10 Best Nicotinamide MonoNucleotide Supplements: Reviews 2023

NMN stands for Nicotinamide MonoNucleotide, a molecule naturally occurring in all life forms. NMN is the direct precursor of the essential molecule nicotinamide adenine dinucleotide (NAD+) and is considered a key component to increase NAD+ levels in cells.

NMN is a precursor to NAD+, or nicotinamide adenine dinucleotide, meaning it becomes NAD+ through a series of chemical transformations. NAD+ is a critical found in every cell of your body, but levels of NAD+ naturally fall with age, making it — and NMN, as a result — crucial.

However, NMN is like a large bed that movers are trying to get through a door: It doesn’t enter the cell easily. One way for NMN to enter the cell is for it to chemically transform into another molecule (called nicotinamide riboside, or NR) before it can enter the cell. NR has earned a name for itself as a highly efficient precursor to NAD+ and can enter the cell as is. NMN, meanwhile, sometimes becomes NR before entering the cell, where it chemically transforms back to NMN and then ultimately becomes NAD+.

We've learned that NR leads to NAD+ and that it also has its own pathway that bypasses various steps other NAD+ precursors have to take. In early 2019, though, new research revealed NMN might only have to become NR for certain cell types, as NMN can enter cells in the small intestine of mice. It’s unclear whether or how this will translate to humans, if at all, but it’s teed up NMN as the newer kid on the block, making many wonder: How does it stack up against NR?

NR vs NMN Molecule

Pitting NR and NMN against each other is, for now, somewhat of a moot point because the two molecules have never been studied side by side in humans. The biggest, and most obvious, difference between NMN and NR is size. NMN is simply larger than NR, meaning it often needs to be broken down to fit into the cell. NR (Nicotinamide Riboside), when compared to other NAD+ precursors (like nicotinic acid or nicotinamide) reigns supreme in efficiency.

But give NMN a new door, one it can fit through, and it’s a whole new game. This is where cellular transporters come into play. Transporters are proteins that are doors on the cell; they allow molecules to enter the cell without needing to chemically transform.

Research from Shin-ichiro Imai, M.D., Ph.D., a professor of developmental biology at Washington University in St. Louis, identified a transporter that allows NMN to get into the cell without converting to NR. The catch? The transporter is only on cells located in the gut of mice and only works in the presence of sodium ions. NR, however, has been shown to enter cells in the liver, muscle, and brain tissue of mouse models. To date there is not yet evidence that these mouse studies can be extrapolated to humans. But again, the two have never been matched up against each other in a way that can truly identify one as superior to the other.

As research grows, it is likely to become clearer that NMN and NR may have differing benefits depending on the part of the body and their use. Where NMN transporters are found, they could make one more preferable over the other. NMN has also been found to improve insulin activity and production which could help to accelerate metabolisms and make the body more glucose tolerant.

What Does NMN Supplement Do?

In numerous studies, supplementation with NMN has increased NAD+ biosynthesis, suppressed age-related adipose tissue inflammation, enhanced insulin secretion and insulin action, improved mitochondrial function, improved neuronal function in the brain, and more. Here, we look at the science behind NMN, its stability, possible pharmacokinetics, transport, function, and ability to induce biosynthesis of NAD+.15 Supplementing NMN may be an effective nutraceutical anti-aging intervention, with beneficial effects on a wide array of physiological functions.

What Foods Contain NMN?

NMN can be found naturally in broccoli, cabbage, cucumber, edamame and avocado.

Best NMN Supplements 2023

Although there are many Nicotinamide MonoNucleotide supplement customer reviews on many online sites, we have sifted and curated some of the helpful ones below. Check out below the best NMN supplements available online.

1. Double Wood NMN Supplement


- Most generic NMN supplements degrade in less than two months and need to be kept refrigerated due to its short shelf life. Double Wood NMN is fully stabilized and do not need refrigeration. Their process of stabilization ensures that the NMN does not deactivate before it reaches your cells.
- Made in the USA
- GMO-Free 

Double Wood NMN Supplement Review
I've been using resveratrol (Jeuness) for 3.5 years, resveratrol was discovered by Dr David Sinclair (Harvard Medical School) discovered in 1992. No longer get cold. However, I'm still get tired due to aging, I believe. And getting worse lately when I've been working hard. So I started looking and noticed Dr Sinclair's book titled Lifespan: Why We Age—and Why We Don't Have To. From which I learned NMN. Then I ordered 1 bottle of NMN (Underwood). I take 4 capsules per day. Label says you can take 2-8 pills. The first week I felt less tired, but wasn't so sure it is due to NMN or something else. The second week, I started running instead of walking, so even I'm shocked! I haven't felt so hungary and energetic for the past decade! So it has to be NMN that worked!!
While I continue using resveratrol at the same time, I feel NMN makes you feel much more energetic. Can't comment longevity yet, but possible, even with NMN.

