Our #1 pick
NMN Complete 1350mg

NMN Complete is the most comprehensive single formula in our range. It pairs a higher 750mg NMN dose with three complementary actives — TMG, pterostilbene and apigenin — in one daily serving. For people who want a full longevity stack without buying and timing four separate products, this is the clearest pick. Same UK manufacturing and ISO/IEC 17025 batch testing as every formula in the range.

Methodology

How we judged.

We evaluated every formula in the Vitality range on six neutral, verifiable criteria — the same lens covered in our how to choose an NMN supplement guide. No price weighting — pricing is evergreen and shown live on each product page. No efficacy claims — there are no authorised UK or EU specific health claims on NMN.

01
NMN dose per serving
The amount of nicotinamide mononucleotide in one daily serving, in milligrams, declared on the pouch and verified in the certificate of analysis. We do not penalise lower doses if they are paired with additional actives — the criterion is clarity and disclosure, not maximisation. See our NMN dosage guide for context on what published research has used.
02
Ingredient depth
How many active ingredients are in one daily serving. A single-active formula is not "worse" than a multi-active one — it serves a different goal. We rank for the use case: a comprehensive single formula scores higher when the comparison is "buy one product" rather than "build a stack."
03
Third-party batch testing
Every formula in our range is tested by an ISO/IEC 17025-accredited laboratory on every batch. A Certificate of Analysis is available on request for any batch — match the batch code on your pouch to the report. See our science page for the full lab and verification protocol.
04
Customer feedback
Verified review count and rating from the Vitality Supplements customer base. Two of our newest SKUs (Pure and TMG) don't yet have established review data — we flag this rather than invent it. Resveratrol leads on review volume; Complete and Resveratrol both sit at 4.9 average.
05
Manufacturing transparency
Made in the United Kingdom. Manufacturer address, batch tracking, ingredient sourcing and capsule shell (HPMC, vegan) all disclosed. Pouches carry the GTIN, batch code and best-before date — none of this is hidden or proprietary.
06
Regulatory framing
NMN is a permitted food supplement ingredient in the UK under the Food Supplements (England) Regulations 2003 and overseen by the FSA; not classified as a novel food. We make no medicinal or disease claims and no unauthorised health claims. Editorial framing is product, dose and testing — not outcome.
The Ranking

Five formulas, ranked.

A ranked list, not a hierarchy of quality — every formula passes the same testing and manufacturing standard. The order reflects the most-recommendable pick first, given the criteria above. If your goal is different, the "match by goal" section below will be more useful.

1Editor's pick

NMN Complete 1350mgThe most comprehensive single formula

Best for: one formula, full stack

Why it wins: Four ingredients in one capsule at a high 750mg NMN dose. It pairs NMN with TMG (a methyl donor used during NAD+ metabolism), pterostilbene (a methylated analogue of resveratrol) and apigenin (a botanical flavone). For most people who want a comprehensive longevity formula without buying four separate products, this is the clearest single pick.

Trade-offs to know: NMN dose is 750mg, not the 1000mg you'd get from Pure — if you want pure NMN at the highest dose specifically, Pure is the right call. The ingredient depth is the reason this ranks first, not the NMN milligrams alone.

2Runner-up

NMN + Trans-Resveratrol 1100mgThe classic pairing · most reviewed

Best for: first-time NMN, classic pairing

Why it ranks here: The two-ingredient pairing of NMN and Trans-Resveratrol is the combination most commonly studied alongside NMN, and this formula is the most-reviewed in our range — 1,876 verified UK reviews at 4.9 out of 5. If this is your first NMN supplement, the simpler ingredient profile, the classic pairing, and the deepest customer feedback are the case for this one.

Trade-offs: NMN dose is 500mg per serving — lower than Complete (750mg) or Pure (1000mg). Two ingredients, not four. If you want either a higher NMN dose or a fuller stack, look at Complete or Pure.

3Best single ingredient

NMN 1000mg PureHighest pure NMN dose in the range

Best for: NMN-only purists, custom stacks

Why it ranks here: The highest single-ingredient NMN dose in the range — 1000mg pure nicotinamide mononucleotide per serving, no blends. If you want NMN on its own — to control your own pairings, time it separately, or just keep the formula uncomplicated — this is the right one. See our NMN dosage guide for what published research has used.

