DoNotAge NMN Review 2026: UK Brand, 1,000 mg Dose, Powder Pricing, and the Evidence Gap

What the Label Says

Pure NMN capsules contain 500 mg of Uthever β-nicotinamide mononucleotide per capsule in an HPMC vegetarian shell. The powder form contains the same NMN without a capsule shell. Both list 99.8% purity. The recommended serving is two capsules or two scoops daily, totaling 1,000 mg.

We took these details from the DoNotAge product page on October 17, 2026. The formula is as minimal as an NMN product can be: NMN and a capsule shell. No resveratrol, no BioPerine, no additional actives. That simplicity is the point. A buyer who wants plain NMN with nothing else gets exactly that.

The NMN raw material is Uthever, manufactured by Effepharm, the same branded ingredient used by Omre, ProHealth, and several other NMN brands we review. Uthever has its own stability and identity testing program, which means the starting material comes with a baseline level of documentation before the brand's own testing adds another layer.

The capsule uses hydroxypropyl methylcellulose (HPMC), a plant-based material that makes it suitable for vegans. There are no fillers, flow agents, or binding agents listed. That puts DoNotAge in the cleanest-label tier of NMN products.

The 1,000 mg Recommendation: Where It Sits Against the Trials

DoNotAge recommends 1,000 mg of NMN per day. Most published human trials used 250 to 500 mg. One dose-response study used 300, 600, and 900 mg, and a safety study tested 1,250 mg. The 1,000 mg dose has not been tested in a published clinical trial for efficacy outcomes.

This is the single most important thing to understand about DoNotAge's product recommendation. Most NMN brands suggest 500 mg per day, which matches the upper end of the most commonly tested range. DoNotAge suggests twice that. The suggestion is not reckless, but it is not backed by trial data at that exact dose.

Here is what the published trials actually used:

Study	Daily dose	Duration	Result
Yoshino et al., 2021	250 mg	10 weeks	Muscle insulin sensitivity improved
Okabe et al., 2022	250 mg	12 weeks	Safe; NAD+ increased
Yi et al., 2023	300, 600, 900 mg	60 days	NAD+ rose dose-dependently; six-minute walk improved
Liao et al., 2021	300, 600, 1,200 mg	6 weeks	Ventilatory thresholds improved at 600 and 1,200 mg; VO2max unchanged
Fukamizu et al., 2022	up to 1,250 mg	4 weeks	No serious adverse events at any dose

The closest study to DoNotAge's recommendation is Yi et al., which tested 900 mg and found dose-dependent NAD+ increases and improved walking distance. Liao et al. used 1,200 mg in runners and saw improved ventilatory thresholds at that dose, though not at 300 mg. Fukamizu went up to 1,250 mg and found no safety problems over four weeks.

So 1,000 mg appears safe in the short term. Whether it produces meaningfully better outcomes than 500 mg is an open question. The Yi study suggests higher doses raise NAD+ more, but no trial has compared 500 mg and 1,000 mg head-to-head for a health outcome. A buyer who follows DoNotAge's recommendation will go through two capsules a day and a $80 bottle in 30 days instead of 60, which doubles the monthly cost. Our NMN dosage guide covers the dose question in detail.

The Powder Advantage

DoNotAge's NMN powder lets buyers set their own dose, which no capsule product can match. It also costs less per gram than capsules because there is no encapsulation step. The trade-off is measuring accuracy and taste.

NMN powder dissolves in water and can be taken sublingually (held under the tongue). A 2026 crossover study in 14 healthy men found that sublingual and swallowed NMN produced the same blood NAD+ levels over 60 minutes (Wakabayashi et al., 2026). So the sublingual route does not appear to offer an absorption advantage, but the powder format still has practical value: you can take 250 mg, 500 mg, or any amount in between without splitting capsules.

DoNotAge users on Trustpilot describe the taste as "lemony" and "sweet and smooth." The cost per 500 mg from the 100-gram powder container is roughly $0.40, making it one of the cheapest NMN servings available from a brand that publishes testing data. For buyers who prioritize cost efficiency above convenience, powder is the rational format.

The downside is measurement. A scoop is imprecise compared to a capsule, and small weighing errors compound over weeks. If consistent daily dosing matters to you, capsules or a milligram scale solve that problem. Our NMN formats guide compares powder, capsules, and sublingual options across brands.

NMN from DoNotAge vs NR from Tru Niagen: Different Precursors, Similar NAD+ Outcome

DoNotAge's NMN and Tru Niagen's NR (nicotinamide riboside) both raise blood NAD+. A 2026 head-to-head trial found comparable NAD+ increases for NMN and NR over 14 days, while plain nicotinamide did not. The precursor choice is less important than dose, cost, and documentation.

