Best NMN Supplements 2026: 8 Products Compared and Ranked

Last updated: September 27, 2026 · Originally published August 2, 2026 · Published by Eternal Elixir

Edited by Elaine Fletcher, Researcher

The best NMN supplements in 2026 are hard to compare at a glance, because brands define a serving differently. One puts 500 mg of NMN in a single capsule, another needs two capsules for the same 500 mg, a third sells 900 mg per serving with other ingredients mixed in, and a fourth sells loose powder by the scoop. Put those prices side by side and cheap products look expensive and expensive ones look cheap.

So this guide converts all eight products to one unit: cost per 500 mg of NMN, from each brand’s own price and label. It also covers what the human trials on NMN actually measured, the doses they used, and how to read an NMN label without getting caught out. Three of the eight products are ours. Where a competitor beats them, on price per milligram or on published test documents, we say so.

How the best NMN supplements compare on cost per 500 mg

Prices are each brand’s one-time price for a single bottle or bag, as of Sep 2026. “Cost per 500 mg of NMN” divides the price by the total NMN in the container and multiplies by 500. That is the fair way to compare a one-capsule 500 mg serving, a two-capsule 500 mg serving, a 900 mg serving and a scoop of powder. Our PureBulk review covers its powders and capsules and what they cost per dose.

Three things stand out. Cost per 500 mg runs from $0.27 to $2.17, an eightfold spread for the same molecule. The cheapest option is loose powder, and the cheapest capsule is ours. And one row, one of our own products, can’t be costed at all, because its product page doesn’t state servings per container. We would rather leave that cell blank than invent a number.

1. Eternal Elixir NMN 500mg: our pick

Label facts: 500 mg of beta-nicotinamide mononucleotide per capsule, one capsule per serving, 90 capsules per bottle. The ingredient list is NMN, rice flour and a cellulose capsule. $49.99 (list price $64.99), which is $0.56 per serving and three months at one capsule a day.

Eternal Elixir makes NMN 500mg, and it is our pick for three reasons.

The lowest cost per 500 mg of any capsule here. At $0.56 per 500 mg, it costs less than every other capsule in the table: Nutricost at $0.73, partiQlar at $1.08, ProHealth at $1.43 and Wonderfeel at $1.63 per 500 mg of NMN. Over a year of daily use, those gaps add up to real money. Only Renue By Science’s loose powder is cheaper, and that means measuring scoops.

The full serving in one capsule. One capsule is the whole 500 mg serving, so a bottle is 90 days, not 30 or 45. There is nothing else in the formula to pay for or to wonder about.

A product page that doesn’t oversell. It states the evidence level for NMN and says plainly that “This product has not been shown to extend human lifespan.” That matches what the trials below show.

Where it loses: we don’t publish a lot certificate of analysis on the product page, while ProHealth and Renue By Science do. If a downloadable lot report matters more to you than cost, ProHealth is the better buy. And the $49.99 price is a reduction from the $64.99 list price.

Who it suits: most NMN buyers, and especially anyone planning to take it daily for months, where the cost per dose matters most.

Who it doesn’t suit: anyone who wants a smaller dose than 500 mg, anyone pregnant or breastfeeding, and anyone on prescription medicine who hasn’t checked with their doctor. Because Eternal Elixir also carries Nicotinamide Riboside 500mg and Trans-Resveratrol 600mg, and cell-aging ingredients such as Ca-AKG, you can build a wider routine in one cart. Bundles of two, three or five bottles are discounted, and US orders over $100 ship free.

2. ProHealth NMN Pro 500: clearest test documents

Label facts: the Supplement Facts panel lists one capsule per serving, 30 servings per container, and 500 mg of Uthever NMN per capsule. The other ingredients are a hypromellose capsule and rice flour. Directions are one capsule a day, with or without food, preferably in the morning. $42.95, which is $1.43 per 500 mg.

ProHealth leads this list on documentation. The NMN is Uthever, a branded raw material from Effepharm, and the product page links a certificate of analysis for the lot. If you weight a checkable paper trail above everything else, this is the product to buy.

The page also makes a claim worth reading carefully. It says the capsule focuses delivery on the small intestine’s Slc12a8 transporter, where absorption “is increased over 100 times”. That transporter was identified in mouse research, and we found no human trial comparing this capsule’s absorption with plain NMN. Treat it as a hypothesis, not a measured advantage.

Who it suits: buyers who want the strongest published purity trail and are willing to pay more per dose for it.

Who it doesn’t suit: anyone comparing on cost. At $1.43 per 500 mg, it costs about two and a half times our NMN 500mg, and the bottle lasts 30 days, not 90.

