9 Natural Senolytic Supplements You Need to Know

Written by Jinfiniti Science on . 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

Image of Quercetin

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)

Image of green tea which contains 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

Image of long pepper which contains 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

Image of turmeric root containing 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

Image of chamomile flowers containing 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

Image of grapes containing 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.

Can NAD+ Supplementation Improve Your Sleep Quality?

Written by Jinfiniti Science on . 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

A woman in a sleep mask

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

does nad help with 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

does nad help with sleep

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 . 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

An image of a

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

Is Food Enough for Optimal NAD+ Levels?

59 1

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

60 1

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 . 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.

Visual representation of omparison of two supplements: NAD and NAC

What’s the Difference Between NAD and NAC?

Written by Jinfiniti Science on . 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.

An image of NAD and NADH compounds

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.

NAD level decline visualization infographic

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

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.

AspectNADNAC
StructureComplex coenzyme that switches between oxidized and reduced formsModified amino acid that serves as a precursor molecule
Primary FunctionOrchestrates cellular energy production by converting nutrients into ATPServes as raw material for glutathione production and supports cellular defense systems
Cellular LocationConcentrates in mitochondria, nucleus, and cytoplasmConverts to cysteine and disperses throughout tissues, particularly in the liver
Testing MethodsRequires specialized intracellular testing; standard blood tests insufficientCan be measured through conventional blood tests (via glutathione levels)
SupplementationResponds to precursor supplements like NMN and NRUsed 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.

Vitality NAD+ Booster promotional image

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.

The Regenerative Benefits of NAD+ for Aging Skin

Written by Jinfiniti Science on . Posted in NAD+, NAD, NAD+ Precursors, Skin Health. No Comments on The Regenerative Benefits of NAD+ for Aging Skin

What if the secret to younger, more radiant skin lies not in a bottle of cream but within your cells? 

NAD+ (Nicotinamide Adenine Dinucleotide) is emerging as a game-changer in the world of anti-aging, hailed by dermatologists and longevity experts alike. This powerful molecule works behind the scenes, fueling your body’s ability to repair DNA, produce energy, and combat the visible signs of aging. 

Yet, as we age, NAD+ levels naturally plummet, leaving skin dull, dehydrated, and prone to wrinkles. 

The good news? Cutting-edge research suggests that replenishing NAD+ may not just slow the clock but turn back its hands, rejuvenating your skin from within.

Intrigued? Let’s dive into the science and discover how NAD+ could redefine your skincare routine.

In this article, we’ll discuss…

  • The science behind NAD+ and its crucial role in slowing the aging process of your skin.
  • The top benefits of NAD+ for radiant skin, including its ability to support cellular repair, boost hydration, and enhance overall skin vitality.
  • The pros and cons of using topical NAD+ skincare products.

NAD+ and Skin Aging

An image of a matured woman depicting aging

Think of NAD+ as the fuel behind your skin’s natural glow and resilience. This vital coenzyme powers cellular repair and energy production, but with the decline of NAD+ levels with age, your skin begins to show signs of wear and tear.One of the first signs is a slowdown in collagen production. Collagen is the protein responsible for keeping your skin firm and elastic.1 When NAD+ levels decline, collagen synthesis weakens,2 leading to sagging skin, fine lines, and wrinkles—the hallmarks of aging.

But the effects go beyond structure. NAD+ is crucial for activating DNA repair mechanisms in your skin cells. Sun exposure and UV damage can accelerate aging and increase the risk of skin cancers, but with adequate NAD+, your cells can combat these effects. Unfortunately, when NAD+ levels are low, your skin’s ability to repair itself diminishes, leaving it more vulnerable to environmental damage.

NAD+ also powers your skin’s mitochondria3—the energy generators of cells. Mitochondria produce ATP, the energy necessary for regeneration and repair. Declining NAD+ levels mean less energy for skin cells to renew themselves, leading to a dull, tired complexion and slower recovery.

Key Takeaway: NAD+ helps maintain skin health by powering collagen production, DNA repair, and cellular energy, but its decline with age leads to visible signs of aging.