DoNotAge, like most NMN brands, frames NMN as the preferred NAD+ precursor. The company's blog content positions NMN as more efficient because it is one enzymatic step closer to NAD+ than NR. That is biochemically accurate in a test tube. In people, a 2026 trial comparing the two found the same result: both raised blood NAD+ by comparable amounts (Christen et al., 2026).

NR has a longer clinical publication history, partly because ChromaDex, the company behind Tru Niagen's NIAGEN ingredient, has funded more trials than any single NMN supplier. NMN's trial base is growing and now includes dose-response data. For a buyer choosing between the two precursors, price per serving and testing documentation are more practical differentiators than the precursor itself. Our NMN vs NR guide covers this comparison without a commercial stake in the answer.

Price Comparison: Where DoNotAge Sits

DoNotAge is among the cheapest NMN products per gram from a brand that publishes certificates of analysis. In capsule form, cost per 500 mg is roughly $1.33. In powder form, it drops to about $0.40. Both are below the market average.

Product	NMN per serving	Format	Cost per 500 mg NMN
DoNotAge Pure NMN (powder, 100g)	500 mg (one scoop)	Powder	about $0.40
DoNotAge Pure NMN (capsules, 60ct)	500 mg (one capsule)	Capsule	about $1.33
Nutricost NMN	500 mg	Capsule	about $0.57
YourHealthier NMN (our product)	500 mg	Capsule	about $1.67
ProHealth NMN Pro 500	500 mg	Capsule	about $1.50
Omre NMN + Resveratrol	500 mg NMN + 500 mg resveratrol	Capsule	about $2.30

The powder pricing makes DoNotAge one of the most cost-effective options in the NMN market. The capsule pricing is competitive but not the cheapest; Nutricost undercuts it significantly. The comparison is fair only among brands that publish some form of testing documentation. Untested NMN from marketplace sellers can be cheaper still, but the purity risk makes the saving questionable.

DoNotAge also offers an annual subscription model, where buyers pay upfront for a year's supply at a discounted rate. That locks in a lower price but also locks in a commitment. Check the current terms and cancellation policy before subscribing. Reviews of the other products in this table are in our Omre review, Nutricost review, and ProHealth review.

Testing and Documentation

DoNotAge states that its NMN is independently tested by Eurofins Scientific, a large European laboratory network with ISO 17025 accreditation. The brand displays COA images on its product page and says certificates are available on request by email.

Eurofins is a credible testing partner. It is one of the largest analytical laboratory networks in the world, with over 900 laboratories in 60 countries. Having an identifiable, accredited lab named publicly is a transparency step that many NMN brands do not take.

What we could not confirm from the product page alone is exactly what the COA covers. A useful certificate should include β-NMN identity confirmation, a numeric purity assay, and heavy metal results for lead, arsenic, cadmium, and mercury. Some brands publish COAs that test only for purity and skip contaminants. Before buying, email DoNotAge for the certificate matching your lot and check what analytes it reports. Our NMN COA checklist explains what to look for line by line.

One Trustpilot reviewer noted that they asked for a certificate and received it by email promptly, which is a good sign for customer-facing documentation. The brand's product page shows an image of a COA, but a page image is not the same as a downloadable, lot-specific document. Ask for the actual file.

The "Health Research Organization" Positioning

DoNotAge describes itself as a health research organization rather than a supplement company. It says it reinvests profits into longevity research, funds PhD students, and runs clinical trials. That framing is unusual in the supplement industry and worth examining for what it means in practice.

The company's advisory board includes Vera Gorbunova, a professor of biological sciences at the University of Rochester who has published extensively on DNA repair, telomeres, and longevity across species. Having a researcher of that caliber on an advisory board is a real credential. It does not mean the advisory board designed the NMN capsule, which is a straightforward single-ingredient product, but it does mean the company has access to scientific guidance that most supplement startups do not.

DoNotAge says it funds research at institutions including the University of Singapore. The company has also supported PhD students working on longevity-related projects, including research on quercetin. These are modest but tangible contributions to the field.

What the "research organization" framing does not change is the regulatory reality. DoNotAge sells dietary supplements. Its products are not drugs, are not FDA-approved, and make no disease claims. The research funding is genuine corporate social responsibility, but a buyer is still purchasing a supplement, not a research output. The NMN in the capsule is the same Uthever powder available from multiple other brands.

