What Are NMN and NAD?

NMN (nicotinamide mononucleotide) is a compound that helps the body produce NAD (nicotinamide adenine dinucleotide), a coenzyme vital for energy, metabolism, and cell repair. NAD levels decline with age, which may contribute to fatigue and slower metabolism. 

Studies suggest that NMN supplements can help restore NAD levels, supporting muscle endurance, brain function, and overall health (1).

While the body naturally produces NAD, factors like aging, stress, and poor diet speed up its depletion. Some foods, like broccoli and avocados, contain NMN, but in amounts too small to make a difference. 

That’s why many people take NMN supplements as a convenient way to support their NAD levels and promote healthy aging.

How Effective Are NMN Supplements?

NMN supplements have gained attention for their potential role in supporting cellular health and healthy aging, but how well do they actually work? While research is still in the early stages, some human studies suggest NMN may have real benefits.

A 2022 study published in GeroScience—a randomized, double-blind, placebo-controlled trial (the gold standard in research)—tested NMN on middle-aged and older adults (2). 

Participants taking 250 mg of NMN daily saw a significant increase in NAD+ levels, which plays a critical role in energy production, metabolism, and DNA repair.

Beyond NAD+ production, the study found that NMN supplementation may help with muscle endurance and physical performance. Participants taking NMN showed better strength and stamina compared to the placebo group. 

Similar findings have been observed in a 2021 study on amateur runners, which linked NMN to improved oxygen use in skeletal muscles (3).

There’s also emerging evidence that NMN could support brain health. The GeroScience study noted improvements in memory, focus, and mental clarity among NMN users, suggesting potential neuroprotective effects. 

Additionally, researchers observed reduced markers of inflammation, which is linked to many age-related conditions. While these findings are promising, NMN research is still developing. 

The FDA has not approved NMN to prevent or treat any disease, and long-term studies are needed to confirm its benefits. If you’re considering NMN, it’s best to consult a healthcare provider—especially if you have existing health conditions.

Are NMN Supplements Safe?

NMN supplements are generally safe for most people, with no serious side effects reported in studies. However, long-term effects are still being researched.

Human trials have shown that NMN is well-tolerated, even at doses up to 1,200 mg per day. Some users report mild side effects like nausea, digestive discomfort, or headaches, but these are rare (4).

One area of concern is NMN’s potential link to cancer growth. Some studies suggest that while NAD supports healthy cells, it may also fuel cancerous cells if they are already present (5). 

However, other research indicates that NAD can actually help prevent certain types of cancers. It’s a gray area that needs more studies (6).

For now, if you have a history of cancer or are currently undergoing treatment, it’s best to talk to your doctor before taking NMN. Otherwise, for the average person, NMN appears to be a safe and promising supplement for cellular health.

How NMN Supplements Work

NMN supplements work by increasing NAD levels in the body, which helps fuel cellular processes like energy production, DNA repair, and metabolism.

When you take NMN, your body quickly converts it into NAD, usually within 15 minutes (7). This NAD then supports mitochondria, the powerhouses of our cells, helping them function more efficiently. 

Studies suggest that restoring NAD levels may improve endurance, brain function, and overall vitality (8).

Absorption plays a huge role in how effective an NMN supplement is. Traditional capsules have to survive stomach acid before reaching the intestines, where absorption happens. 

Some brands use enteric-coated capsules to protect the NMN, while others use sublingual powders, nasal sprays, or liposomal formulations for faster and more direct absorption.

While sublingual and liposomal NMN are popular for their faster absorption, capsule-based NMN supplements remain the most well-studied and widely used form. 

Research shows that NMN is effectively absorbed through the intestines, where a dedicated transporter helps deliver it into the bloodstream (9). Some brands use enteric-coated capsules to protect NMN from stomach acid, ensuring better stability and absorption. 

For those looking for a convenient, reliable, and research-backed option, capsule NMN supplements are a great choice.

Potential Health Benefits of NMN Supplements

Aging is inevitable, but researchers are exploring ways to slow down its effects. NMN (nicotinamide mononucleotide) is gaining attention for its role in replenishing NAD+, a molecule that declines with age and supports energy, metabolism, and cellular repair.

According to Dr. Elena Martin, MD, an anti-aging researcher, early studies on NMN show promising results in areas like energy metabolism and muscle function. “However, we still need larger, long-term trials to confirm these benefits in diverse populations.” In other words, while the science is encouraging, more human research is needed before drawing firm conclusions.

That said, current findings suggest NMN may support healthy aging, improve muscle endurance, aid metabolic health, and play a role in brain function. Here’s what the research says so far:

May Support Healthy Aging

Some research suggests NMN supplementation might help slow certain signs of aging by maintaining NAD+ levels. 

A study found that NMN-fed mice had improved metabolism, stronger muscles, and better endurance compared to those that didn’t receive it (10). Whether this translates to humans in the same way is still being studied.

