senescent cells.

The senolytic properties of EGCG are highlighted by its ability to induce cell death in senescent cells. EGCG suppresses the accumulation of anti-apoptotic proteins and modulates key signaling pathways, facilitating the removal of these dysfunctional cells, which could be beneficial in developing anti-aging therapies¹¹.

Green tea is the richest natural source of EGCG, making it a simple addition to any longevity-focused routine. However, taking too much can strain the liver in some people¹², so it’s important to consume it in moderation.

Piperlongumine

Piperlongumine is a bioactive compound found in the fruits and roots of long pepper. According to a study published in Scientific Reports, Piperlongumine selectively targets and eliminates senescent cells by increasing oxidative stress within them while sparing healthy cells.¹³ This makes it an effective natural senolytic in reducing age-related inflammation and improving tissue function.

Since Piperlongumine works by increasing oxidative stress to target senescent cells, taking too much could also affect healthy cells¹⁴ if not used properly. While more research is needed to know its long-term safety, early studies suggest it could be a helpful tool for supporting healthy aging.

Curcumin

Curcumin is the active compound in turmeric. It has long been studied for its anti-inflammatory and senolytic effects. In a study published in Frontiers, researchers found that curcumin can clear senescent cells by targeting inflammation and oxidative stress.¹⁵ Curcumin helps improve tissue health and function, making it a powerful addition to any anti-aging regimen.

When choosing a curcumin supplement, prioritize high-quality, bioavailable formulations. Look specifically for products containing black pepper extract (piperine), which increases absorption by up to 2000%. Without this crucial ingredient, your body will struggle to properly utilize curcumin’s beneficial properties.

Our Extra Strength turmeric curcumin supplement is an excellent option if you want to tap into curcumin’s senolytic benefits. Its scientifically validated formula, combined with absorption-enhancing ingredients, is designed to reduce inflammation and support healthy aging.

Apigenin

Apigenin is a natural flavonoid found in chamomile. It has long been known for its ability to fight inflammation, protect against cell damage, and stop the growth of abnormal cells.

The flavonoid works by blocking certain signals in the body that cause low-grade inflammation¹⁶, which causes many age-related diseases (ARDs), such as arthritis, renal dysfunction, and neurodegenerative diseases.

The research indicates that normal dosages are well-established as safe and effective. While the long-term effects of high doses require further study, this should not deter use. Chamomile, whether consumed as a tea or supplement, is a compound that may significantly benefit cellular health.

Resveratrol

Resveratrol is a natural compound found in grapes, berries, red wine, peanuts, and cocoa. It helps activate sirtuins, proteins that manage cellular health by controlling aging, inflammation, and metabolism. Resveratrol also modulates cell cycles and multiple pathways involved in cell growth, apoptosis, and senescence.¹⁷

The Senescence-Associated Secretory Phenotype (SASP) is a hallmark of cellular senescence. Resveratrol has been shown to significantly decrease the expression of SASP-related factors¹⁸, which may help mitigate the inflammatory and tissue-damaging effects associated with senescent cells.

However, as with any supplement, moderation is important. At high concentrations, resveratrol can become toxic to cells¹⁹, potentially causing damage rather than providing benefits.

Oleuropein and Hydroxytyrosol

Image of olive oil containing oleuropein

Oleuropein (OLE) and hydroxytyrosol (HT) are two powerful compounds found in olive oil. These natural antioxidants help to protect cells from oxidative stress and inflammation²⁰, both of which contribute to aging and chronic diseases.

Oleuropein has been found to support the elimination of senescent cells²¹ while hydroxytyrosol can help enhance mitochondrial function²², contributing to healthier, more resilient cells.

OLE and HT are easy for the body to absorb, but how well you process them can vary based on what else you’re eating and your overall health picture. While olive oil is an excellent daily staple, supplements may help you reach optimal levels.

What’s the Difference Between Biological and Chronological Age?

Written by Jinfiniti Science on January 26, 2025. Posted in Longevity, At-Home Testing, DNA Damage, Epigenetic, Inflammation, Premature Aging.

The number of candles on your birthday cake tells one story, but your body might be telling another.

While we conventionally measure age by the years we’ve lived, scientists now understand that our bodies can age at remarkably different rates from our chronological age. This disconnect between “calendar age” and “biological age” isn’t just an academic curiosity—it could be the key to understanding why some people experience vibrant health well into their later years while others face age-related challenges much earlier.

Consider two 50-year-olds: one might have the biological profile of a 40-year-old, while another’s cellular markers might suggest they’re closer to 60. This disparity holds profound implications for how we think about aging, health optimization, and the potential to influence our biological trajectory.

The question isn’t just how old you are—it’s how old your body thinks it is.

Key Takeaways:

Biological age reflects your body’s health at the cellular level while chronological age simply counts years lived.
Scientists measure biological age using blood tests, epigenetic clocks, and other markers to assess overall health status.
Diet, exercise, sleep, environment, stress, and social connections all significantly influence how quickly our cells age.
Research suggests biological age may be partially reversible through lifestyle changes focused on diet, exercise, and stress management.

Biological Age vs. Chronological Age: What’s the Difference?

Your chronological age is the number of years you’ve been alive, while your biological age reflects the physiological condition and health of your cells.

These two measures of aging tell different stories about our bodies. While they’re interconnected, understanding their distinct characteristics helps reveal why some people age differently than others.

What is Chronological Age?

Chronological age is simply the number of years you’ve been alive. It’s a straightforward measurement that starts at birth and increases predictably with each passing year, serving as a reliable administrative marker for everything from school enrollment to retirement planning.

What is Biological Age?

Biological age reflects your body’s actual physiological state—how well your cells, tissues, and organ systems are functioning compared to established age norms. It’s determined by measuring specific biomarkers that indicate how rapidly your body is aging at a molecular level.

This biological clock can tick faster or slower based on genetics, lifestyle choices, environmental exposures, and even psychological factors, making it a dynamic measure of your overall health status rather than a fixed number.

How is Biological Age Determined?

Scientists determine biological age through multiple cellular and molecular markers that reveal how quickly our bodies are aging. Each technique has benefits and limitations.

Many researchers combine these approaches for a full picture of biological aging.

Telomeres and Cellular Aging

Telomeres are repetitive sequences at the ends of chromosomes that shorten each time a cell divides. Over many cycles, this loss can limit a cell’s ability to divide, which affects tissue renewal and raises the risk of age-related illness¹.

When they reach a critically low length, cells often stop dividing or self-destruct, leading to senescence and poorer organ function². Some researchers view telomere length as an indicator of biological age, since it can reflect life stress and cellular turnover.

Factors such as inflammation and oxidative stress can accelerate telomere attrition and intensify cellular aging. Telomere-focused interventions are a topic of growing study, with hopes they may slow decline or reduce susceptibility to age-linked disorders³.

Epigenetic Changes and DNA Methylation

Epigenetics refers to chemical marks on DNA that shift how genes work without changing the DNA sequence.

One key mark is DNA methylation, which happens when certain enzymes add small molecules to specific DNA points. These marks can switch genes on or off and often build up over a lifetime⁴.

Scientists observe that the patterns of DNA methylation tend to follow a set course with age. By studying those patterns, researchers can estimate how “old” tissues appear biologically. This is called an epigenetic clock⁵.

These clocks rely on groups of CpG sites, which are stretches of DNA where cytosine and guanine sit next to each other⁶. At those sites, the amount of methylation can reflect the body’s aging pace. If someone’s epigenetic age is higher than expected, it may signal a faster rate of aging.

Metabolic Health Markers

Metabolic markers can reveal how well the body controls energy, manages stress, and maintains normal function⁷. Common markers include fasting glucose, cholesterol levels, and certain hormones that regulate growth and repair.