What DoNotAge Customers Say: Trustpilot Themes

DoNotAge holds a 4.3 out of 5 on Trustpilot with over 500 reviews. Positive reviews mention energy improvements, clean ingredients, and responsive customer service. Negative reviews cite high pricing on multi-product orders, issues with the sachet product, and shipping delays to some regions.

The most common positive theme is subjective energy improvement after a few weeks of use. Several reviewers mention noticing less afternoon fatigue. These are anecdotal reports, not controlled observations, but they are consistent with what NMN trial participants have reported in open-label studies.

The most common negative theme is value. One reviewer described their chemist fiancé finding the same NMN active ingredient for "about a seventh of the price." That is plausible: bulk NMN powder from unbranded sources can be much cheaper, though it often comes without testing documentation. Another reviewer described the 15-in-1 sachet's monthly cost of approximately $200 as too high for what it delivers. The single-ingredient NMN products attract fewer complaints on pricing.

Customer service appears responsive based on review replies. The brand actively responds to negative reviews on Trustpilot, which is a positive sign. It does not resolve every complaint (the sweetener issue in the sachet product was flagged but not addressed to the reviewer's satisfaction), but the engagement is above the supplement industry average.

A 2026 review noted that NAD+ precursor supplementation showed biological activity but that effectiveness for anti-aging and wellness outcomes remained inconclusive across 113 studies (Palmer et al., 2021). Trustpilot testimonials do not change that evidence picture, but they do reflect a customer base that is largely satisfied with the product and the company.

The 15-in-1 Sachet and Product Line Expansion

In 2026, DoNotAge launched a daily sachet containing 15 longevity ingredients. Early reviews on Trustpilot were mixed: some users praised the convenience, while others complained about undisclosed sweeteners (stevia and erythritol) and the high monthly cost of approximately $200.

The sachet bundles NMN, resveratrol, TMG, spermidine, and other ingredients into a single daily drink mix. For someone already taking five or six separate supplements, consolidation has obvious appeal. The concern is transparency. At least one reviewer reported discovering stevia and erythritol in the product only after purchasing, and customer service could not resolve the issue to their satisfaction.

Undisclosed ingredients in a supplement product are a quality control flag. If a brand's selling point is purity and transparency, every ingredient should be on the label before the customer buys. Whether this was a labeling delay or an oversight, it undermines the trust the brand works to build with its testing documentation.

We focus this review on the Pure NMN product, which has a clean label and a long track record. The sachet is a different product with different considerations.

Safety at 500 mg and 1,000 mg

NMN has been tested in humans at doses up to 1,250 mg daily for four weeks with no significant adverse events. A 2026 meta-analysis found oral NMN generally well tolerated. Buyers who follow DoNotAge's 1,000 mg recommendation are within the tested safety range, though long-term data at that dose is limited.

The safety data for NMN up to 500 mg is reasonably strong, with multiple trials lasting 8 to 12 weeks. Above 500 mg, the data is thinner. Fukamizu's study at 1,250 mg lasted only four weeks. Liao's study at 1,200 mg lasted six weeks. Neither found safety problems, but neither ran long enough to rule out issues that might appear after months of daily use (Yang et al., 2026).

A 2026 review of 113 NAD-related studies noted clear biological activity from NMN supplementation but described the overall evidence for health outcomes as inconclusive (Gallagher et al., 2026). That applies regardless of dose.

NMN is lawful as a US dietary supplement following the FDA's September 2025 reversal. In the UK, where DoNotAge is based, NMN's regulatory status as a food supplement has been less clear. Buyers outside the US should check their country's current rules. Our NMN FDA status page covers the US timeline, and our NMN side effects guide lists commonly reported effects.

Who DoNotAge Pure NMN Fits

DoNotAge fits buyers who want the lowest cost per gram of documented NMN, especially in powder form. It also suits people who want to dose flexibly. It is less suited to buyers who want a capsule-only product at the lowest capsule price, where Nutricost wins.

The cost-conscious powder user. If you are comfortable measuring your own dose and price is your top priority, DoNotAge powder at roughly $0.40 per 500 mg is hard to beat among brands that publish testing data.

The flexible doser. Someone who wants to try 250 mg for a month, then 500 mg, then 750 mg without buying different products can do that with powder. No capsule product offers that range.

The high-dose user. If you have decided, based on your own reading or a clinician's advice, to take 1,000 mg or more daily, DoNotAge's pricing and recommended serving align with that goal. Just know the evidence base is thinner at that dose than at 250 to 500 mg.