NAD+ Benefits for Skin Health

An image of a matured woman with a healthy skin

When it comes to maintaining radiant, youthful skin, NAD+ is nothing short of a powerhouse. This essential coenzyme fuels critical processes like cellular energy production and repair, making it integral to skin health. 

Here are the top health benefits of NAD+ for skin health and how it supports a vibrant complexion:

1. Boosts DNA Repair

NAD+ plays a pivotal role in activating enzymes, such as PARPs (poly(ADP-ribose) polymerases),4 which are essential for repairing DNA damage caused by harmful UV rays and environmental pollutants. This repair process helps maintain the structural integrity of skin cells, reducing the risks of photoaging, pigmentation issues, and even skin cancers. By restoring damaged DNA, NAD+ promotes smoother, healthier skin.

2. Enhances Cellular Energy Production

Your mitochondria, known as the powerhouses of cells, rely on NAD+ to generate ATP, the energy currency of cells. Adequate NAD+ levels ensure efficient energy production,5 allowing skin cells to regenerate more effectively and repair damage. This energy boost rejuvenates the skin, resulting in a glowing, refreshed appearance.

3. Activates Sirtuins for Cellular Longevity

Sirtuins are proteins that regulate stress responses, inflammation, and aging processes in cells. These proteins depend on NAD+ to function. By activating sirtuins, NAD+ minimizes inflammation, enhances skin elasticity,6 and delays cellular aging. The result? Skin that looks and feels younger, longer.

4. Strengthens the Skin Barrier

NAD+ supports the synthesis of vital proteins and lipids that fortify the skin’s natural barrier. This barrier plays a crucial role in locking in moisture and protecting against environmental aggressors like toxins and bacteria. By maintaining a robust skin barrier, NAD+ helps prevent dryness, irritation, and premature aging, ensuring a smoother, more resilient complexion.

5. Reduces Oxidative Stress

Environmental factors, including pollution and UV exposure, produce free radicals that damage skin cells. NAD+ aids in neutralizing these free radicals7 by supporting antioxidant pathways. This reduces oxidative stress, a key contributor to wrinkles, dullness, and other signs of aging.

These benefits make it clear: NAD+ is a cornerstone for maintaining a radiant, youthful complexion as you age. By supporting cellular repair, energy production, and overall skin health, NAD+ empowers your skin to look and feel its best, no matter your stage in life.

Does Topical NAD+ Work for Skincare?

An image of a matured woman applying skin care

The potential benefits of topical NAD+ in skincare have sparked interest, but research shows mixed results primarily due to its large molecular size. NAD+ is a relatively large molecule, making it difficult to penetrate the skin barrier effectively when applied topically.

The skin’s barrier is highly selective, meaning that only smaller molecules can typically pass through to deeper layers where they can exert their benefits. This limitation raises questions about whether topical formulations of pure NAD+ can truly deliver the anti-aging and skin health benefits often attributed to NAD+ supplementation.

On the other hand, NAD+ precursors, particularly niacinamide (also known as nicotinamide), have shown more promise in topical applications. Niacinamide is smaller in size and can penetrate the skin more easily,8 making it a more viable option for skincare formulations. 

Studies have demonstrated that niacinamide offers numerous benefits for the skin,9 including enhancing the skin’s barrier function by building keratin, reducing inflammation, and improving overall skin texture. These properties make niacinamide an effective ingredient for treating conditions like acne, redness, and hyperpigmentation. Additionally, as a precursor to NAD+, niacinamide helps promote cellular energy and repair, indirectly boosting NAD+ levels in skin cells.

Despite the potential of topical NAD+ and its precursors, clinical studies specifically assessing the effectiveness of topical NAD+ formulations remain limited. More research is needed to explore how to improve skin penetration and determine the best delivery systems to maximize the benefits of NAD+. Until then, niacinamide remains a more reliable option for those seeking the skin-enhancing benefits associated with NAD+.