Researchers have found that changes in these markers can predict whether a person’s biological age is higher or lower than the average for their birth year. For example, higher fasting glucose or cholesterol may point to a faster rate of aging, and balance in these markers can coincide with slower aging⁸.

Body composition plays a role. More lean muscle mass and less visceral fat often line up with a younger biological profile, linked to lower risk factors for heart disease and diabetes⁹.

Breathing tests, grip strength, and measures of inflammation can be folded in too, giving a more detailed view of a person’s metabolic age. Experts sometimes combine these findings into an index that can gauge health status and signal early warning signs.

Inflammation Levels

Chronic, low-level inflammatory biomarkers, such as C-reactive protein, interleukin-6, and tumor necrosis factor-α, often rise with age, reflecting a state sometimes called inflammageing¹⁰.

These markers help researchers gauge how a person’s body deviates from expected health patterns. Elevated measures tend to indicate a faster pace of biological aging and a higher likelihood of adverse outcomes¹¹.

Scientists sometimes combine multiple markers into a single score to capture overall inflammatory burden, and this combined approach can predict mortality more reliably than individual markers or certain epigenetic clocks¹².

Phenotypic Markers

Some methods draw on routine tests, such as blood chemistry, heart rate, and blood pressure. These data points are combined into a single measure called phenotypic age, designed to mirror a person’s risk for age-related conditions and mortality¹³.

Frailty Scores

Clinicians sometimes use frailty indices to capture functional decline, using tests of muscle strength, mobility, and other assessments. This approach looks at how aging impacts day-to-day performance and resilience¹⁴.

6 Factors That Shape Biological Aging

The pace of biological aging isn’t set in stone. Multiple factors work together to influence how quickly or slowly our bodies age at the cellular level.

Infographic of lifestyle factors that influence biological aging

1. Diet

Dietary choices can shape how quickly the body ages. Diets high in sugar or processed foods can raise inflammation and oxidative stress, which can lead to accelerated biological aging.

Research on plant-forward patterns, such as Mediterranean-style eating, suggests that nutrient-dense foods may support slower epigenetic changes, helping cells function at a “younger” level¹⁵.

2. Exercise

In a trial on sedentary older adults, short bursts of high-intensity interval training improved biological age measures by around 3.6 years, suggesting that brief sessions of vigorous movement may reshape gene expression in favor of younger cell behavior¹⁶.

Other research shows that regular exercise helps preserve muscle mass and strength while supporting youthful patterns in muscle biomarkers, which can lower the odds of conditions tied to the aging process.

Studies using transcriptomic analyses also point to an ability of physical activity to reprogram muscle tissue toward more youthful states, reflecting healthier function and resilience across multiple cell pathways¹⁷.

3. Sleep

Research shows that missing out on adequate rest can hasten physical decline. One study found that even one night of disrupted sleep can trigger gene expression patterns linked to cellular aging¹⁸.

Other evidence suggests that partial sleep deprivation in older adults activates processes like DNA damage and inflammation, raising the chance of senescence and disease¹⁹.

In contrast, consistent nights of restful sleep seem to preserve healthier biological markers and may slow increases in age-related risk²⁰. Signs include stable telomere length, stronger immune function, and better cardiometabolic health²¹.

4. Environment

Studies link exposure to pollutants—particulate matter in particular—to faster shifts in markers of aging²².

Fine particles can trigger harmful inflammation and stress on cells. Noise and limited green space may add strain, while cleaner air and access to nature have shown a link to healthier brain and body measures²³.

Researchers have found that early-life and long-term environmental exposures can have lingering effects on epigenetic aging²⁴.

5. Stress

Chronic stress may raise stress hormones and spark inflammatory processes that speed up cellular decline. This can include shortening of telomeres and damaging gene expression patterns linked to aging²⁵.

Emotional resilience and effective coping tools can offset these changes, and people who manage stress well sometimes show slower biological aging despite challenging life events²⁶.

6. Social Connection

Isolation has been tied to higher levels of inflammation, worse clinical markers, and a higher chance of accelerated aging. Conversely, older adults with richer social ties often display healthier biological measures, such as better heart function and slower epigenetic drift²⁷.

Studies suggest that supportive relationships may buffer the body’s stress response, which can help preserve cells and tissues longer²⁸.

How to Measure Your Biological Age

Many people wonder how fast their bodies are aging beneath the surface. Modern research offers fresh ways to assess that rate, stepping beyond a birthday candle count.

Here are the core biological age tests used to calculate your “true” age.

Blood Tests for Biomarkers

Many studies use standard blood tests to track physiological aging by measuring markers linked to metabolism, inflammation, cardiovascular function, and kidney health²⁹.

Common parameters include measures such as cholesterol, albumin, HbA1c, certain globulins, and others that correlate with long-term health. Composite scores from these markers can indicate how an individual’s biology compares with peers of the same chronological age.

Jinfiniti offers three comprehensive AgingSOS® panels to match your needs: our Starter Panel with 16 essential biomarkers, our Advanced Longevity Panel with 22 biomarkers, and our cellular inflammation test that adds cellular senescence markers for the most complete picture of your aging status.

Epigenetic Clocks

Scientists measure DNA methylation at specific sites across the genome to calculate an “epigenetic age” that may differ from chronological age.

Examples include Horvath’s clock and GrimAge, both of which predict lifespan and disease risk. These clocks are trained on patterns of DNA methylation that shift as people grow older³⁰.

A person whose epigenetic clock runs ahead of their chronological age might be aging faster at the cellular level, whereas a slower clock could point to more robust health.

Our AgeRate Epigenetic Age Test analyzes methylation patterns at over 10,000 sites to determine your biological age with high precision.

Telomere Length Tests

Telomeres are protective regions at the ends of chromosomes and get shorter each time a cell divides.

Shorter telomeres suggest cells have undergone more cycles of division and may signal advanced biological aging. Tests typically assess the average telomere length in white blood cells and compare it with population averages³¹.

Emerging Technologies

AI models can analyze diverse health indicators — such as blood biomarkers, lifestyle factors, and medical histories — to estimate biological age with strong accuracy³².

Machine learning algorithms can uncover patterns unrecognized by simpler models. They can also provide individualized explanations of the factors leading to a higher or lower biological age score.

All these methods aim to estimate how your body is faring relative to your birthdate. They often work best when combined, providing a more thorough view of aging at the cellular, molecular, and whole-body levels.

Can You Turn Back the Clock on Biological Aging?

Some research suggests that it may be possible to slow or partly reverse biological age through certain lifestyle habits and medical interventions³³.

Scientists have shown in mouse studies that resetting epigenetic instructions in cells can restore younger function, indicating that aging might be flexible rather than a one-way path³⁴.

In small human trials, participants who modified their diet, supported healthy sleep patterns, exercised, and practiced relaxation methods reduced their measured biological age by a few years within just weeks or months³⁵.

The science behind these approaches is still developing, but studies point toward the promise of lowering biological age by combining regular exercise, a balanced diet, quality rest, and stress management—factors that may keep cells healthier and more youthful over time³⁶.

Embracing Your Biological Age for a Healthy Future

Understanding the gap between your chronological and biological age opens new possibilities for health optimization. More than just a number, biological age provides actionable insights into how lifestyle choices affect your cellular health.

The science of biological age measurement bridges the gap between lifespan and healthspan—helping ensure that additional years of life are matched by sustained vitality and well-being.

How NAD+ and NMN Supplements Impact Female Fertility

Written by Jinfiniti Science on January 24, 2025. Posted in NAD+, Infertility, NAD+ Precursors. No Comments on How NAD+ and NMN Supplements Impact Female Fertility

The clock on your fertility isn’t just ticking—it’s running on cellular batteries. While most women know about the biological clock, few understand the molecular power supply that keeps it running.