Trade-offs: Newly launched, so verified customer review data isn't established yet. Same testing and manufacturing standard as every other formula in the range. No paired actives — if you want resveratrol, TMG, pterostilbene or apigenin, you'd add them separately or pick a combination formula.

4Focused pairing

NMN + TMG 750+750mgNMN with a methyl donor

Best for: NMN + methyl support, no extras

Why it ranks here: Equal 750mg doses of NMN and TMG in one daily serving — a focused two-ingredient formula for people who want NMN paired with a methyl donor but don't need pterostilbene or apigenin on top. Higher NMN dose than the Resveratrol pairing, simpler than Complete.

Trade-offs: Newly launched, so no established review count yet. If you want all the actives Complete carries (TMG plus pterostilbene plus apigenin) in one formula, pick Complete; this is for the focused TMG case.

5Reduced form

NMNH 500mgThe reduced form of NMN

Best for: experienced NMN users exploring the reduced form

Why it ranks here: NMNH is the reduced form of NMN — same NAD+ precursor family, distinct chemistry, different absorption profile, enters the salvage pathway differently. For people already familiar with NMN who want to explore the newer reduced form, it's a sensible second purchase.

Trade-offs: Not the first NMN supplement to try — the research base is younger than for standard NMN, and the form is different enough that starting here doesn't tell you much about how you'd respond to standard NMN. See the NMN vs NMNH guide for the full breakdown.

FAQs

Buying-decision questions.

Of the five formulas in our range, NMN Complete 1350mg is our editor's pick — the most comprehensive single formula, pairing 750mg NMN with TMG, pterostilbene and apigenin in one daily serving. It's rated 4.9 from 842 verified reviews. For a simpler two-ingredient option, NMN + Trans-Resveratrol is the most-reviewed (1,876 reviews) and the classic pairing. For pure NMN at the highest dose, NMN 1000mg Pure.
If this is your first NMN supplement, NMN + Trans-Resveratrol is a common starting point — two ingredients, the classic pairing, the deepest customer feedback. If you want the most comprehensive single formula and prefer one capsule over building a stack, Complete adds TMG, pterostilbene and apigenin on top of a higher NMN dose.
Pure has more NMN per serving (1000mg vs Complete's 750mg), but Complete includes three additional actives. The ranking reflects ingredient depth and the convenience of a single formula, not NMN dose alone. If you specifically want NMN on its own at the highest dose, Pure is the right pick.
Yes. NMN is a permitted food supplement ingredient in the United Kingdom, regulated under the Food Supplements (England) Regulations 2003 and overseen by the FSA. It is not classified as a novel food by the FSA, meaning it can be legally sold as a food supplement without novel food authorisation. There are no authorised UK or EU specific health claims on NMN, so we make no medicinal or disease claims.
Look for four things: a clearly stated NMN dose per serving (not hidden inside a proprietary blend), independent batch testing by an ISO/IEC 17025-accredited laboratory, a Certificate of Analysis available on request, and a registered UK manufacturer. Every Vitality formula meets all four. The CoA for any batch can be requested by emailing info@vitality-supplements.co.uk with the batch code from the pouch.
There is no single authorised dose for NMN, as no UK or EU health claims are authorised on the ingredient. Published human studies have used doses from approximately 250mg to 900mg per day. The Vitality range spans 500mg (Resveratrol pairing and NMNH) to 1000mg (Pure), with 750mg in Complete and NMN+TMG. See our NMN dosage guide for more.
TMG (trimethylglycine, betaine) is a methyl donor. NAD+ metabolism uses methyl groups, so some people pair a methyl donor with higher NMN doses. It's not strictly required — many take NMN without TMG. If you want the pairing in one capsule, Complete and NMN+TMG both include it.
NMNH is the reduced form of NMN. Both are NAD+ precursors, but NMNH has distinct chemistry and enters the salvage pathway differently. NMNH is newer and has less research behind it than standard NMN. Most first-time NMN users should start with a standard-NMN formula before exploring NMNH — see the NMN vs NMNH guide for the full breakdown.
Yes — every batch of every formula. Tested independently by an ISO/IEC 17025-accredited laboratory. A Certificate of Analysis is available on request for any batch — email info@vitality-supplements.co.uk with the batch code printed on your pouch. See our science page for the full testing protocol.
60-day satisfaction guarantee on first purchase. If the formula isn't right, contact us within 60 days for a refund — see the full returns & refunds policy. Free UK delivery applies to all orders.