Amazon Best Sellers: #14 in Vitamin B3 (Niacin) Supplements.

Question: Nmn needs to be refrigerated and kept out of the light. true? typically how old is the product at shippment? thanks
Answer: NMN only needs to be refrigerated when mixed into a solution. I assume you heard Dr. Sinclair mention this and he was referring to his NMN / Walter solution he would give to mice. He was not talking about stabilized NMN powder. We have performed third party tests on this product 6-12 months after production showing it is stabilized and there is no break down in the molecule.

2. TRU Niagen NAD+ Booster Supplement



TRU Niagen NAD+ Supplement comes in 3 sizes:

Amazon Best Sellers: #1 in Vitamin B3 (Niacin) Supplements.

- Technically, Nicotinamide Riboside is not the same molecule as NMN but they are both NAD precursors and are categorised under Vitamin B3 (Niacin) supplements by Amazon.com. Since, TruNiagen is the #1 best seller, we have decided to feature them as part of the best 10 list.
- ChromaDex markets TruNiagen, which is based on its branded Niagen ingredient, which is a form of nicotinamide riboside (NR), the form of nicotinamide that actively crosses into the cell to participate in the NAD+ pathway. 
- Reduces the cellular effects of aging by elevating NAD+, a key coenzyme your body uses for healthy cellular metabolism.
- Nicotinamide Riboside for Energy, Metabolism, Vitality, Muscle Health, Healthy Aging, Cellular Repair 
- Unlike NMN, the key ingredient Niagen was successfully notified two times as an NDI (New Dietary Ingredient) and reviewed as GRAS (Generally Recognized As Safe) under the United States notification programs.
- There are many cheaper alternative sources to buy NMN today, but are you getting what you paid for? If the price for NMN is too good to be true, it probably is not NMN.
 
"While this is not a scientific review I have been taking Niagen in one form or another non stop for several years. I have been gradually increasing my doses with what I can only describe as a profound effect. Without a doubt I feel younger than 46. I also think I look younger than most people my age. I certainly don't feel my age and have a ton of energy every single day. I also try to eat plenty of vegetables with lots of non meat proteins along with limited meat consumption. I am not a health nut but basically try to stay away excess sugars and processed foods whenever I can. I also do a hard bike ride once or twice a week. I think this also helps the entire aging process some." - Amazon

Nutricost Niacinamide Review
After a recent news article about this being a favorite supplement in Australia for sun damage protection, I asked my dermatologist about it. She said it might help prevent me getting as many 'barnacles' as she calls them. You know, those nasty, old-age, sun-damage, crunchy brown or white patches all over your body. (I have many). I'm still on my first bottle but after about two weeks the most amazing thing happened. I happened to scratch an area near one of my barnacles and it just flaked off in my hand. Since then, many more have succumbed. Not all; just some. But I'm happy. Even one less of those ugly bumps is an improvement.

Toniiq NMN Review
I have been using Toniiq NMN along with Resveratrol for about 7 and a half months now. I started taking these for longevity purposes after reading about them in Lifespan. Unexpectedly, I started to see my male pattern baldness reversing about 4 months in; I was not expecting this. Based on the regrowth process speed, it appears I'll reverse 8 years of hair loss in less than a year! My barber is totally floored that hair follicles can come back to life. I can only assume the cells in the rest of my body are rejuvenating as well.

I had been taking the NMN in pill form, but the powder seems to be a much better value. It has a slight tart flavor which I actually enjoy. I've only been using this new form for a short time, but I expect to continue to see the same results.

6. Peak Performance NMN supplement + Resveratrol

peak performance nmn resveratrol


Not all NMN supplements are created equal! Many supplements come with just NMN, which by itself is less effective to produce higher levels of NAD which the body needs to prevent cellular degeneration as we age. Peak Performance combines NMN with Resveratrol. Resveratrol works synergistically with NMN as it acts as an accelerator to produce better results in DNA repair.
- Published in Pharmacology Research and Perspectives, Jiang and colleagues from Macau University of Science and Technology in China demonstrated that combining NMN with resveratrol increases NAD+ levels in heart and skeletal muscle of mice significantly more than NMN alone.
- Anti Aging = NMN + Resveratrol! Our cells use NAD+ to produce energy and to activate proteins that repair damaged DNA. Scientists believe that the decline of NAD+ as we age results in many health-related problems. To sustain healthy levels of NAD+ we can supplement this with its precursor, nicotinamide mononucleotide (NMN) . When combined with Resveratrol this supplement becomes even more powerful. Great for cellular + DNA repair, muscle endurance and strength, vascular health and blood flow.
- What's in your supplement? - Many supplements on the market use standard formulas that may contain cheap fillers and sometimes questionable ingredients. All of our ingredients are carefully chosen and 3rd party tested for purity.
- Vegan & Allergy Free - Free Of Soy, Milk, Egg, Shellfish, Corn, Wheat & Peanuts. Contains NO Gluten or Preservatives. Manufactured Under The Highest Quality GMP Regulations and USA Standards.