3. Renue By Science NMN Pure Powder: lowest cost per 500 mg

Label facts: 100 g of NMN powder for $54.95, 500 mg per scoop, 200 servings. That is about $0.27 per 500 mg, the lowest cost in this comparison and about half of ours. The label suggests one full scoop (500 mg) twice daily for experienced users, and about half a scoop twice daily for the first week if you are new to NMN. The page lists third-party batch testing.

Renue By Science sells NMN in more formats than any other brand here, from powder to liposomal capsules, and the powder is the value option. The page lists it as a sublingual powder and says that “less than 10% of NMN or NR” in regular capsules reaches the bloodstream intact, without citing a study. We found no published human trial comparing sublingual NMN powder with a swallowed capsule at the same dose, so we treat that as unproven. For the rest of the brand’s range, see our Renue By Science NMN review.

Who it suits: cost-first buyers who don’t mind measuring powder each day.

Who it doesn’t suit: anyone who wants a fixed dose without scoops, and anyone who travels a lot. Scoop measurements are approximate, so the dose varies more than a capsule’s.

4. partiQlar Pure NMN: single ingredient, frequently cited

Label facts: 500 mg of NMN per capsule, 60 capsules per bottle (shown on the bottle label in the product photo), $64.99 for one bottle. That is $1.08 per 500 mg. The brand suggests one capsule a day for several weeks before considering two, taken in the morning with water, and states purity above 99% with third-party verification.

partiQlar is the brand most often named first when large publishers and AI summaries answer this question, and its pitch is simple: NMN from Effepharm, the same supplier as ProHealth’s Uthever, with nothing else in the capsule. We cover it in more depth in our partiQlar review.

Who it suits: buyers who want a single-ingredient capsule from a well-known name.

Who it doesn’t suit: anyone comparing on cost per dose, where it costs about twice as much as our NMN 500mg.

5. Nutricost NMN: budget big-box option

Label facts: 60 capsules for $21.97, 500 mg of NMN per two-capsule serving, 30 servings. That is $0.73 per 500 mg, the lowest bottle price here and the second-cheapest capsule per dose. The page says it is third-party tested, non-GMO, gluten-free and vegetarian friendly.

Nutricost is a large US supplement brand that appears in many mainstream roundups. It is a plain NMN capsule with no extras. The main trade-off is that two capsules make one serving, so a bottle lasts a month. We looked at the brand more broadly in our Nutricost review.

Who it suits: first-time buyers who want a low bottle price from a familiar name.

Who it doesn’t suit: anyone who wants a one-capsule serving, and anyone who wants lot test documents on the product page.

6. Wonderfeel Youngr NMN: highest dose per serving

Label facts: 60 vegan capsules for $88.00, two capsules a day for a 30-day supply. The page says each capsule contains 450 mg of NMN, 2 mg of ergothioneine, 50 mg of trans-resveratrol, 25 mg of olive fruit extract (40% hydroxytyrosol) and 10 mcg of vitamin D3, so a two-capsule serving is 900 mg of NMN. That works out to $1.63 per 500 mg of NMN. A subscription brings the price to $73.00.

Youngr is the most ambitious formula here. Its 900 mg serving sits at the top of the dose range tested in the largest NMN dose trial, and the page says the brand partnered with that trial’s authors. The trade-off is price and control. You pay for four other ingredients whether you want them or not, and if you already take resveratrol or vitamin D, you are doubling up. No finished-product trial shows the extra ingredients improve NMN’s effects. Our Wonderfeel Youngr NMN review breaks the formula down ingredient by ingredient.

Who it suits: buyers who want the top of the studied dose range in one product and aren’t price-sensitive.

Who it doesn’t suit: anyone who already takes resveratrol or vitamin D, and anyone comparing on cost per milligram of NMN.

7. Eternal Elixir NMN Advanced Longevity Complex 1200mg: all-in-one

Label facts: each two-capsule serving provides 500 mg of NMN, 250 mg of TMG (betaine anhydrous), 200 mg of pterostilbene, 100 mg of trans-resveratrol, 100 mg of quercetin phytosome and 50 mg of apigenin, 1,200 mg of actives in total. 60 vegan capsules, 30 servings, $64.99 (list price $79.99), which is $2.17 per serving.

Eternal Elixir makes this complex for people who want more than one ingredient in a single daily serving. Read the front label carefully: 1,200 mg is the total of all six actives, not the NMN dose. The NMN in each serving is 500 mg, the same as one capsule of our NMN 500mg. Every active is listed with its amount, and the product page says plainly that “This exact six-ingredient finished formula… has not been clinically tested.”