The capsule-only buyer on a budget. DoNotAge capsules at $1.33 per 500 mg are not the cheapest capsule option. Nutricost is less than half that price. If capsule convenience matters and you want the lowest possible cost, Nutricost is the more efficient choice.

The buyer who wants extras. DoNotAge sells plain NMN. If you want resveratrol, TMG, or other ingredients combined in the same capsule, look at Omre (NMN + resveratrol) or Wonderfeel (NMN + four additional actives). Our best NMN supplements guide compares all of them.

Our Verdict on DoNotAge

Solid NMN at a competitive price, especially the powder. The 1,000 mg recommendation overreaches the evidence, but the product itself is clean.

Buy the powder if cost matters. Take 500 mg daily unless your own doctor says otherwise. Ask for a lot-specific COA before your first order. The Eurofins testing and Uthever sourcing are legitimate quality signals in a market full of unverified claims.

What We Did Not Review

We did not test the product, review a lot-specific COA, or assess DoNotAge's other supplements (resveratrol, TMG, spermidine, SIRT6Activator, the 15-in-1 sachet). This review covers only the Pure NMN capsule and powder from what the brand publishes online, current through October 2026.

DoNotAge sells over a dozen products, and we focused on the flagship NMN because that is what buyers most often compare against single-ingredient NMN competitors. A COA review for a specific lot would strengthen this analysis; we plan to request one in a future update.

YourHealthier sells an NMN product, listed as ours in the price table above. DoNotAge was not contacted for comment and did not review this article.

DoNotAge vs Other NMN Brands: Format and Approach

DoNotAge competes in two lanes: against UK/European NMN brands on geography and trust, and against US budget brands on price. Its unique combination of powder format, published Eurofins testing, and aggressive 1,000 mg dosing sets it apart from the capsule-dominated market.

Feature	DoNotAge	ProHealth NMN Pro	Nutricost NMN
Headquarters	Derby, UK	Orlando, FL	Vineyard, UT
NMN per serving	500 mg (recommends 1,000 mg)	500 mg	500 mg
Powder option	Yes	No (capsules only in 500 mg line)	No
Named testing lab	Eurofins Scientific	Yes (NSF-related)	Third-party tested (lab unnamed on page)
Cost per 500 mg (capsule)	about $1.33	about $1.50	about $0.57
Advisory board with published researchers	Yes (Vera Gorbunova)	No named board	No named board

Each brand wins on a different axis. DoNotAge wins on powder pricing and advisory credentials. ProHealth wins on longevity in the market and documentation depth. Nutricost wins on capsule price. No single product is best for everyone; the decision depends on whether you prioritize cost, format, or documentation depth. Our individual reviews cover each in detail: ProHealth, Nutricost, Force Factor, and Micro Ingredients.

DoNotAge Pure NMN FAQ

Common questions about the product, dose, and company, based on the product page and the research above.

How much NMN is in DoNotAge Pure NMN?

500 mg per capsule or per scoop of powder. The brand recommends two servings daily (1,000 mg total). Most competing brands recommend one serving (500 mg).

Is DoNotAge NMN third-party tested?

Yes. The brand names Eurofins Scientific as its independent testing lab and displays a COA image on its product page. Ask for the full, lot-specific document by email before buying.

Is 1,000 mg of NMN safe?

A four-week safety study tested up to 1,250 mg daily with no significant adverse events (Fukamizu et al., 2022). Long-term data at 1,000 mg is limited. Talk to a doctor before doubling the dose most trials used.

Where is DoNotAge based?

Derby, United Kingdom. Founded in 2019 by Alan Graves. The US is by a wide margin its largest market.

Is DoNotAge NMN cheaper than capsules from other brands?

In powder form, yes. At roughly $0.40 per 500 mg from the 100g container, it undercuts most capsule products. In capsule form ($1.33 per 500 mg), it is mid-range. Nutricost capsules are cheaper.

Does DoNotAge use Uthever NMN?

Yes. The product page lists "Uthever β-nicotinamide mononucleotide" as the active ingredient. Uthever is manufactured by Effepharm and used by multiple NMN brands.

Should I take the powder or capsules?

Powder is cheaper and lets you adjust your dose. Capsules are more convenient and more precise. A 2026 study found sublingual NMN (the powder route) produced the same blood NAD+ as swallowed NMN (Wakabayashi et al., 2026), so absorption is not a deciding factor.

Who is on DoNotAge's advisory board?

The company lists Professor Vera Gorbunova (biological sciences, University of Rochester), Dr. Maher Madanat (medical doctor), and Nick Engerer (health technology). Gorbunova's published research on aging biology is the most notable credential.

Where can I compare other NMN products?