Inside each of your eggs lies an intricate network of mitochondria—more than in any other cell type in your body. These cellular powerhouses depend on nicotinamide adenine dinucleotide, a molecule known as NAD+ that orchestrates energy production and DNA repair. The reality of aging brings a steady decline in NAD+ levels, which may compromise egg quality and reproductive potential.

Recent scientific advances point to NMN supplementation as a way to replenish these diminishing NAD+ reserves. Unlike traditional fertility approaches that work indirectly, NMN targets the fundamental cellular processes within egg cells. This breakthrough in cellular science is opening new possibilities for women’s reproductive health—and challenging our assumptions about biological time.

Key Takeaways:

NAD+ levels naturally decline with age in women’s eggs, which significantly impacts fertility since egg cells contain more mitochondria than any other cell type and require substantial energy for proper development and division.
Scientific studies demonstrate that NMN supplementation can help restore NAD+ levels in aging ovaries, leading to improved egg quality, enhanced mitochondrial function, and better reproductive outcomes in research models.
The timing of NAD+ intervention appears crucial, as research indicates that while NMN supplementation can improve various markers of ovarian health, it may be most effective when started before advanced age-related fertility decline occurs.
Regular monitoring of NAD+ levels through testing can help optimize supplementation strategies.

NAD+ Decline and Women’s Fertility

Your eggs demand more energy than any other cells in your body. These remarkable cells house dense networks of mitochondria¹—energy-producing structures that run on NAD+ to fuel the intricate process of reproduction.

A comprehensive review by Liang et al. (2023) synthesized our understanding of NAD+ metabolism’s impact on ovarian aging². As time takes its toll and NAD+ levels decline, a cascade of challenges occur within egg cells:

Mitochondrial energy production falters, compromising cellular function

DNA repair mechanisms slow, leaving genetic material vulnerable

Oxidative stress defenses weaken

Cell division loses its precision

Perrone et al. (2023) identified the culprit: CD38, a protein abundant in ovarian immune cells, that actively depletes NAD+ reserves as we age³. This targeted drainage affects ovarian tissue specifically, potentially accelerating fertility decline. Your immune system inadvertently reduces the very molecule your eggs need to thrive.

Another study published in Nature Communications revealed the crucial role of NAD+ in egg cell division and quality⁴. The research team discovered that when NAD+ levels decrease in aging eggs, two specific problems occur:

The spindle (the cellular structure that helps separate chromosomes during cell division) becomes abnormally long
The egg loses its ability to complete a critical fast movement during division

Both issues affect the egg’s ability to divide properly – a process that must happen precisely for successful reproduction. During normal egg cell division, most cellular material needs to stay with the egg while only a small portion separates. When NAD+ levels are low, this precise division becomes compromised.

This high-impact research found that NAD+ levels naturally decrease in mouse eggs as they age. This decrease directly affects the egg cells’ mitochondria, reducing their function. Since eggs require significant energy to develop properly, this loss of energy production capability helps explain why egg quality tends to decline with age.

The study demonstrated that maintaining higher NAD+ levels helped preserve proper egg cell division and function. This suggests that finding ways to support NAD+ levels might help maintain egg quality as females age.

NMN Restores Oocyte Quality and Fertility

The success of reproduction hinges on egg cell health. These specialized cells require immense energy reserves to orchestrate fertilization, execute precise cell division, and support early embryo development. When cellular energy falls short, reproductive potential diminishes.

Scientific research published in Cell Reports revealed that NAD+ precursor NMN (nicotinamide mononucleotide) demonstrates remarkable potential in maintaining cellular energy production and supporting reproductive function⁵.

The researchers examined aging female mice, documenting telltale signs of reproductive decline in their egg cells. Mitochondrial efficiency had decreased significantly, resulting in reduced cellular energy production.

This energy deficit impaired proper egg development and embryo support. The aging eggs also showed increased chromosomal abnormalities—a direct threat to fertility.

NMN supplementation produced striking improvements across multiple markers of reproductive health. The treated eggs showed enhanced mitochondrial function and restored energy production.

Most significantly, egg quality and viability improved markedly, supporting superior embryo development despite advanced maternal age.

The benefits appear to flow through NAD+-dependent pathways, with particular emphasis on the SIRT2 enzyme’s role in egg quality enhancement. This research not only proves a fundamental truth that maintaining optimal NAD+ levels is a cornerstone of reproductive cellular health, but also represents a promising non-invasive treatment approach for age-related female infertility.

The findings suggest potential applications in both natural conception and IVF treatment, offering hope for improved fertility outcomes while reducing the financial and emotional burden often associated with fertility challenges.

NAD+ Supplementation Helps Treat Reproductive Diseases

A 2024 review published in Biochemistry and Biophysics Reports reveals the wide-ranging benefits of NAD+ supplementation for female reproductive health⁶. The researchers found that ovarian NAD+ levels decline dramatically with age, showing a 50-70% reduction in 8-month-old mice.

The study demonstrates that supplementation with NAD+ precursors effectively addresses age-related decline in oocyte quality. By improving mitochondrial function and reducing oxidative stress, NAD+ supplementation helps maintain proper chromosome structure and spindle assembly during cell division.

For women with PCOS, the research highlights how NAD+ precursor supplementation helps regulate insulin sensitivity and reduce chronic inflammation. This occurs through the AMPK-SIRT1 pathway, which enhances oocyte and embryo quality through anti-inflammatory and antioxidant effects.

The researchers also uncovered NAD+’s critical role in pregnancy outcomes. Their analysis revealed that NAD+ deficiency during pregnancy can lead to birth defects and pregnancy loss, while maintaining adequate NAD+ levels through supplementation supports normal embryonic development.

Most notably, the study found that long-term NAD+ precursor supplementation shows better results than short-term interventions. This insight suggests the importance of sustained supplementation strategies for optimal reproductive health outcomes.

NMN Supplementation Maintains Ovarian Health During Aging

A significant 2024 published in MedComm examined how NMN supplementation affects aging ovaries⁷. The researchers found that NMN supplementation in aging mice achieved several important results:

Restored NAD+ levels in aging ovarian tissue

Prevented ovarian atrophy (shrinkage)

Increased the quantity and quality of egg cells

Improved hormone production

Enhanced antioxidant activity

Reduced inflammation

Increased the number of viable ovarian follicles

The researchers used advanced microscopy to examine cellular changes, revealing that NMN treatment improved the health of key ovarian cells (granulosa cells) by enhancing their energy-producing structures (mitochondria).

While NMN treatment successfully improved several markers of ovarian health, it’s important to note that it did not restore fertility in very old mice, suggesting there may be a window of opportunity for intervention before age-related fertility decline becomes too advanced.

This research provides promising evidence that NMN supplementation could help maintain ovarian health during aging, potentially offering new approaches for fertility preservation in women. However, timing of intervention may be crucial for effectiveness.

Can NAD+ Supplementation Improve Your Sleep Quality?

Written by Jinfiniti Science on January 20, 2025. Posted in NAD+, NAD, NAD+ Precursors, Nicotinamide, Sleep. No Comments on Can NAD+ Supplementation Improve Your Sleep Quality?

Getting a good night’s sleep shouldn’t feel like chasing an impossible dream. Yet for many people, quality sleep remains frustratingly elusive, despite following all the standard advice about blue light, bedtime routines, and bedroom temperature.

The solution might lie not in your bedroom, but in your cells.