Review - My husband and I are in our 60s and have been taking these capsules for a few weeks. We both started with 2 capsules daily and experienced an increase in energy and in focus. We also both had trouble remaining asleep at night and had strange dreams. We have decreased our consumption of the capsules to one per day and have had a resolution to the sleep problems. We both continue to enjoy an increase in energy and in focus. We have reordered this Thorne product and are very satisfied with the results. It would be best to start with one capsule per day and work up from there until you find your own correct dosage.

Elixr


Amazon Best Sellers: #11 in Resveratrol Nutritional Supplements.

Amazon Reviews: 4.3 out of 5 - more than 290 global ratings

- Toniiq products are produced in a GMP-certified and NSF-approved state-of-the-art manufacturing facility right here in the USA.
- Meet ELIXR, the First of Its Kind NMN and Resveratrol Combination - Toniiq set out to create one of the very first Resveratrol and NMN supplement capsules on the market; something that was impossible until very recently with breakthroughs in nicotinamide mononucleotide blending and stabilization technology.
- The Role of NAD+ and Sirtuins in Healthy Aging and Longevity - If the human body were a rocket ship, sirtuins (a type of protein involved in regulating essential biological processes) can be thought of as "mission control", while NAD+ (a critical coenzyme essential to the fueling a number of those functions) can be thought of as "fuel". Both work synergistically to support healthy aging.
- Resveratrol, NMN, and Trimethylglycine - Both nmn nicotinamide mononucleotide and resveratrol are being closely studied for their supporting effects on NAD+ and sirtuins respectively. Trimethylglycine has also been added to this formula at a 1:1 ratio to provide methylation support.

Important safety note: Resveratrol is not suitable for people undergoing blood-thinning medication.

Chromadex NMN Supplement Test Report: 64% of NMN Supplements Fail Tests

ChromaDex NMN Report (Oct 2021): Supplement manufacturer ChromaDex alleges that testing has revealed that more than half of NMN anti aging supplements being sold on Amazon contained almost none of the bioactive molecule.

ChromaDex markets TruNiagen, which is based on its branded Niagen ingredient, which is a form of nicotinamide riboside (NR), the form of nicotinamide that actively crosses into the cell to participate in the NAD+ pathway. Boosting this pathway, and thus maintaining cellular function at a lively, youthful level, has become a prominent theme in recent anti aging research.

Credit: ChromaDex

* The same distributor (SerumLab S&C International LLC) was listed on the product packaging from 10 of the 22 product brands.

Some researchers have argued that a transporter exists for NMN too, which is something that ChromaDex disputes. It claims that NMN must first be converted into NR in the blood before it can be used by the cells.

In the several years since the NMN transporter discovery was asserted, the NAD+ anti aging field has become crowded with NMN based supplements all seeking a piece of the pie created by ChromaDex and its competitor and one time customer Elysium. (The two companies have been locked in various patent infringement and breach of contract suits for several years.)

Last fall, ChromaDex obtained 22 samples of NMN products being sold on Amazon. Of these, 14 claimed to contain 500 mg of NMN. A further two products claimed 300 mg on the label; five claimed 250 mg and one product claimed 125 mg.

Only one of the 500 mg products came close to meeting label claim. It had 456 mg of NMN. All of the other 13 products in the 500 mg group either came in at below reporting limit (BRL, defined as less than 1% of the stated amount) or, in the case of 3 products, no NMN was detected at all.

Almost all of the rest of the products performed better, having at least 88% of the label claim. A lone 250 mg product was identified as BRL.

In summary, ChromaDex said that 64% of the products tested contained less than 1% of the stated amount of the active ingredient, which should give consumers pause, the company said.

"While this is a limited snapshot of the vast NMN finished product landscape, it does provide a glimpse into the high variability of product quality that is available... According to this study, the majority of the products one might purchase online contain such a small amount of NMN that there would be no clinical benefits achieved from the dose. Another concern with these adulterated products is that the actual contents are not known and could pose a risk to the user," the company said in a statement.

Editor's Note: In February 2022, another third-party investigation uncovered tens of thousands of fake supplements sold on Amazon. Many of these included NMN.