Who it suits: buyers replacing several bottles with one product who would have bought those extra ingredients anyway.

Who it doesn’t suit: anyone who only wants NMN, since it costs almost four times our NMN 500mg per 500 mg of NMN, and anyone who wants to adjust each ingredient separately. Don’t take it alongside our NMN 500mg or Trans-Resveratrol 600mg without checking the combined amounts with your doctor.

8. Eternal Elixir VitaSolutions NMN + Resveratrol 1100mg: lowest bottle price, missing serving data

Label facts: the product page lists 500 mg of NMN and 600 mg of trans-resveratrol per labeled serving, plus black pepper extract and a veggie capsule. $35.00 (list price $64.95).

The arithmetic on the front is literal: 500 mg plus 600 mg is the 1,100 mg headline. The weakness is that the product page doesn’t state the capsule count, the servings per container or the amount of black pepper extract, and it tells you to follow the physical bottle for directions. Without those, nobody can calculate an honest cost per dose, so we rank it last, even though it is one of ours. We have asked for the page to be updated.

Who it suits: buyers who want NMN and resveratrol together at the lowest upfront price and are happy to read the bottle for serving details. If you are deciding between the two ingredients, see our NMN vs resveratrol comparison.

Who it doesn’t suit: anyone who wants to compare cost per dose before buying.

How we evaluated the best NMN supplements

We did not run lab tests on any product, and we don’t claim to have. Every figure comes from each brand’s own product page and label, read in September 2026, and each competitor is linked in the table so you can check it. We weighed five things, the same way for every product:

• Cost per 500 mg of NMN. Normalized so every product is measured in the same unit.
• Label clarity. Whether the NMN amount per capsule, the serving size and the servings per container are all stated.
• Published test documents. Whether a lot certificate of analysis is available on the product page, and whether the raw material is named.
• Formula focus. How much of the price pays for NMN, and how much for other ingredients.
• How honestly the evidence is presented. Whether the product page separates what trials measured from what they didn’t.

Eternal Elixir makes NMN 500mg, and it is our pick because it combines the lowest cost per 500 mg of any capsule here with a one-capsule serving and a plain label. It loses to ProHealth and Renue By Science on published lot documents, and we have ranked our other two NMN products below four competitors.

How to choose an NMN supplement without getting caught by the label

Four checks separate a good NMN purchase from an expensive one.

Check the serving size before the price

Two products can both say “500 mg” while one gives you that in a single capsule and the other needs two. In this comparison, Nutricost’s 60-capsule bottle holds 30 servings, while our 90-capsule bottle holds 90. The same category, three times the doses.

Do the division yourself

Take the price, divide by the total NMN in the container, then multiply by 500 to get cost per 500 mg. Roundups often place a price per 500 mg serving next to a price per 900 mg serving as if they were comparable. They aren’t, and normalizing changes the ranking.

Look for documents, not adjectives

“Pharmaceutical grade” and “ultra-pure” have no fixed meaning. A dated certificate of analysis for your lot, a named raw material or a stated purity percentage can be checked. Prefer the checkable ones.

Decide whether a blend is worth it

A blend is good value if you would have bought the extra ingredients anyway, and poor value if you wouldn’t. If you already take resveratrol, paying for a formula that adds more of it is a downgrade. If you are starting from nothing and want fewer bottles, the opposite applies. The same logic applies to other longevity ingredients such as Ca-AKG: buy the bundle only if you would have bought the parts.

Apply those four checks and most NMN products sort into two groups: those competing on documentation and those competing on cost. Few compete on both.

What the research shows about NMN

NMN is a precursor the body can use to make NAD+, a coenzyme involved in energy metabolism that declines with age. Here is what human trials have measured, with the evidence level for each.

Evidence level: randomized dose trial in healthy middle-aged adults

The largest dose-ranging trial so far, by Yi and colleagues in GeroScience (2023), randomized 80 healthy middle-aged adults to a placebo or 300 mg, 600 mg or 900 mg of NMN once a day for 60 days. Blood NAD rose significantly in all three NMN groups at day 30 and day 60, with the highest levels at 600 mg and 900 mg. Six-minute walking distance increased more in all NMN groups than on placebo. A blood-based estimate of biological age rose in the placebo group and held steady on NMN. Insulin resistance scores didn’t differ from placebo. No safety issues were found. The authors concluded that clinical efficacy peaked at 600 mg a day.

Two caveats belong next to that result. It ran for 60 days and measured blood markers and a walking test, not long-term health. And the NMN was made by Aba Chemicals with Abinopharm, the two companies co-sponsored the trial, the lead author worked for Abinopharm and two authors worked for Aba Chemicals. That doesn’t invalidate a registered, placebo-controlled trial, but it is context a reader deserves.