Among the many molecules involved in sleep regulation is NAD+ (Nicotinamide Adenine Dinucleotide), which plays an important role in your body’s circadian rhythms – the internal clock that helps regulate sleep and wake cycles. This molecule works alongside other important factors like hormones and neurotransmitters to influence sleep patterns.

Let’s explore what science tells us about the role of NAD+ in sleep quality and whether boosting NAD+ levels could help you get better rest.

Key Takeaways:

NAD+ plays a fundamental role in regulating your body’s circadian rhythms and sleep-wake cycles, with research showing its levels directly impact sleep quality and duration
Scientific studies have demonstrated that maintaining optimal NAD+ levels can improve sleep efficiency and may even reduce the amount of sleep needed to feel restored
Your body’s NAD+ levels naturally decline with age, but can be boosted through physical activity, diet, and targeted supplementation to support better sleep patterns

What is NAD+?

NAD+ is a coenzyme involved in hundreds of biological processes, including the regulation of circadian rhythms and mitochondrial function that directly influence sleep-wake cycles, making it a fundamental molecule for maintaining healthy sleep patterns and cellular repair during rest¹. Researchers are actively exploring NAD+’s potential benefits across multiple areas where declining levels impact aging including sleep quality, athletic performance, and skin health.

Does NAD+ Improve Sleep Quality? A Look at the Evidence

Wonder why some nights you sleep better than others? Beyond the usual suspects like late-night coffee or racing thoughts, your cellular NAD+ levels help regulate your sleep quality at the molecular level.

Here’s an overview of the latest research on how your body’s NAD+ status can shape your nightly rest.

Circadian Rhythm Regulation

Your body isn’t just randomly waking up and going to sleep. It runs on an exquisitely precise internal clock. This biological timekeeper is known as your circadian rhythm and tells your body when it’s time to be awake and when it’s time to start winding down.

Research in Molecular Cell has shown that NAD+ controls circadian reprogramming and decreases in total NAD levels are associated with circadian and sleep–wake disruptions². This drop directly impacts quality of sleep, often leaving you feeling unrested, even when following a normal sleep schedule.

Sleep-Wake Metabolism

Your brain doesn’t just power down when you sleep – it actually shifts into a different kind of energy mode. During deep sleep, your brain uses about half as much glucose as it does when you’re awake. This major metabolic shift involves NAD+, which helps convert nutrients into energy your cells can use.

During your waking hours, your brain accumulates some natural wear and tear from all its activity. When you sleep, NAD+ helps coordinate the complex chemistry that cleans up this cellular stress.

A recent study found that supplementation with NAD+ precursor nicotinamide riboside resulted in subjects requiring less sleep to get the same restorative benefits – about 17% less deep sleep, to be exact³. This would be equivalent to reducing human sleep from 8 to 6.6 hours.

Sleep Duration and Efficiency

Recent research suggests that NAD+ and its reduced form NADH play important roles in sleep regulation, particularly in people with chronic fatigue syndrome (ME/CFS). When ME/CFS patients were given a combination of NADH and CoQ10 daily, researchers observed several improvements in sleep-related measures⁴:

Sleep duration showed significant improvement at 4 weeks into treatment

Habitual sleep efficiency improved at 8 weeks

These improvements were observed within the treatment group, suggesting the supplements may help optimize sleep patterns

Apigenin and NAD+ Levels

Apigenin is a flavonoid found abundantly in parsley and chamomile and known for its ability to enhance sleep quality. Research has demonstrated that apigenin acts as an inhibitor of CD38, an enzyme that continuously breaks down NAD+ in the body⁵.

Through this protective mechanism of CD38 inhibition and NAD+ preservation, apigenin has been shown to improve multiple aspects of sleep, including reducing time to fall asleep and increasing the duration of deep, restorative sleep phases⁶.

Quality of Sleep in Parkinson’s Disease

Sleep disturbances are a hallmark of neurodegenerative diseases like Parkinson’s, where disrupted NAD+ metabolism plays a significant role. Research suggests that cellular energy deficits in these conditions correlate with declining NAD+ levels, which can further impact sleep quality.

One study examining niacin supplementation reported modest but meaningful improvements in sleep patterns – including a 10% reduction in nighttime awakenings⁷. While not dramatic, maintaining stable sleep patterns in progressive neurological conditions represents an important outcome.

Reduced Daytime Sleepiness

Research has shown that NMN (nicotinamide mononucleotide) reduces afternoon drowsiness in older adults by converting directly into NAD+ in your cells, helping maintain healthy sleep-wake patterns without disrupting nighttime rest⁸.

This suggests that taking NMN strategically in the afternoon can help reset your daily rhythm—eliminating post-lunch fatigue while preparing your body for deeper, more restorative sleep at night.

How to Improve NAD+ Levels for Healthier Sleep

NAD+ levels decline dramatically as you age, dropping by about 50% between your 20s and 80s. This reduction directly impacts your sleep cycles and cellular repair processes.

When NAD+ levels fall, you spend less time in deep sleep phases. These stages are where your body conducts essential maintenance: repairing cells, restoring energy, and regulating vital functions. Without sufficient deep sleep, fatigue and reduced resilience become daily challenges.

The great news? Scientific research confirms that optimizing your NAD+ levels can provide relief from common sleep issues. When your NAD+ levels are balanced, your body is better equipped to enter the deep, restorative sleep phases essential for repair, recovery, and overall rejuvenation.

Three primary strategies can help maintain and boost your NAD+ levels:

Physical Activity: Regular exercise naturally stimulates NAD+ production in your cells. Research shows that consistent physical activity helps maintain NAD+ at levels typically seen in younger adults, supporting both sleep quality and cellular energy production⁹.

Diet and Nutrition: Several foods naturally support NAD+ levels through precursor molecules. Wild-caught fish, mushrooms, and leafy greens provide building blocks for NAD+ synthesis. However, dietary sources alone rarely provide sufficient NAD+ precursors to counter age-related decline.

Targeted Supplementation: Direct supplementation with NAD+ precursors provides the most efficient way to boost cellular NAD+ levels. Modern supplement formulations can deliver precise dosages of compounds that your body converts directly into NAD+.

Vitality ↑® NAD+ Booster offers a comprehensive approach to NAD+ optimization. Our clinically-validated NAD powder formulation combines precursors NMN and niacinamide with synergistic ingredients D-ribose and creatine monohydrate. This precise combination supports both NAD+ production and cellular energy systems.

With consistent NAD+ supplementation at the right dosage, you can increase NAD levels and create a positive cycle where better sleep supports cellular repair, and optimized cellular function promotes higher quality rest.

Frequently Asked Questions

Can NAD+ Help for Insomnia?

NAD+ directly influences your sleep-wake cycles at the molecular level, making it particularly relevant for sleep quality and insomnia. The coenzyme regulates your internal clock while powering the cellular processes that enable deep, restorative sleep.

Science shows that optimal NAD+ levels support sleep cycle regulation, cellular energy production during rest, nighttime repair processes, and stress response systems. These benefits become more important with age, as NAD+ levels naturally decline. Testing and maintaining proper NAD+ levels through targeted supplementation can help restore natural sleep patterns, especially for those experiencing age-related insomnia.

Does NAD Make You Sleepy?

NAD+ doesn’t induce drowsiness. Instead, it optimizes your body’s natural energy cycles. NAD+ actually does the opposite of making you sleepy – it can help improve sleep quality and reduce fatigue while potentially decreasing overall sleep time.

Should NAD+ Be Taken in the Morning or at Night?

Most people benefit from taking NAD+ supplements in the morning to support daytime energy production. Some research suggests afternoon supplementation can help reduce evening fatigue while supporting nighttime sleep quality. The key is consistency—regular supplementation maintains steady NAD+ levels for optimal results.

How Long Does it Take NAD+ to Start Working?

