Its page lists NMN and a vegetable cellulose capsule shell and nothing else.

This review covers NMN Bio's capsules as a UK buyer sees them on its own site. We read the product pages on 28 October 2026 and did not lab-test anything. We also sell a competing product, RGENR8 Pure NMN Pro, which is why it sits in the tables. NMN Bio's own pages are the source for every NMN Bio figure here.

NMN Bio NMN price in the UK, per capsule and per gram
NMN Bio's 500mg capsule comes in a 30-capsule bottle, which its page describes as 30 days in one bottle. The one-off price is £60.00. Subscriptions lower the bottle price as the delivery gap lengthens, down to £40.20 on the annual plan. It also lists a 250mg capsule at £34.00 one-off, but the page does not state how many capsules are in the bottle, so we cannot work out a price per gram for it.

Prices checked 28 October 2026 on each product page, in GBP, for UK delivery. NMN Bio figures are from its 500mg product page; the CSV in our UK NMN Price Index logged the same £60.00 one-off on 10 October 2026. Price per gram is the pack price divided by grams of NMN (30 capsules of 500mg is 15g; 90 capsules is 45g). Sums: £60.00 / 15 = £4.00, £49.80 / 15 = £3.32, £45.00 / 15 = £3.00, £42.60 / 15 = £2.84, £40.20 / 15 = £2.68, £24.95 / 15 = £1.66, £22.95 / 15 = £1.53, £34.99 / 45 = £0.78, £27.99 / 45 = £0.62. NMN Bio's page gives a dose of 1 or 2 capsules a day; the monthly column assumes one. Prices change with promotions, so check each page before you buy.

What is in NMN Bio's capsule, and what it says about testing
The product page lists NMN and a vegetable cellulose capsule shell, with no other ingredients. Its testing text says each batch is checked by an independent laboratory for NMN identity and purity, heavy metals and microbiological contaminants, and that a batch report is emailed after you order. The page offers a 30-day guarantee, and the site lists several stockists, Boots among them. We did not check any stockist's own price.
Whichever brand you buy, the same six checks work on any certificate:
- 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 is at least 99% pure and tests every batch with an independent accredited lab. Shop Pure NMN Pro.

Sums: £29.99 / 15 = £2.00, £59.99 / 30 = £2.00, £49.04 / 22.5 = £2.18. The DoNotAge capsule is 1,000mg, so one capsule is a 1,000mg dose and 500mg a day is half a capsule; the monthly figure is the price of 15g. Renue by Science LIPO NMN is a liposomal product with extra ingredients. Check each brand's page for its current price.
