DoNotAge NMN costs £2.00 to £2.67 a gram in the UK at the one-off prices we found, and £1.91 a gram on its best stated deal: 60 capsules of 500mg for £57.15 on Healf's 10% subscription, checked 24 October 2026. RGENR8's 3-month plan is £27.99 for 90 single-ingredient 500mg capsules on a first order (31p a day, £0.62 a gram), which is under a third of DoNotAge's best price per gram.
This review covers DoNotAge's NMN capsules as a UK buyer can get them today. The brand is also written Do Not Age. Its own site showed a holding page on 24 October 2026 while it relaunched, so the prices here come from the two UK retailers listing the capsules that day, Healf and TRL Nutrition. We read both listings as a UK visitor. We did not lab-test the capsules. We also sell a competing product, RGENR8 Pure NMN Pro, which is why both appear in the tables.

DoNotAge NMN price in the UK, per capsule and per gram
DoNotAge's lowest price per gram on 24 October 2026 was £1.91, for the 60-capsule pack on Healf's subscription. One-off, it ran from £2.00 a gram (60 capsules at TRL Nutrition, shown as unavailable that day) to £2.67 (30 capsules at TRL Nutrition).
| Product | NMN per capsule | Capsules | Price shown | Per capsule | Per gram | Best stated deal | Per gram on deal |
|---|---|---|---|---|---|---|---|
| DoNotAge 60 capsules, at Healf | 500mg | 60 | £63.50 | £1.06 | £2.12 | £57.15 (10% subscription) | £1.91 |
| DoNotAge 60 capsules, at TRL Nutrition | 500mg | 60 | £59.99 (shown as unavailable) | £1.00 | £2.00 | None shown | £2.00 |
| DoNotAge 30 capsules, at TRL Nutrition | 500mg | 30 | £39.99 | £1.33 | £2.67 | None shown | £2.67 |
| RGENR8 3-month plan | 500mg | 90 | £34.99 every 3 months | £0.39 | £0.78 | £27.99 first order with WELCOME20 | £0.62 |
Checked 24 October 2026 on each listing, in GBP, for UK delivery. Price per gram is the pack price divided by the grams of NMN in the pack. 60 capsules of 500mg hold 30g, 30 capsules hold 15g and RGENR8's 90 hold 45g, so the sums are £63.50 / 30 = £2.12, £57.15 / 30 = £1.91, £59.99 / 30 = £2.00, £39.99 / 15 = £2.67, £34.99 / 45 = £0.78 and £27.99 / 45 = £0.62. Healf states 500mg per capsule; TRL Nutrition states 1,000mg per two-capsule serving, which is the same 500mg a capsule. TRL Nutrition shows its packs as reduced from £68.00 (60) and £49.99 (30). Best stated deal is the lowest price per gram a listing states after a subscription saving or a public first-order code. Healf also shows a buy 3, get 1 free offer across brands, opted into at the basket; we left it out because it depends on what else is in the basket, but four DoNotAge packs for the price of three would be £190.50 for 120g, or £1.59 a gram, still above RGENR8's £0.62. Our UK NMN Price Index logged the Healf pack at £64.00 on 10 October 2026; see our DoNotAge price page, and what every UK NMN product costs per gram for the wider market.
Per 500mg capsule, DoNotAge is 95p on the Healf subscription and £1.06 one-off. RGENR8's 3-month plan is 31p on the first order and 39p after. DoNotAge suggests two capsules a day (1,000mg), so a 60-capsule pack lasts 30 days and costs £1.91 a day on the subscription.
What a year at 500mg a day costs
A year of 500mg a day (360 capsules, 180g of NMN) costs £342.90 on DoNotAge's Healf subscription and £132.96 on RGENR8's 3-month plan, a gap of £209.94.
| Route | How the year adds up | 12-month total | Per gram |
|---|---|---|---|
| DoNotAge 60 at Healf, one-off | 6 x £63.50 | £381.00 | £2.12 |
| DoNotAge 60 at Healf, 10% subscription | 6 x £57.15 | £342.90 | £1.91 |
| RGENR8 3-month plan | £27.99 first order, then 3 x £34.99 | £132.96 | £0.74 |
Both routes use 500mg a day so the grams match. At DoNotAge's suggested two capsules a day, its totals double. Assumes today's prices hold for the year and the first-order code is used once. RGENR8 delivers free in the UK.