While individual responses vary, many people notice improvements in energy levels within the first few weeks of consistent NAD+ supplementation. The full spectrum of benefits, including improvements in poor sleep quality and cellular repair—typically develop over continued use as your body’s NAD+ levels stabilize at optimal ranges.

20 Foods That Boost NAD Levels

Written by Jinfiniti Science on January 16, 2025. Posted in NAD+, NAD, NAD+ Precursors. No Comments on 20 Foods That Boost NAD Levels

Most people obsess over macros and vitamins. But at the molecular level, something more fundamental is at work: NAD+ (Nicotinamide Adenine Dinucleotide), the coenzyme that powers your cells’ ability to generate energy, repair DNA, and maintain peak function.

Specific foods can influence your NAD+ levels, directly impacting your cellular performance, energy, and even how you age.

In this guide, we’ll explore the foods scientifically shown to support healthy NAD+ levels, giving you practical tools to optimize your cellular health through strategic nutrition.

Key Takeaways:

NAD+ naturally declines with age, dropping up to 50% by age 50, but specific foods rich in vitamin B3 compounds and tryptophan can support your body’s NAD+ production.
Three primary nutritional precursors influence NAD+ levels: B3 compounds (niacin and niacinamide), tryptophan, and direct precursors like NMN and NR.
Wild-caught fish, lean meats, seeds, and whole grains top the list of NAD+ supporting foods, offering essential precursors for cellular energy production.
While diet provides a foundation, factors like aging, chronic stress, and modern lifestyle challenges may create demands that exceed what food alone can provide.

Nutrients That Support NAD+ Production

Your cellular health depends on more than just basic vitamins and minerals. Deep within your cells, specific nutrients act as molecular building blocks and catalysts for NAD+ production—the backbone of cellular energy and longevity.

Research has identified three primary nutrient precursors that influence your body’s NAD+ levels:

B3 Compounds: The most direct nutritional route to NAD+ production comes through vitamin B3 (niacin and niacinamide). A 2020 study in Cell Metabolism demonstrated that niacin increased blood NAD+ levels up to 8-fold¹, offering potential therapeutic benefits for conditions linked to NAD+ deficiency.
Tryptophan: This essential amino acid provides an alternative route to NAD+ synthesis. Research published in the International Journal of Tryptophan Research mapped how tryptophan converts to NAD+ through the kynurenine pathway², revealing an important backup system for maintaining cellular energy.
Direct Precursors: NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) represent the newest frontier in NAD+ optimization. These compounds bypass several metabolic steps for a more efficient path to NAD+ production, although they are only present in small amounts in food.

Understanding these nutrients is just the beginning. The real power lies in knowing which foods activate them most effectively.

Top 20 NAD Boosting Foods

Your next meal could change your cellular health for the better. Foods high in NAD+ boosting precursors like the various forms of vitamin B3 provide a foundation for optimal cellular function. When combined with a healthy lifestyle, these scientifically validated foods supply the key building blocks your body needs to increase NAD levels naturally.

Wild-Caught Fish (Salmon, Tuna, Sardines, Anchovies) – These nutrient-dense fish not only support cellular metabolism as an excellent source of niacin but also offer additional health benefits like omega-3 fatty acids.
Meat (Chicken, Turkey, Beef, Pork) – These protein sources contain significant amounts of vitamin B3 and tryptophan, two essential precursors your body uses to produce NAD+.

Is Food Enough for Optimal NAD+ Levels?

NAD+ levels usually start dropping in your 20s. After age 40, NAD+ levels begin declining sharply and, by age 50, they’ve typically fallen to half their youthful levels³. Diet alone often can’t offset this natural decrease.

Modern life creates additional challenges for maintaining NAD+ levels. Chronic stress⁴, insufficient sleep, alcohol consumption⁵, excessive sun exposure, and a sedentary lifestyle can all accelerate NAD+ depletion.

Not to mention, even pristine nutrition faces biological limitations:

Absorption Barriers: Your body’s ability to extract and convert NAD+ precursors from food becomes less efficient with age
Metabolic Demands: Modern stressors deplete NAD+ faster than traditional diets evolved to handle
Precursor Availability: Many foods contain NAD+ building blocks, but not in the concentrated amounts needed to overcome age-related decline

Supplementation may be worth considering when facing significant NAD+ depletion factors like advanced age, chronic stress, poor sleep, or intense athletic training. These situations create demands that exceed what diet alone can provide, making supplementation a valuable reinforcement for true cellular resilience.

How to Optimize NAD+ Beyond Diet

While nutrition provides essential building blocks, your cells often need additional support to maintain optimal NAD+ levels—especially in the face of aging and environmental stressors.

Direct NAD+ precursors like NMN and NR deliver concentrated, bioavailable forms of these vital molecules straight to your cells. Unlike dietary sources, these compounds bypass multiple conversion steps, providing a more efficient path to optimal NAD+ levels.

This matters because signs of NAD+ depletion, like fatigue, brain fog, or slower recovery, often signal a deeper cellular energy crisis that diet alone can’t resolve. Your cells need targeted support to maintain peak performance.

Therefore, while a nutrient-rich diet forms the cornerstone of health, strategic supplementation with NAD+ precursors⁶ provides the extra support your cells need to thrive in today’s demanding world.

Our flagship Vitality ↑® NAD+ Booster combines premium NMN with synergistic compounds like Creatine Monohydrate, D-Ribose, and Niacinamide. This patent-pending formula maximizes NAD+ production through multiple pathways, supporting optimal cellular function and energy production.

NMN vs NMNH Differences, Benefits & Risks

Written by Jinfiniti Science on January 14, 2025. Posted in NAD+, NAD, NAD+ Precursors, NMN, Premature Aging. No Comments on NMN vs NMNH Differences, Benefits & Risks

NAD+ precursors aren’t created equal. While NMN has established itself as a cornerstone of NAD+ supplementation, its reduced form NMNH has emerged as a potential challenger—promising faster absorption and higher NAD+ increases in preliminary research.

These two molecules take distinct biochemical paths to boost your NAD+ levels. Understanding their differences matters not just for scientific accuracy, but for making informed decisions about your health optimization strategy.

Key Takeaways:

NMN offers a well-researched path to NAD+ enhancement, supported by extensive human trials and a documented safety profile.
NMNH may provide faster NAD+ increases by bypassing certain enzymatic steps, though human studies are still pending.
Both compounds aim to restore declining NAD+ levels, but they differ in stability, absorption mechanisms, and current scientific validation.
Molecular structure sets them apart—NMNH carries an extra hydrogen molecule that alters its biological processing.

What’s the Difference Between NMN and NMNH?

An image of a matured woman taking supplement

NMN and NMNH take different paths to reach the same destination: higher NAD+ levels in your body. Let’s look at what sets these two compounds apart and why these differences matter for your health.

Molecular Structure

NMN (nicotinamide mononucleotide) is a direct precursor to NAD+. It consists of a nicotinamide moiety attached to ribose and a phosphate group, forming a nucleotide that the body can use to synthesize NAD+¹. Meanwhile, NMNH (dihydronicotinamide mononucleotide) is the reduced form of NMN, carrying an extra hydrogen on the nicotinamide ring.²

This additional hydrogen changes certain properties, which can lead to more robust or faster NAD+ increases in some studies. However, contrary to earlier assumptions that NMNH might be “more stable” in the digestive tract, research indicates NMNH is actually less stable than NMN at neutral pH.³

Metabolic Pathways

NMN can become NAD+ through two major routes. First, the salvage pathway, where nicotinamide (NAM) is converted into NMN by NAMPT and then NMN is turned into NAD+ by NMNAT⁴. Second, the de novo pathway generating NAD+ from tryptophan or niacin produces NaMN and other intermediates rather than directly synthesizing NMN from scratch⁵. Most NMN used in cells arises from recycling NAM, making the salvage pathway the predominant and more energy-efficient route.