Key Takeaway: While topical NAD+ struggles with skin absorption, its smaller precursor niacinamide offers proven skincare benefits through better penetration.

How to Boost NAD+ Levels for Healthier Skin

An image of a woman taking supplement

Maintaining optimal NAD+ levels is crucial for youthful, glowing skin as we age. As NAD+ naturally declines over time, it’s important to adopt strategies that boost NAD+ levels to support skin vitality and reduce visible signs of aging.

Here are effective ways to naturally boost NAD+ levels for healthier, radiant skin:

NAD+ Precursors:

Incorporating NAD+ precursors into your daily routine is one of the most effective ways to raise NAD+ levels. These precursors help stimulate NAD+ production within the body, directly benefiting skin health. Key NAD+ precursors include:

  • Niacin (Vitamin B3): Niacin is a direct precursor to NAD+ and helps in its synthesis. It is widely known for its ability to support skin repair and combat inflammation,10 making it an important nutrient for maintaining smooth, youthful skin.
  • Nicotinamide Riboside (NR):Research has shown that NR supplementation can significantly boost NAD+ levels in the body, which helps enhance mitochondrial function,11 improve skin cell turnover, and support overall skin health. NR has been linked to increased cellular energy, which helps skin cells regenerate faster, contributing to a healthier complexion.
  • Nicotinamide Mononucleotide (NMN): NMN, another powerful NAD+ precursor, works similarly to NR but has unique benefits. Studies indicate that NMN supplementation not only increases NAD+ levels but also enhances mitochondrial function and boosts skin cell metabolism.12 NMN has shown promise in improving the elasticity and resilience of the skin, helping it maintain a youthful appearance.

Our Vitality ↑® NAD+ Booster contains a blend of key NAD+ precursors, including nicotinamide and NMN to help raise NAD+ levels and efficiently support cellular health for skin cell renewal.

SHOP NAD+ BOOSTER

Lifestyle Modifications:

Certain lifestyle changes can also naturally boost NAD+ levels and promote skin health. These strategies not only help elevate NAD+ but also support overall well-being:

  • Regular Exercise:Physical activity is a proven way to enhance NAD+ levels. Exercise increases NAD+ in muscles and other tissues, promoting better metabolic health and vibrant skin. Studies have shown that regular exercise can improve skin elasticity, reduce wrinkles, and enhance the skin’s appearance.
  • Intermittent Fasting: This dietary approach has been linked to increased NAD+ production, likely due to its impact on mitochondrial health and reduced oxidative stress. Research suggests that intermittent fasting promotes the activation of longevity genes and boosts NAD+ levels,13 which can improve skin health and vitality.

Sun Protection:

Protecting your skin from harmful UV radiation is critical in maintaining NAD+ levels and preventing premature aging. UV exposure depletes NAD+ by increasing oxidative stress and causing DNA damage. To combat these effects, it is essential to apply broad-spectrum sunscreen daily, which helps preserve NAD+ levels and protects the skin from photoaging and DNA damage.

Stress Management:

Chronic stress can lower NAD+ levels14 by increasing inflammation and oxidative damage in the body. Engaging in stress-reducing practices such as yoga, meditation, and deep-breathing exercises can help mitigate these negative effects. These activities can not only support your overall health but also help maintain adequate NAD+ levels for healthy, radiant skin.

By adopting a combination of these strategies—incorporating NAD+ precursors like NMN, engaging in regular exercise, protecting your skin from UV rays, and managing stress—you can effectively naturally boost NAD+ levels and promote healthier skin. These steps support the body’s natural processes, helping skin cells regenerate and repair more effectively, ultimately contributing to a smoother, more youthful complexion.

Does NAD+ Help With Menopause Symptoms?

Written by Jinfiniti Science on . 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

An image of an aging woman

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

An image of an aging woman suffering from 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

An image of an aging woman suffering from menopause

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

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 . 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

An image of a man with Alzheimer

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

An image of doctors finding 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.

NMN and NR Compared: Better Together or Choose One?

Written by Jinfiniti Science on . 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

An image of 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.