Might improve muscle endurance and performance

A small study on amateur runners found that NMN supplementation increased aerobic capacity, likely by improving how efficiently muscles use oxygen (11). This could be helpful for people looking to maintain physical performance as they age.

Could play a role in metabolic health

Early research indicates NMN may help with insulin sensitivity and energy metabolism. A study found that mice given NMN showed improved glucose metabolism and reduced fat accumulation (12). 

In humans, a small trial on prediabetic women found that taking 250mg of NMN daily for ten weeks helped muscles process sugar more effectively (13).

Might support brain health

Some animal studies suggest NMN could have neuroprotective effects. Research in rodents has shown improved memory and cognitive function in models of Alzheimer's disease (14). While this is promising, human trials are still in the early stages.

May help with energy levels

Since NAD+ is involved in mitochondrial function (aka the tiny power plants inside your cells), NMN might help with energy production. 

Anecdotal reports suggest that some people notice better stamina and less fatigue after taking NMN, though this hasn’t been widely studied in humans.

Could support heart health

Some animal studies suggest that NMN may help maintain vascular function by keeping blood vessels flexible. 

A study found that aged mice given NMN had improved blood flow and reduced markers of cardiovascular aging (15).

Are There Any Side Effects of Taking NMN Supplements?

For most people, NMN supplements are well-tolerated with no serious side effects reported in human studies. Research so far suggests that NMN is safe at doses ranging from 100 mg to 1,200 mg per day, with no major concerns about toxicity. 

That said, quality matters—low-quality supplements or unknown ingredients could pose risks, so choosing a reputable brand is key.

While NMN appears to be safe, let’s break down what the research says:

• Keio University (2020) – A three-year human toxicity study tested 100 mg, 250 mg, and 500 mg of NMN daily and found no negative effects on heart rate, blood pressure, or other physiological markers (16).

• University of Tokyo (2021) – A 12-week trial with 250 mg of NMN daily found no reported side effects, reinforcing its safety profile (17).

• Washington University School of Medicine – A 10-week study on NMN at 250 mg per day also showed no adverse effects, only positive outcomes (18).

• Amateur Runner Study (2021) – Participants took 300 mg, 600 mg, or 1,200 mg per day, and while the study focused on performance, no negative effects were noted at any dosage (19).

• Recent Clinical Trial (2023) – Tested placebo, 300 mg, 600 mg, and 900 mg doses and found no toxicity signs at any level, with participants in the 900 mg group reporting the most benefits (20).

Of course, everyone’s body reacts differently. Some people may experience mild digestive discomfort, nausea, or headaches when first starting NMN—common with many supplements as the body adjusts. If you have existing health conditions or take medications, it’s always smart to check with a doctor first.

The biggest risk? Buying NMN from shady brands. If a company doesn’t provide third-party testing, hides ingredient details, or sells NMN at a suspiciously low price, that’s a red flag. Stick with brands that are transparent about sourcing and manufacturing—your health is worth it.

What to Look for When Buying NMN Supplements

Dose 

At the time of writing, there is no official recommended dose of NMN for adults. However, the best NMN supplements on the market base their dosages on the amounts used in research studies.

Recent human trials have tested various doses, providing helpful insights:

• A 2023 study tested doses of 300mg, 600mg, and 900mg on healthy, middle-aged adults. All doses boosted NMN levels, with 600mg showing the greatest improvement in physical performance. (21)

• Other research suggests that doses as low as 250mg can effectively boost NAD+ levels. (22)

Generally, the best NMN brands include a dose range of 500mg–750mg, considered optimal by most experts. This range strikes a balance between effectiveness and safety. 

However, the ideal dose may vary from person to person, and more research in the coming years will refine these recommendations.

Purity 

High Purity: Look for products with high purity levels, ideally 99% or higher, to minimize contaminants and ensure efficacy. A purity level of >98% is generally recommended. Check for purity claims on the label or product details. 

Lower-quality NMN may have fillers, contaminants, or other substances that could reduce the effectiveness of the supplement.

Avoid Impurities: Look for products that emphasize minimal to no impurities, especially those that might interfere with absorption or efficacy.

No additives

When supplement ingredients are manufactured and packaged into pills or tubs, they have to go through various machinery to allow this to happen efficiently. 

To prevent the powder from clumping together or clogging up the machinery, flow agents are added (also known as excipients). They are inactive ingredients that are not meant to exert any function aside from helping the manufacturing process. 

You can find out which excipients are used by checking the label and looking for the “other ingredients” section. 

The most common you’ll see are magnesium stearate a silicon dioxide. Although they are meant to be inactive, some people have intolerances, and it's not uncommon to have gastrointestinal upset, particularly toward magnesium stearate. 

The best NMN supplements use natural flow agents made from rice flour. 