NMNH appears to follow a simpler, faster route. It bypasses enzymes such as NAMPT and NRK, continuing instead through NMNAT-related steps that can directly lead to NAD+ and NADH. This streamlined path may underlie reports of faster or higher NAD+ increases, as fewer conversion steps are required to boost intracellular NAD+ and NADH levels.⁶

Absorption and Bioavailability

One of the key factors in assessing the effectiveness of a supplement is its absorption and bioavailability. NMN has been shown to be absorbed through the gut⁷ and into the bloodstream, but its bioavailability can be influenced by various factors such as gut health, digestive enzymes, and the presence of other nutrients. While some research suggests that NMN may be degraded in the gut before absorption, recent studies have demonstrated that orally administered NMN can lead to increased NAD+ levels in various tissues, indicating successful absorption and utilization⁸.

Meanwhile, NMNH has demonstrated a higher potency in elevating NAD⁺ levels in vitro and in animal models, potentially through bypassing certain rate-limiting steps that NMN must undergo⁹. However, there are currently no published human clinical trials investigating NMNH. Since the enhanced effects observed in preclinical studies have not yet been confirmed in humans, it remains speculative whether NMNH will provide more rapid or extensive NAD+ boosts in real-world use. Until more human data become available, NMNH’s practical advantages over NMN should be interpreted with caution.

Research Status

While NMN has been well-researched over the past few years, NMNH is still in the early stages of study. We know NMN boosts NAD+ levels, supports mitochondrial function, and benefits overall health, but there’s not enough research on NMNH yet to fully grasp its potential.

NMN has been widely studied and has shown promising results in various areas of health, including anti-aging, metabolism, cardiovascular health, and cognitive function. Studies on animals and humans alike have demonstrated NMN’s ability to increase NAD+ levels and support mitochondrial health.¹⁰

Benefits of NMN and NMNH Compared

An image of a strong matured woman benefiting from NMN and NMNH

NMN and NAD+ have become household names in the world of cellular health and longevity. While these molecules have revolutionized how we approach energy production and aging at the cellular level, breakthrough research on NMNH is pushing the boundaries even further.

As we’ve seen, NMN and its reduced form, NMNH, are both NAD+ precursors with potential health benefits. However, early research points to NMNH being a more potent enhancer of NAD+ levels compared to NMN.

NMN Benefits

NAD+ Restoration: Clinical studies show NMN can increase NAD+ levels, which decline with age, by about 40% within 30 days¹¹. NMN’s ability to boost NAD+ has been shown to offset age-related diseases and improve vascular function, cognitive performance, and oocyte quality in aged models.¹²

Gut Health: Long-term NMN treatment can modulate gut microbiota, increasing beneficial bacteria and reducing harmful ones, which may enhance intestinal barrier function¹³.

Heart Health: NMN supplementation has been shown to decrease oxidative stress in heart tissue, lower inflammation in the cardiovascular system, and protect against DNA damage in heart cells¹⁴.

Anti-Aging Effects: NMN supplementation has been linked to anti-aging effects¹⁵, including improved vascular function and reduced oxidative stress, through mechanisms involving sirtuin activation.

NMNH Benefits

Potentially Superior NAD+ Enhancement: NMNH may increase NAD+ levels¹⁶ more effectively and rapidly than NMN or NR, through a different metabolic pathway.

Metabolic Effects: NMNH suppresses glycolysis and the TCA cycle, and induces cell cycle arrest, which may have implications for cell growth regulation¹⁷.

Tissue Protection: NMNH has shown potential in reducing damage and accelerating repair in renal cells under stress conditions¹⁸.

While both NMN and NMNH are beneficial as NAD+ precursors, early NMNH research suggests it may be more efficient in raising NAD+ levels and has unique metabolic effects that may offer additional therapeutic benefits. NMN, however, has broader documented benefits in age-related health improvements and gut health. Further research is needed to fully understand the distinct and overlapping benefits of these compounds.

Potential Risks of NMNH and NMN

An image of a matured woman with flushing or warmth in the skin

NMN has been studied extensively in both animal and human trials, and so far, it has shown a strong safety profile¹⁹. Most users tolerate NMN well, even at higher doses²⁰. Some people, however, report mild side effects that are generally rare and short-lived, such as:

Temporary flushing or warmth in the skin
Skin problems like itching and sweating
Mild to moderate headaches
Dizziness
Fatigue and lethargy
Sleep disturbances
Mild gastrointestinal issues

NMNH is a newer compound, and research into its safety is still in the early stages. While preliminary studies haven’t flagged adverse effects, the lack of data means the potential side effects remain uncertain. The structural differences between NMN and NMNH could lead to unique interactions in the body, but until more human trials are conducted, we don’t have enough information to draw firm conclusions.

NMN vs NMNH: Which is Right For You?

An image of a matured men and women exercising

NMN stands as the gold standard for NAD+ enhancement. Its extensive research background and established safety profile make it the clear choice for those seeking evidence-based supplementation.

NMNH represents the cutting edge—promising but unproven. While preliminary data suggest potential advantages in NAD+ biosynthesis, the limited research makes it better suited for those comfortable with scientific uncertainty.

Most healthcare professionals align with the data: NMN’s documented safety and efficacy outweigh NMNH’s theoretical benefits.

For optimal results, consider our clinically-validated NAD powder supplement Vitality NAD+ Booster—a patent-pending formula combining NMN with synergistic compounds that maximize cellular energy production.

If you prefer simplicity, Pure NMN offers >99.5% purity at a more accessible price point. Both options deliver measurable NAD+ increases, verified through our Intracellular NAD® Test.

What’s the Difference Between NAD and NAC?

Written by Jinfiniti Science on January 10, 2025. Posted in NAD+, NAD, NAD+ Precursors, Supplements. No Comments on What’s the Difference Between NAD and NAC?

NAD and NAC are two of the most frequently confused supplements in the anti-aging and health optimization space. While their names might look similar on a bottle, these molecules serve fundamentally different roles in your cellular machinery.

The confusion stems from more than just their similar-looking acronyms. Both molecules support cellular health, both decline with age, and both have drawn widespread interest in the longevity research community. But their mechanisms of action, supplementation strategies, and optimal testing methods differ significantly.

This guide will break down exactly what sets NAD and NAC apart, explore their unique roles in cellular function, and explain why tracking your NAD levels through precise testing provides crucial insights that simply aren’t available for NAC. We’ll examine how each compound supports your body’s cellular processes and help you understand which one—or whether both—might be right for your health optimization goals.

Key Takeaways

NAD and NAC serve fundamentally different roles in your cells. NAD powers energy production in every cell, while NAC supports your body’s antioxidant defense systems.
Testing makes the difference in optimizing your NAD levels. While both molecules support cellular health, only NAD levels can be precisely measured through intracellular testing to guide supplementation.
Strategic supplementation may include both molecules. NAD precursors typically provide more direct benefits for energy and longevity, while NAC offers complementary antioxidant support for overall cellular protection.

What is NAD? The Cellular Energy Master

Nicotinamide adenine dinucleotide, or NAD for short, exists in every cell of your body, orchestrating hundreds of biological processes essential for life itself¹. The molecule is a fundamental coenzyme that transforms the food you eat into cellular energy.

NAD exists in two main forms in your cells: NAD+ (the oxidized form) and NADH (the reduced form). This dynamic pair works together in a continuous cycle, with NAD+ accepting electrons to become NADH, and NADH donating electrons to convert back to NAD+. This electron transfer process lies at the heart of cellular energy production.