What DoNotAge's testing documents show
The two listings we read state testing but do not link a certificate of analysis or name a lab. Healf's listing says every batch is third-party tested to 99%+ purity and names the ingredient as Uthever, a branded form of NMN. TRL Nutrition's listing has no testing statement in its text. DoNotAge's own site was on a holding page on 24 October 2026, so we could not check whether it publishes batch certificates there.
If you buy DoNotAge or any other NMN, these six checks work on any certificate, ours included:
- The lab is named, and you can look up its accreditation.
- The batch number matches the one printed on your bottle.
- The test date is recent.
- The sample is finished capsules (some certificates cover the raw powder).
- You can see which results sit inside the lab's accredited scope.
- NMN content and purity are measured, with the method named (HPLC is the usual one).
Our NMN purity checklist goes through each one. RGENR8 tests every batch with an independent accredited lab and sends the certificate of analysis on request.
What buyers say: public review counts
DoNotAge.org had 566 reviews on Trustpilot on 24 October 2026, with a TrustScore of 3.9 out of 5, on a profile the company claimed in April 2020. The Healf listing for the capsules showed 16 reviews averaging 4.6 out of 5.
We give counts only and do not quote individual reviews. Trustpilot is a separate site, and the Healf figures are the retailer's own.
Who DoNotAge suits, and who RGENR8 suits
DoNotAge suits buyers who want a named NMN ingredient (Uthever), a two-capsule 1,000mg serving, or the option of adding it to a Healf basket alongside other brands. It has also had a public Trustpilot profile since 2020.
RGENR8 suits buyers after single-ingredient 500mg capsules at a lower price per gram: £0.62 on the first 3-month order and £0.78 after, with free UK delivery, the certificate on request and a 14-day money-back guarantee on unopened bottles. That £27.99 first order is the lowest first-order price per gram for 500mg capsule packs under 1,000 capsules in our UK NMN Price Index.

Common questions
Is DoNotAge NMN worth it?
We have not lab-tested it, so we cannot say how any capsule performs. Its capsules hold 500mg of Uthever NMN each, and Healf's listing says every batch is third-party tested to 99%+ purity. On price, its best stated UK deal on 24 October 2026 was £1.91 a gram (60 capsules for £57.15 on Healf's subscription). If price per gram matters most, RGENR8's 3-month plan is £0.62 a gram on a first order and £0.78 after, for the same 500mg per capsule.
How much is DoNotAge NMN in the UK?
On 24 October 2026, 60 capsules of DoNotAge NMN (500mg each) were £63.50 at Healf, or £57.15 on its 10% subscription, which is £2.12 and £1.91 a gram. TRL Nutrition listed 30 capsules at £39.99 (£2.67 a gram) and 60 at £59.99 (£2.00 a gram), with the 60-capsule pack shown as unavailable.
Is DoNotAge legit?
Yes, on the public record we checked. DoNotAge.org has a Trustpilot profile it claimed in April 2020, with 566 reviews and a TrustScore of 3.9 on 24 October 2026, and UK retailers including Healf stock its capsules. Like every NMN brand sold in Britain, it sells a product with no GB novel food authorisation yet; the application, RP-2116, is at risk assessment with the Food Standards Agency.
What is a good DoNotAge alternative in the UK?
For single-ingredient 500mg capsules at a lower price per gram, RGENR8 Pure NMN Pro is £27.99 for 90 capsules on a first 3-month order (£0.62 a gram), then £34.99 every 3 months (£0.78 a gram). Our DoNotAge alternatives page ranks the eight closest products from other UK brands by price per gram.
How much NMN is in a DoNotAge capsule?
500mg. Healf's listing says each capsule delivers 500mg of NMN and suggests two capsules a day, so a 60-capsule pack lasts 30 days at 1,000mg a day. RGENR8 Pure NMN Pro is also 500mg a capsule, taken as one a day, so its 90 capsules last three months.