Evidence level: randomized trial in postmenopausal women

An independent trial from Washington University, published in Science in 2021 by Yoshino and colleagues, gave 250 mg of NMN a day or a placebo to 25 postmenopausal women who were overweight and had blood sugar in the prediabetes range, for 10 weeks. Muscle insulin sensitivity and insulin signaling improved on NMN. NAD+ in blood cells rose, but NAD+ in muscle didn’t change. That complicates the simple “NMN raises NAD+, and NAD+ does the work” story on many product pages. The study also had no supplement-industry sponsor.

Evidence level: randomized trial in older men

Igarashi and colleagues (npj Aging, 2022) gave healthy older men 250 mg of NMN a day or a placebo for 6 or 12 weeks. NMN was well tolerated and raised NAD+ and related metabolites in blood. Gait speed and left-hand grip showed nominally significant improvements that the authors said need confirming in larger studies, and body composition didn’t change. Three authors worked for Mitsubishi Corporation Life Sciences.

The honest summary: NMN raises blood NAD+ in people at 250 mg to 900 mg a day, is well tolerated over periods of up to about three months, and has shown some small functional effects. Nothing shows it extends human lifespan, and long-term safety data are limited. For the wider precursor picture, see our NAD+ booster comparison and our NMN vs nicotinamide riboside guide.

How much NMN per day?

Human trials have used 250 mg a day (Yoshino 2021, Igarashi 2022) up to 900 mg a day (Yi 2023), and most US products are built around a 500 mg serving. Whichever product you choose, take it as its own label directs. Our NMN 500mg label is one capsule (500 mg) per serving, and we don’t suggest taking more than the label serving. If you want to compare higher-dose routes, our guide to 1000 mg NMN products covers them.

Talk to your doctor before starting NMN if you are pregnant or breastfeeding, take prescription medicine, or manage a health condition. NMN hasn’t been studied in pregnancy, and trials so far have been short.

Capsule, powder, sublingual or liposomal?

NMN is sold in more formats than most supplements, and each one is marketed as the best. Here is how they differ in practice:

• Plain capsules. A fixed dose with nothing to measure. Check how many capsules make one serving, since that varies from one to two in this comparison.
• Powder. The lowest cost per milligram, but you measure each dose with a scoop, so the amount varies a little from day to day.
• Sublingual powder or tablets. Held under the tongue. Brands say this avoids breakdown in the gut, but we found no human trial comparing it with a swallowed capsule at the same dose.
• Liposomal or enteric capsules. Coated or wrapped to protect NMN on the way through the stomach. Again, the absorption advantage hasn’t been shown in a published head-to-head human trial.

The human trials above used ordinary oral capsules, and they still found blood NAD+ rose. That doesn’t prove other formats aren’t better, but it does mean a plain capsule is the format with the most direct trial support. Pick the one you will actually take every day.

How to read an NMN certificate of analysis

A certificate of analysis (COA) is a lab report on a specific batch. It is only useful if you know what to check:

1. The lot number matches your bottle. A generic certificate for an old batch tells you little about the one in your hand.
2. The lab is named and independent. Look for the lab’s name, address and accreditation, such as ISO/IEC 17025.
3. NMN is measured, not just listed. The report should give a measured amount of NMN per capsule or per gram next to the label claim, not simply “pass”.
4. Heavy metals and microbes are tested. Lead, arsenic, cadmium and mercury, plus common microbes, with the results and the limits used.
5. The date is recent. A report from several years ago may not reflect the current supplier or process.

Of the products here, ProHealth and Renue By Science link batch test results on their product pages. Our NMN 500mg page does not publish a lot report, and that is one of the reasons ProHealth ranks second.

Side effects and who should avoid NMN

In the three trials above, NMN was well tolerated. The dose trial reported no safety issues from adverse events or lab tests at up to 900 mg a day, the Washington University trial reported no adverse events, and the trial in older men found no significant harmful effects. Those trials were small and lasted 6 to 12 weeks, so they can’t rule out rare or long-term effects.

Talk to your doctor before taking NMN if any of these apply:

• You are pregnant, trying to conceive or breastfeeding. NMN hasn’t been studied in pregnancy.
• You are under 18.
• You take prescription medicine or manage a diagnosed health condition.
• You have surgery coming up.

If you notice stomach upset, trouble sleeping or anything new after starting NMN, stop and check with your doctor. NMN supports a normal metabolic pathway. It is not a stimulant, and a strong reaction isn’t something to push through.

