At one 500mg capsule a day, six months of NMN is 180 capsules and a year is 360. On the RGENR8 3-month plan, six months costs £62.98 (35p a day) and a year costs £132.96 (37p a day), delivered free in the UK. If you take 1,000mg a day, or you are buying for two people, double the capsule count; the table below has every case worked out.
Capsules you need, at a glance
Pure NMN Pro has 500mg of NMN in each capsule, so you need one capsule a day for every 500mg you take. Most people in the human trials took between 250mg and 1,000mg a day (our NMN dosage per day guide has the full list), and one capsule a day is the usual routine.
| Daily amount | 3 months | 6 months | 12 months |
|---|---|---|---|
| 500mg a day (1 capsule) | 90 capsules | 180 capsules | 360 capsules |
| 1,000mg a day (2 capsules) | 180 capsules | 360 capsules | 720 capsules |
| Two people at 500mg each | 180 capsules | 360 capsules | 720 capsules |
Months are counted as 90, 180 and 360 days, so the numbers match whole 30-capsule bottles.
What 6 months and a year cost with RGENR8
There are four ways to buy, and the 3-month plan comes out lowest over any period. Every price includes free UK delivery.
| How you buy | 6 months (180 capsules) | Per day | 12 months (360 capsules) | Per day |
|---|---|---|---|---|
| 3-month plan, 90 capsules every 3 months £27.99 first delivery with WELCOME20, then £34.99 | £62.98 | 35p | £132.96 | 37p |
| 3-pack bought once (90 capsules, £34.99) | £69.98 | 39p | £139.96 | 39p |
| Monthly plan, 30 capsules a month £18.36 first month with WELCOME20, then £22.95 | £133.11 | 74p | £270.81 | 75p |
| Single bottle bought once (30 capsules, £24.95) | £149.70 | 83p | £299.40 | 83p |
RGENR8 prices on 4 November 2026 (also as pricing.json). Per day = total ÷ days, at one 500mg capsule a day. WELCOME20 applies to the first order of a plan; codes do not apply to the 3-pack bought once.
Over six months the 3-month plan works out at £0.70 a gram of NMN, and its first delivery is £0.62 a gram, the lowest first-order price per gram we have found for 500mg NMN capsule packs under 1,000 capsules in the UK NMN Price Index.
1,000mg a day, or two people
Both need 180 capsules every three months. With RGENR8 the lowest-cost way is one 3-month plan plus a 3-pack bought once each quarter:
| Period | Capsules | 3-month plan | 3-packs bought once | Total | Per capsule |
|---|---|---|---|---|---|
| 3 months | 180 | £27.99 | 1 x £34.99 | £62.98 | 35p |
| 6 months | 360 | £62.98 | 2 x £34.99 | £132.96 | 37p |
| 12 months | 720 | £132.96 | 4 x £34.99 | £272.92 | 38p |
So two people taking one capsule each pay about 38p per person per day over a year, close to the 37p one person pays on the plan alone. Someone taking 1,000mg a day pays about 76p a day for both capsules.
Why a plan beats buying a year up front
You pay £27.99 to start and at most £34.99 at a time after that, which is easier on the bank balance than £100 or more on day one. A fresh delivery arrives every quarter, so there are only ever three months of capsules in the cupboard. Keep them somewhere cool and dry, as our guide to storing NMN explains.
You can pause, switch or cancel the plan online whenever you like, and there is a 30-day money-back guarantee.
What is in each capsule
Each Pure NMN Pro capsule is 500mg of beta-NMN and nothing else: no fillers or binders, a vegan HPMC shell and at least 99% purity, made to GMP-equivalent standards and batch tested by an independent accredited lab. People take it to support cellular energy and healthy NAD+ levels as part of a daily routine; the label says it supports healthy cell function and may support overall vitality and well-being.

Common questions
How much does a 6-month supply of NMN cost in the UK?
At one 500mg capsule a day, six months is 180 capsules. On the RGENR8 3-month plan that is £62.98: £27.99 for the first 90 capsules with code WELCOME20, then £34.99 for the next 90. That works out at 35p a day, with free UK delivery.
How much does a year of NMN cost?
A year at 500mg a day is 360 capsules. On the RGENR8 3-month plan it costs £132.96 (£27.99, then three deliveries at £34.99), or about 37p a day. Buying the 3-pack four times costs £139.96, and twelve single bottles cost £299.40.
How many capsules do I need for 6 months at 1,000mg a day?
1,000mg a day is two 500mg capsules, so six months takes 360 capsules, the same as a year at 500mg. With RGENR8 that is £132.96 on the 3-month plan plus 3-packs, which is 37p for each 500mg capsule.
What is the cheapest way for two people to take NMN?
Two people at 500mg a day use 180 capsules every three months. The lowest-cost way with RGENR8 is one 3-month plan (£27.99 first, then £34.99) plus a 3-pack bought once each quarter (£34.99). A year for two costs £272.92, about 38p per person per day, delivered free.
Should I buy a whole year of NMN at once?
You don't need to. The 3-month plan sends 90 capsules every three months, so you never have more than a quarter's supply in the cupboard, you pay in small steps, and you can pause or cancel online any time.
Is NMN legal to buy in the UK?
NMN has no GB novel food authorisation yet. The application, RP-2116, is at risk assessment with the Food Standards Agency. Our guide to NMN and UK novel food law covers what that means for buyers.
Ready to start? Pick "3 bottles every 3 months" on the Pure NMN Pro page and your first 90 capsules are £27.99.
If you are pregnant, breastfeeding, taking medication or managing a health condition, check with your GP or pharmacist before taking any supplement.