In the mitochondria, NADH transfers its electrons to the electron transport chain, converting back to NAD+ in the process. This electron handoff drives the production of ATP—your cells’ primary energy source. The constant cycling between NAD+ and NADH maintains the delicate balance needed for optimal cellular function².

NAD+ to NADH conversion cycle

But NAD+ does more than just energy production. It serves as a critical cofactor for:

Sirtuins, the proteins that regulate cellular aging and DNA repair³
PARPs, which help maintain genome stability⁴
CD38, an enzyme involved in immune function and calcium signaling⁵

The not-so-great aspect is that intracellular NAD+ levels naturally decline with age. By the time you reach 60, you typically have less than half the NAD+ you had at age 20. This decline isn’t just a number—it correlates directly with many hallmarks of aging, from reduced energy to impaired cellular repair.

Your cells can create NAD+ through several pathways, using precursors like:

NMN (nicotinamide mononucleotide)
NR (nicotinamide riboside)
Vitamin B3 forms niacin and niacinamide

However, not all precursors are equally effective. Measuring your actual intracellular levels through NAD testing remains the only reliable way to know if your supplementation strategy is working. Blood tests can’t tell you what’s happening inside your cells, where NAD+ actually performs its critical functions.

What is NAC? The Antioxidant Precursor

NAC (N-acetyl cysteine) is a unique amino acid derivative that serves as a direct precursor to glutathione—your body’s primary internal antioxidant defense system. Unlike NAD, which handles energy production, NAC’s primary role centers on cellular protection and detoxification⁶.

Inside your cells, NAC converts to cysteine, the rate-limiting building block for glutathione production. Without adequate cysteine, your cells can’t maintain optimal glutathione levels. This matters because glutathione:

Neutralizes harmful free radicals⁷
Supports your body’s detoxification processes⁸
Helps maintain cellular redox balance⁹
Protects against oxidative stress¹⁰

Beyond its role in glutathione production, NAC exhibits direct antioxidant properties. It can break down mucus proteins, which explains its long history of clinical use in respiratory conditions¹¹. This dual action—both as a direct antioxidant and as a glutathione precursor—makes NAC particularly valuable for cellular defense.

Your body’s need for NAC increases during periods of:

Environmental toxin exposure
Intense physical exercise
Respiratory challenges
Metabolic stress
Inflammation

While NAC naturally occurs in high-protein foods, the supplemental form offers more direct benefits because it bypasses digestive breakdown. However, timing matters—NAC is best absorbed on an empty stomach, away from protein-rich meals that might compete for absorption.

Unlike NAD, which requires specialized testing to measure intracellular levels, glutathione status can be assessed through standard blood tests. However, these measurements don’t always reflect tissue levels, making symptoms and overall health markers important guides for supplementation.

NAD vs NAC Key Differences Explained

At first glance, NAD and NAC might seem similar since both support cellular health and both become more important as we age. But their molecular roles and impacts on your body couldn’t be more distinct.

Structural Differences

NAD exists as a complex coenzyme, switching between its oxidized and reduced forms during energy production. NAC, in contrast, is a modified amino acid, serving as a precursor molecule that your body converts into other compounds.

Primary Functions

NAD orchestrates energy production in your mitochondria, enabling the conversion of nutrients into ATP¹². Every cell in your body depends on this process. Think of NAD as your cellular energy’s master conductor.

NAC takes a different path. It serves as raw material for glutathione production. While NAD powers your cellular engines, NAC helps maintain your cellular defense systems.

Location and Action

Inside your cells, NAD concentrates in specific areas:

Mitochondria for energy production
Nucleus for DNA repair
Cytoplasm for metabolic reactions

NAC, once absorbed, rapidly converts to cysteine and disperses throughout your tissues, with particular affinity for the liver—your body’s primary detoxification center.

Testing and Optimization

Measuring NAD requires specialized intracellular testing methods. Standard blood tests can’t accurately reflect your cellular NAD status. That’s why the Intracellular NAD® Test provides crucial insights for optimization.

Glutathione levels, influenced by NAC supplementation, can be measured through conventional blood tests. However, these measurements don’t always correlate perfectly with tissue levels or functional status.

Supplementation

NAD levels respond to precursor supplementation with compounds like NMN and NR. Your cells can use these building blocks to manufacture new NAD molecules—a process that becomes more critical as you age.

NAC supplementation works differently. Your body uses it both directly as an antioxidant and as raw material for glutathione production. This dual-action approach makes NAC particularly valuable during periods of increased oxidative stress.

Aspect	NAD	NAC
Structure	Complex coenzyme that switches between oxidized and reduced forms	Modified amino acid that serves as a precursor molecule
Primary Function	Orchestrates cellular energy production by converting nutrients into ATP	Serves as raw material for glutathione production and supports cellular defense systems
Cellular Location	Concentrates in mitochondria, nucleus, and cytoplasm	Converts to cysteine and disperses throughout tissues, particularly in the liver
Testing Methods	Requires specialized intracellular testing; standard blood tests insufficient	Can be measured through conventional blood tests (via glutathione levels)
Supplementation	Responds to precursor supplements like NMN and NR	Used directly as antioxidant and as raw material for glutathione production

NAC vs NAD Supplements for Anti-Aging

Both NAC and NAD precursors have demonstrated promising benefits for age-related health and longevity. The choice between the two depends on individual health goals and specific healthy aging concerns. Some researchers are even exploring combinations of antioxidants and NAD precursors for synergistic effects¹³.

Given the complexity of aging, a multi-faceted approach that includes both antioxidant support (like NAC) and metabolic enhancement (via NAD precursors) might be most beneficial. However, the extensive longevity research behind NAD+¹⁴ and its fundamental role in cellular energy production makes NAD precursors the more compelling choice if you need to prioritize one over the other.

For those focused on optimizing their NAD+ levels, Vitality ↑® NAD+ Booster offers a comprehensive solution. This patent-pending NAD supplement powder formula combines NMN with synergistic ingredients like D-ribose, niacinamide, and creatine monohydrate to support optimal NAD+ levels, boost energy production, and enhance sleep quality. Pair it with our Intracellular NAD® Test to measure your results and optimize your dosage for maximum benefits.

Can NAD and NAC Be Taken Together?

NAC and NAD complement each other in supporting cellular resilience. NAD supplements drive energy production in your mitochondria, while NAC strengthens your antioxidant defenses. This combination becomes particularly powerful as energy production naturally generates free radicals—NAC helps neutralize these byproducts while NAD maintains optimal energy flow.

Timing Matters

NAD precursors absorb best with food, while NAC shows optimal absorption on an empty stomach. Space them several hours apart—NAD with breakfast for sustained energy, NAC between meals or before bed.

When to Consider Both

The NAD/NAC combination proves most valuable during:

Intense physical or mental demands
Environmental stress exposure
Implementation of longevity protocols
Age-related cellular decline

Are NAD and NAC Safe to Use?

Both NAD and NAC have strong safety profiles backed by decades of clinical use. However, their distinct mechanisms mean different considerations for each.

NAD precursor supplements like NR show remarkable tolerance in research studies¹⁵. Most people report no side effects beyond occasional mild flushing—similar to what you might experience from vitamin B3.

NAC’s safety record spans over 50 years of clinical use¹⁶, first as a medical intervention and now as a supplement. Its most common side effect is a distinctive sulfur smell that has no impact on its benefits. Some people notice mild digestive effects when starting NAC, which typically resolve by taking it with food.

Key precaution: Always consult healthcare providers if you’re on medications, as NAC in particular can interact with certain drugs due to its effects on liver function.

Frequently Asked Questions

Does NAC Boost NAD+ Levels?