The verdict: which of the best NMN supplements should you buy?

Our pick, and the one to buy if you take NMN daily: Eternal Elixir NMN 500mg. At $0.56 per 500 mg, it is the lowest-cost capsule in this comparison, the full 500 mg is in one capsule, and a bottle covers 90 days.

If published lot documents matter most: ProHealth NMN Pro 500, with branded Uthever NMN and a linked certificate of analysis, at $1.43 per 500 mg.

If the lowest cost per milligram matters most and you don’t mind scoops: Renue By Science NMN Pure Powder at about $0.27 per 500 mg.

If you want the top of the studied dose range in one product: Wonderfeel Youngr NMN, 900 mg per serving plus extras, at $1.63 per 500 mg of NMN.

If you are consolidating a stack: our NMN Advanced Longevity Complex replaces several bottles with one 30-serving bottle, at a higher cost per milligram of NMN.

If you want the lowest upfront price for NMN plus resveratrol: VitaSolutions NMN + Resveratrol at $35.00, with the caveat that you will need the physical bottle to work out servings.

Whichever you choose, convert to cost per 500 mg before comparing, and prefer documents over adjectives. The same habit works across longevity ingredients, from NMN to shilajit.

Frequently asked questions about NMN supplements

What is the best NMN supplement?

Our pick is Eternal Elixir NMN 500mg, because it puts 500 mg of NMN in one capsule, gives 90 servings per bottle, and at $0.56 per 500 mg it is the lowest-cost capsule in our comparison. If published lot documents matter more to you than cost, ProHealth NMN Pro 500 links a certificate of analysis, and if cost is everything, Renue By Science’s powder is cheaper per milligram.

Which NMN brand can you trust?

Trust should come from documents you can check, not from a brand name. Look for the NMN amount per capsule, the servings per container, a named raw material and a certificate of analysis for your lot. In this comparison, ProHealth and Renue By Science link lot test results on their product pages, and our NMN 500mg page states the evidence level and that NMN hasn’t been shown to extend human lifespan.

Which brand of NMN does David Sinclair recommend?

We found no brand recommendation from David Sinclair that we could verify. Be cautious with any product page or ad that implies his endorsement, and judge the product on its label and test documents instead.

What is the best form of NMN supplement to take?

For most people, a plain capsule such as Eternal Elixir NMN 500mg is the simplest: a fixed dose with nothing to measure. Powder costs less per milligram but needs measuring. Sublingual, liposomal and enteric formats are promoted for better absorption, but we found no published human trial comparing them with a plain capsule at the same dose.

Do NMN supplements actually work?

It depends on what you mean by work. Randomized trials show NMN raises blood NAD+ at 250 mg to 900 mg a day, and some found small improvements in walking distance, gait speed or muscle insulin sensitivity. No trial shows that NMN extends human lifespan or that its effects last years. Treat it as a well-tolerated compound with a measurable effect on a blood marker, not proven anti-aging.

What is the best NMN dosage per day?

Trials have used 250 mg to 900 mg a day, and the largest dose trial found the strongest results at 600 mg. Take any product as its own label directs. Our NMN 500mg label is one capsule (500 mg) per serving. Speak with your doctor before starting if you take prescription medicine.

What is the difference between NMN and NR?

Both are NAD+ precursors that sit at different points in the same pathway. NR (nicotinamide riboside) has been sold longer and has its own human research. NMN is one step closer to NAD+. Neither has been shown to be clearly better in people. See our nicotinamide riboside comparison for the NR side.

Is NMN better taken with resveratrol?

The idea is that NMN supplies an NAD+ precursor while resveratrol is linked to sirtuin activity, so they are often sold together. It is a plausible rationale, but no finished NMN and resveratrol product has been shown in a trial to beat NMN alone. If you want both, a combination can save money. If you only want NMN, you aren’t missing a proven benefit.

How long does NMN take to work?

In the 60-day dose trial, blood NAD was already significantly higher at the first check, day 30. Walking distance differences were also measurable by day 30. How you feel is another matter: many people notice nothing, and that is a normal result.

Is NMN safe to take long term?

Trials of up to about three months found NMN well tolerated at up to 900 mg a day, with no safety issues from adverse events or lab tests. Longer-term safety in people hasn’t been studied to the same standard. If you are pregnant or breastfeeding, take prescription medicine or manage a health condition, talk to your doctor first.

What is the difference between NMN and NAC?

They are unrelated compounds with similar acronyms. NMN is an NAD+ precursor. NAC (N-acetylcysteine) is a precursor to glutathione, the body’s main antioxidant inside cells. Different molecules, different pathways, different reasons to take them.
