BetterVits NMN Complex is a blend with 250mg of NMN per capsule, and it works out at £2.33 to £3.00 per gram of NMN bought one-off, or from £2.00 a gram on subscription (checked 24 October 2026). RGENR8 Pure NMN Pro is 500mg of NMN alone in each capsule, at £27.99 for 90 on a first 3-month order (£0.62 a gram, 31p a day), then £34.99 every 3 months (£0.78 a gram).
This review covers BetterVits' prices, label and terms as it publishes them. On 24 October 2026 we read its product page and nutrition label as a UK visitor; we did not lab-test the capsules. We sell a competing product, RGENR8 Pure NMN Pro, which is why both sit side by side in the tables. The brand also appears as Bettervits or Better Vits, and the product's full name is NMN Complex with Resveratrol and Quercetin.

Checked 24 October 2026 on each seller's own page, in GBP, with free UK delivery on every pack. Price per gram is the pack price divided by the grams of NMN in it: 15g in a 60-capsule BetterVits bottle and 45g in RGENR8's 90 capsules. It counts NMN only, so it leaves out BetterVits' resveratrol and quercetin. BetterVits lists the lower prices under "Subscribe & Save Up To 33%" (delivery every 30, 60 or 90 days), and its store runs a price-testing script, so other visitors may see different prices. We left out a 10% first-order newsletter offer because we have not seen how it applies; on the 3-bottle subscription it would make £81.00, or £1.80 a gram. The UK NMN Price Index records BetterVits' one-off prices (see our BetterVits price page).
What a year of 500mg NMN a day costs
A year of 500mg of NMN a day (360 days, 180g of NMN) costs £360.00 on BetterVits' 3-bottle subscription and £132.96 on RGENR8's 3-month plan, a gap of £227.04.
| Route | How the year adds up | Capsules | 12-month total | Per gram of NMN |
|---|---|---|---|---|
| BetterVits 6 bottles, one-off | 2 x £210.00 | 720 | £420.00 | £2.33 |
| BetterVits 3 bottles, subscription | 4 x £90.00 | 720 | £360.00 | £2.00 |
| RGENR8 3-month plan | £27.99 first order, then 3 x £34.99 | 360 | £132.96 | £0.74 |
Assumes today's prices hold for the year and the first-order code is used once. Delivery is free on both. BetterVits takes two capsules for each 500mg of NMN, so a year is 12 bottles.
BetterVits NMN Complex vs pure NMN: what the blend changes
The blend halves the NMN in each capsule. BetterVits' label lists 500mg of NMN, 250mg of resveratrol and 250mg of quercetin per 2-capsule serving, so each capsule carries 250mg of NMN alongside the other two.
Its ingredient list also names brown rice flour as a bulking agent and bamboo silica as an anti-caking agent, in an HPMC capsule shell. Both are ordinary, declared excipients, and our page on NMN with no fillers explains why capsule makers use them. RGENR8 Pure NMN Pro lists 500mg of beta-NMN in a vegan HPMC shell and nothing else.
Two practical things follow. You take two BetterVits capsules for 500mg of NMN, against one RGENR8 capsule. And the NMN dose is tied to the resveratrol and quercetin dose, so you cannot change one without the other. If you would rather have all three in one serving, the blend does that. To set each amount yourself, you can buy resveratrol separately and pair it with pure NMN; our NMN and resveratrol guide prices that route against the UK combination products.
BetterVits and RGENR8 side by side: specification and terms
Both are vegan capsules from UK brands with free delivery. Where they differ is what goes in the capsule and what a gram of NMN costs.

What BetterVits publishes about testing
We found no certificate of analysis on BetterVits' product page on 24 October 2026. The page shows a "3rd Party Tested" badge, along with "Vegan and Gluten-Free" and "Nutritionist Approved", but names no lab and publishes no batch results or purity figure.
To see what was tested and the results, ask BetterVits for the certificate for the batch you receive. With a blend, look for NMN content reported as its own result per capsule (250mg on this label), separate from the resveratrol and quercetin.
These six checks apply to any brand's 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 know 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.
BetterVits NMN at Boots
Boots sells BetterVits NMN Complex online. On 10 October 2026 we found the 60-capsule bottle on Boots' website at £45.00, the same as one bottle bought direct, listed without NMN amounts (BetterVits' own label puts it at £3.00 a gram). Boots blocked our check on 24 October 2026, so we have not reconfirmed that price. NMN at Boots and Holland & Barrett lists the other NMN products both chains carry.
Who BetterVits suits, and who RGENR8 suits
BetterVits suits buyers who want NMN, resveratrol and quercetin in one serving. It is also the one you can order from Boots.
RGENR8 suits buyers who want 500mg of NMN on its own, in one capsule a day, at a lower price per gram: £0.62 on the first 3-month order and £0.78 after, with free UK delivery and the certificate on request. That £0.62 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 BetterVits NMN any good?
We have not lab-tested it, so we cannot say how any capsule performs. Its label states 500mg of NMN per 2-capsule serving (250mg a capsule) with 250mg each of resveratrol and quercetin, and its product page shows a "3rd Party Tested" badge but no certificate or results. It costs £2.00 to £3.00 per gram of NMN. If price per gram of NMN matters most to you, RGENR8's 3-month plan is £0.62 a gram on a first order, then £0.78.
How much NMN is in BetterVits NMN Complex?
250mg per capsule. The label gives a serving of 2 capsules holding 500mg of NMN, 250mg of resveratrol and 250mg of quercetin, with 30 servings in a 60-capsule bottle. That is 15g of NMN per bottle.
How much does BetterVits NMN cost in the UK?
On 24 October 2026 BetterVits listed one 60-capsule bottle at £45.00, three at £120.00 and six at £210.00, which is £3.00, £2.67 and £2.33 per gram of NMN. Its subscribe-and-save prices were £40.00 for one bottle, £70.00 for two and £90.00 for three, the last of which is £2.00 a gram. Delivery is free.
Is BetterVits NMN sold at Boots?
Yes. On 10 October 2026 Boots' website listed BetterVits NMN Complex, 60 capsules, at £45.00, the same price as one bottle bought from BetterVits. Boots blocked our check on 24 October 2026, so we have not reconfirmed that price. NMN at Boots and Holland & Barrett lists the other NMN products both chains carry.
BetterVits NMN vs pure NMN: which is better value?
Per gram of NMN, RGENR8's pure NMN costs less: £0.62 a gram on a first 3-month order and £0.78 after, against £2.00 at BetterVits' lowest stated price. BetterVits' price also pays for 250mg each of resveratrol and quercetin per serving, so if you want both, compare it with pure NMN plus a separate resveratrol capsule, as our NMN and resveratrol guide does.
Is BetterVits legit?
On the public record we checked, yes. BetterVits is sold by BetterCo Ltd of 93 George Street, Edinburgh, and Companies House lists BETTERCO LTD at that address (company SC693954, active, incorporated 30 March 2021). Like every NMN product sold in Britain, BetterVits NMN Complex has no GB novel food authorisation yet; the application, RP-2116, is at risk assessment with the Food Standards Agency.
