What is NMN and how does it work?

NMN (nicotinamide mononucleotide) is a molecule that naturally exists in all living forms. NMN is a precursor to the NAD+ molecule (nicotinamide adenine dinucleotide) and was granted the status of an anti-aging agent.

NAD is the general term for the molecule existing in two forms — NAD+ and NADH, which is the oxidized form of NAD+. Without NAD in the body, people would die in seconds. Among numerous other NMN benefits, it participates in activities such as DNA stability, turning food into energy, regulating circadian rhythms, and slowing down organismal aging.

NMN is not the same as vitamin B3, however, it’s a derivative of vitamin B3, meaning they are similar but have different atomic structures. The atomic difference makes NMN a more effective NAD+ precursor.

Besides NMN, NR (nicotinamide riboside) is another well-known NAD+ precursor and a form of Vitamin B3. Most people prefer NR over NMN due to its lower price. Yet, NR is two steps farther from becoming NAD. At the same time, NMN is considered a direct precursor taking one step to convert into NAD.

Though, as we age, both NMN and NAD+ levels decline to cause the onset of aging-related diseases. Raising NMN and NAD levels naturally through a balanced diet containing NMN foods is possible. Yet, the NMN content in foods may not be enough for NAD+ levels elevation. Thus, NMN supplements can come in handy.

Is it safe to take NMN supplements?

Yes. NMN is generally known to be safe as an anti-aging supplement. According to numerous studies with people and mammals, NMN supplements do not pose any significant health risk. However, sticking to the recommended daily NMN dosage is crucial to avoid side effects.

A clinical study conducted in Japan with 10 healthy men showed that the daily administration of 100, 250, and 500 mg NMN carries no significant adverse effects. The lab results demonstrated lower blood glucose levels and balanced serum bilirubin levels indicating proper liver function.

NMN supplements are widely available in the anti-aging and longevity market with various dosages ranging from 250 mg to 600 mg in a capsule. However, more human clinical trials are needed to assess the safety measures of NMN supplements.

What is the best way to take NMN?

NMN supplementation can be administered via injection, capsules, sublingual tablets, and powder.

The best way to take NMN supplements is in the form of capsules or sublingual tablets. You can also consider taking liposomal NMN to ensure the supplement's bioavailability and protect it from stomach acid.

Although many people prefer pure NMN powder due to its affordability, it’s recommended to consume NMN with resveratrol or TMG (betaine) to increase both the effectiveness and absorption of the supplement.

What does David Sinclair say about NMN supplements?

"When you give the body NMN, the body gets all the necessary components — sugars, phosphate, and Vitamin B3 attached — to make NAD+. Studies with mammals demonstrated that mice supplemented with NMN showed longer lifespan and stamina."

David Sinclair

David Sinclair takes 1000 mg of powder NMN daily. This dose may seem high, however, the dosage is reasonable considering that most of the NMN get destroyed in the stomach acid. To increase the bioavailability and efficacy of the supplement, Sinclair takes his NMN with resveratrol, mixed with olive oil or natural yogurt, in the morning on an empty stomach.

When is the best time to take NMN supplements?

Once you get up in the morning, the NAD+ levels peak in your body. This is the best time to take your NMN supplements on an empty stomach to further enhance NAD+ and energy production during the day. If you are taking your supplement twice a day, consider consuming the second serving after 12–3 p.m. when the second rise of NAD+ occurs. Taking NMN later in the evening can increase your energy and hinder sleep.

How to know if NMN supplements work?

Health and anti-aging effects are only sometimes tangible, making people doubt the results of NMN supplements.

The best method to estimate if your NMN supplements work is doing blood work. It is recommended to test the levels of NAD+ molecules and other longevity genes before and after NMN supplementation to picture the intrinsic changes better.

Most NMN users report health improvements already after a week of the supplementation. Others feel no significant improvements after their first week or even month of NMN supplementation.

The reasons may vary depending on the body, consumption method and time, dosage, and supplement form. You can increase the NMN effectiveness by choosing liposomal NMN, which will also help absorption. If you are considering higher doses, consult your doctor first.

What are the potential benefits of NMN supplements?

The reported health benefits of NMN usage include better sleep, energy boost, and better cognitive function. Numerous studies with mammals and humans showed NMN supplements to be highly potent in increasing central-for-life molecules and inducing the below-discussed health benefits.

Age-related weight gain and NAD+ decline are interconnected. With age, NAD+ gets exhausted, eventually slowing down metabolism and leading to weight gain.

Obesity due to a poor diet and an inactive lifestyle can also lead to declining NAD+ levels. NMN supplementation can increase NAD+ levels, thus suppressing unwanted weight gain.

2. Muscle endurance

One of the most studied longevity genes called SIRT1 (Sirtuin 1) was shown to stimulate blood flow and endurance. With NAD+ decline, SIRT1 activity also declines, leading to low exercise capability and muscle density. Studies demonstrated that regular NMN consumption can increase NAD+ levels consequently enhancing SIRT1 activity and positively affecting muscle endurance.

3. Increased sleep quality

Taking NMN early in the morning and the afternoon can regulate circadian rhythms. It may also help to fall asleep faster and sharpen the cognitive function the other day.

4. Boosted brain function

Proper oxygen supply and cerebral blood flow slow down with age, SIRT1, and NAD+ decline. Studies with people having Alzheimer's disorder and aged mice showed that NMN supplementation raises NAD+ and SIRT1 activity in the brain improving cognitive function.


As of October 11, 2022, beta-nicotinamide mononucleotide (Β-NMN) is under an investigation as a potential new drug by the FDA, meaning that it might lose its dietary supplement status. However, until retailers haven’t officially received a warning letter, they continue with distribution of the NMN products.