3rd party testing

When purchasing NMN supplements, it's essential to look for third-party testing, which ensures that an independent laboratory has tested the product for ingredient purity, dosage accuracy, and the presence of potential contaminants like bacteria, fungus, and heavy metals. 

This added layer of verification helps ensure the supplement is safe, effective, and free from harmful substances.

Reputable brands typically have their products tested by independent labs to confirm the potency and purity of the NMN, often providing certificates of analysis (COA) either on their websites or upon request, allowing you to verify the product’s quality with confidence.

Red flags to avoid:

• No NMN purity listed

• Missing GMP certification

• Prices below $1 per 100 mg (may indicate low quality or synthetic NMN)

Manufacturers GMP certificate

GMP stands for good manufacturing practice. It is a certification process whereby manufacturers have to adhere to strict manufacturing standards. 

This means regular inspections by an independent 3rd party are required to maintain that the standards are being adhered to.  

There is a lot of confusion around this topic because the brands themselves do not have GMP certificates. It is the manufacturing facility that is certified. 

For added measure, you can ask the NMN brand of your choice to send over the GMP certificate of their manufacturer.

Some brands will slap a GMP logo on their label, but this doesn’t guarantee they are made in a GMP facility. Anyone can print an icon and place it on their label!

Additional ingredients

NMN isn’t the only NAD+-boosting ingredient out there. The best NMN supplements often combine NMN with other longevity-promoting compounds to create a more potent, comprehensive formula.

Resveratrol is a popular addition, known for its potential to enhance the benefits of NMN and support overall cellular health.

What Is the Ideal NMN Dose?

The optimal NMN dosage depends on individual needs, but general guidelines suggest 250–500 mg per day for general health, 600–900 mg per day for aging support and athletic performance, and up to 1,200 mg per day under medical supervision. 

Factors like age, body weight, and health status influence dosage needs. Older adults or athletes may benefit from higher amounts, but more is not always better. 

Since NAD+ production naturally declines with age, many people take NMN to support energy, metabolism, and longevity. Always consult a doctor before using higher doses.

What Time of Day Should You Take NMN?

Longevity expert Dr Daivd Sinclair takes NMN in the morning. He states that he does this because there is a natural rise in cellular NAD production and SIRT1 activity in the mornings.

Therefore, he suggests that taking NMN in the morning to match this natural rise in cellular NAD production as it makes the most sense. 

With that said, it has not been formally examined in research studies. The best time of day to take NMN supplements is still up for debate and the recommendation may change as we learn more over the years.

Frequently Asked Questions

Is Beta NMN the same as NMN?

Yes, Beta NMN (β-NMN) and NMN are the same compound. The "beta" form refers to the active structure used by the body. The alpha form is inactive, making β-NMN the standard form found in supplements.

Is Liposomal NMN better than regular NMN?

There’s no evidence that liposomal NMN is superior. NMN is water-soluble and well-absorbed from the gut. Some brands claim NMN has poor absorption, but human and animal studies confirm it is efficiently absorbed without needing a liposomal form.

Is NMNH better than NMN?

NMNH (the reduced form of NMN) also raises NAD levels, but research is limited. One study suggests it may be 5-10x more potent than NMN at increasing NAD (23), but more data is needed before conclusions can be drawn.

Is NR better than NMN?

NR converts to NMN before becoming NAD+, meaning NMN is one step closer to NAD. Scientists generally consider NMN more effective since most NAD research is done on NMN, not NR. While NR is a smaller molecule, studies confirm NMN is easily absorbed and effective at doses as low as 250mg (24).

Can I take NMN while fasting?

Yes. While NMN is often recommended in the morning, there’s no evidence that fasting affects its benefits. You can take NMN during your eating window without any major impact.

Should NMN be taken with or without food?

• With food: May enhance absorption, especially with fats, and reduce stomach discomfort.

• Without food: Allows for faster absorption and may enhance energy benefits.

• Either way, NMN is well-absorbed, so choose what suits you best.

How should NMN supplements be stored?

Store NMN in a cool, dry place away from sunlight. Early NMN formulations were unstable, but modern versions are much more heat and UV-resistant. High-quality NMN is usually packaged in opaque bottles for extra protection.

How long does it take for NMN supplements to work?

• Short-term: NAD+ levels rise within 30-60 minutes, with users noticing more energy and physical endurance within days or weeks.

• Long-term: For benefits like better metabolism and heart health, consistent use for several weeks to months is recommended. A 12-week study showed significant NAD+ increases and metabolic improvements.

How can I tell if NMN supplements are working?

The most accurate way is to measure NAD+ levels and inflammation markers with a biological age test before and after supplementation. Many users report more energy, better sleep, and improved workouts, but these effects are subjective. Lab testing provides objective proof of NMN’s benefits.

Conclusion

Finding the right NMN supplement doesn’t have to be overwhelming, especially with misleading marketing claims.