NAC does not directly support NAD+ levels, but it may indirectly contribute to maintaining or enhancing NAD+ levels through several mechanisms. One study demonstrates that NAC can inhibit NADPH oxidase activation in various tissues¹⁷. This effect may indirectly support NAD+ levels since NADPH oxidase produces reactive oxygen species (ROS) that can deplete NAD+.

Are NAC and NAD the Same?

As we have seen above, these are entirely different molecules. NAC is an amino acid derivative that supports antioxidant production, while NAD is a coenzyme essential for cellular energy production. Despite their similar-sounding names, they serve distinct biological functions.

What’s the Difference Between NAC and NMN?

NMN supplements are direct precursors to NAD+, helping your cells produce more of this vital coenzyme. NAC, on the other hand, has no direct relationship to NAD+ production—it supports glutathione synthesis and antioxidant defense.

Does Taking NAD+ or NAC Help With Sleep?

NAD+ levels influence your circadian rhythm and sleep-wake cycles¹⁸. Many users report improved sleep quality with NAD+ precursor supplementation. NAC’s effects on sleep are less direct, though some find its antioxidant properties support overall sleep quality by reducing oxidative stress.

How Long Does It Take to See Results?

Individual responses vary, but most people notice initial effects from NAD+ supplementation within 2-4 weeks, particularly in energy levels and mental clarity. Regular testing can track your progress objectively. NAC’s effects on oxidative stress markers typically become apparent within similar timeframes.

6 Benefits of NAD for Athletic Performance and Recovery

Written by Jinfiniti Science on January 9, 2025. Posted in NAD+, Exercise, NAD+ Precursors. No Comments on 6 Benefits of NAD for Athletic Performance and Recovery

Your athletic potential lives and dies at the molecular level. While others focus on surface-level metrics, elite performers understand a deeper truth: cellular energy production determines who breaks records and who hits the wall.

Enter NAD+: the molecular backbone of athletic excellence.

This coenzyme drives the fundamental chemical reactions that transform nutrients into ATP, your body’s high-octane cellular fuel. NAD+ supercharges your mitochondria, the microscopic powerhouses that energize every sprint, lift, and endurance push.

The science is clear: when NAD+ levels drop, athletic performance follows. Your muscles can’t fire at full strength. Recovery slows to a crawl. That extra gear you used to have? It vanishes.

The athletes who dominate their sports aren’t just training harder—they’re optimizing their cellular machinery. They’re ensuring their NAD+ levels stay primed for peak performance.

In this article, we’ll discuss…

6 benefits of NAD+ that can help you level up your athletic performance, recover faster, and make every workout count.

How NAD+ supports performance longevity and training consistency, so you can stay at the top of your game for years to come.

Simple ways to boost your NAD+ levels, giving you the edge for better energy, endurance, and recovery.

What is NAD?

NAD+ (nicotinamide adenine dinucleotide) is an important player in your body’s energy and metabolism game, especially if you’re an athlete. NAD is the engine behind converting carbs, fats, and proteins into ATP,¹ your body’s main energy fuel. Without enough NAD+, it’s harder to sustain energy during those long, intense training sessions.

It also helps repair cells and combat oxidative stress²—something your body deals with after tough workouts. The result is faster recovery, less muscle fatigue, and the ability to train harder and more often.

Benefits of NAD for Athletic Performance

If you’re an athlete looking to boost your performance and recovery, supporting healthy NAD+ levels can make all the difference. It’s like giving your body the tools it needs to hit new personal bests, day after day.

Here are the six top benefits of NAD to help you boost your athletic performance.

Energy Production and Endurance

During intense training and physical activity, your body’s energy needs multiply exponentially. NAD+ stands as the molecular gatekeeper between mediocre and exceptional performance.

In your mitochondria³, NAD+ drives the chemical cascade that transforms nutrients into ATP. More NAD+ means more power output, sustained longer.

But athletes face a biological paradox: The harder you train, the faster your NAD+ reserves deplete. Each explosive movement, each endurance milestone burns through your molecular energy currency.

The data reveals that athletes with optimal NAD+ levels have reduced fatigue⁴ and are able to push harder, last longer, and bounce back faster. Those with depleted reserves hit their limits sooner—watching their potential slip away.

Muscle Function and Fatigue Reduction

For peak performance, athletes need strong muscles and the stamina to fight fatigue. In studies involving muscular dystrophy models, NAD+ supplementation has been shown to improve muscle function, protect against muscle damage, and enhance running capacity⁵. NAD+ also helps mitigate muscle fatigue by supporting efficient energy production⁶.

Post-Workout Recovery and Muscle Repair

During the post-workout recovery phase, which typically spans seven days, skeletal muscle undergoes extensive remodeling through multiple NAD+-dependent pathways. The autophagolysosomal system relies on proper NAD+ function to degrade damaged components and provide building blocks for new tissue, while regenerative processes including satellite cell proliferation and immune cell activity work in concert to repair and strengthen muscle tissue⁷.

Research on Nmnat1, a nuclear NAD+ biosynthesizing enzyme, has revealed redundant pathways for maintaining NAD+ levels in skeletal muscle, highlighting the body’s robust mechanisms for preserving this essential molecule during recovery⁸.

Metabolic Efficiency

Athletes with efficient metabolism demonstrate better use of energy substrates during intense muscle activity⁹. They require high levels of NAD+ to fuel metabolic reactions and maintain optimal energy production during intense physical activity¹⁰.

NAD+ supports metabolic reactions that regulate the cell cycle and maintain energy balance¹¹. This helps athletes sustain their high energy demands during training and competition.

Mental Focus and Cognitive Function

NAD+ is crucial for maintaining mental focus and cognitive function, especially for athletes who rely on sharp concentration and quick thinking during training and competition.

The coenzyme helps maintain healthy cognitive function by optimizing the adjustment of cerebral blood flow to neuronal activity¹². This process, known as neurovascular coupling, is crucial for peak mental performance during athletic activities. NAD+ supplementation also shows protective effects on mitochondrial function and reduces oxidative stress in cerebrovascular cells. This improvement in cellular energy production can enhance mental clarity and focus during athletic performance.

Performance Longevity and Training Consistency

NAD+ levels decline with age, leading to lower energy production, reduced mitochondrial function, and slower recovery. Supplementing with NAD+ or boosting its levels can counteract these declines and help you to continue performing at your best.

With its support for ATP production in the mitochondria, NAD+ provides you with the energy needed to power through intense workouts and maintain training consistency.

NAD+ also activates sirtuins—proteins that regulate cellular stress and inflammation—improving recovery times and reducing the risk of injury. In short, NAD+ helps you extend your training sessions and excel in your sport, even as you get older.

How to Boost NAD Levels for Exercise Performance

Along with your regular workouts, focus on maintaining a nutrient-rich diet with foods high in vitamin B3 (niacin or niacinamide), like lean meats, fish, nuts, and green vegetables, to naturally support NAD+ production. Intermittent fasting is another strategy that can elevate NAD+ levels by activating metabolic pathways that enhance its production.

Supplementing with NAD+ precursors like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) can further amplify your results. NR quickly boosts NAD+ levels, improving muscle function and endurance, while NMN supports mitochondrial health, reduces fatigue, and enhances overall performance.

Elite athletes are discovering the performance advantages of NAD+ booster supplements. American track star Celera Barnes, who has clocked an impressive 10.82 seconds in the 100-meter sprint, relies on Vitality ↑® NAD+ Booster as part of her training regimen. Our advanced formula combines a clinically validated blend of powerful NAD+ precursors NMN and nicotinamide, as well as Creatine Monohydrate and D-Ribose, ingredients that work synergistically to efficiently boost NAD+ levels.
