Our top pick is NMN Complete 1350mg — a four-ingredient stack of 750mg NMN with TMG, Pterostilbene and Apigenin, ISO/IEC 17025 batch tested and made in the UK. It's the most complete single-dose formula in our range and replaces stacking several products. For pure NMN at the lowest cost per day choose NMN 1000mg Pure; for the classic pairing choose NMN + Trans-Resveratrol 1100mg; for added methyl support choose NMN+TMG. Always compare price per serving, not price per bottle.
The best NMN supplement we make — and the one we'd point most people to first. A high 750mg NMN dose combined with three complementary actives in a single daily serving, so it does the job of an entire stack on its own. ISO/IEC 17025 batch tested and UK manufactured.
NMN Complete is our all-round pick. If your need is narrower, these are the ones to reach for — all ISO/IEC 17025 tested and UK made.
Pure NMN at a 1000mg serving and the lowest price per serving in the range. For people who want straight NMN and care most about cost per day.
Our most-reviewed product (4.9★, 1,876 reviews) — NMN with Trans-Resveratrol, the most commonly studied pairing, in one capsule.
Equal 750mg doses of NMN and TMG (trimethylglycine) in one serving, for people who specifically want a methyl donor alongside their NMN.
Most NMN listings hide the numbers that matter. Run any product — ours included — through this before you buy.
We rank on five evidence-based, verifiable criteria: NMN dose in mg, third-party testing standard, country of manufacture, formulation fit, and price per serving. We don't score on marketing claims, and we work out price per serving so a bigger tub can't masquerade as better value.
Look for the NMN dose stated in mg and a stated purity. "Proprietary blend" or per-bottle-only labelling is a red flag — you can't compare what you can't see.
Independent accredited lab testing on every batch — identity, potency, heavy metals, microbials and allergens — with a Certificate of Analysis on request.
Made in a UK facility to GMP standards means traceable sourcing, UK consumer protections and faster shipping than an unverified import.
A bigger tub isn't automatically better value. Divide price by servings to get cost per day — the only number that matters. We show how to work it out below.
Pure NMN, or NMN paired with complementary compounds? Resveratrol is the most-studied pairing; TMG adds a methyl donor. Match the formula to what you want.
Full ingredient and dose disclosure, capsule counts and a clear nutrition panel. Vegan HPMC capsules, free from gluten, dairy, soy and GMO is a bonus.
Verifiable reviews, a real UK business and a returns policy. Vitality carries a 4.9★ rating and a 60-day satisfaction guarantee on first purchase.

Tub price tells you almost nothing. The number that matters is cost per day — and that depends on dose and servings as much as headline price. Here's how to compare any NMN supplement fairly:
Current pricing for every product is shown live on its page — for pure-NMN cost efficiency, NMN 1000mg Pure is our best-value pick; for the most actives in one serving, NMN Complete.

NMN is a direct precursor to NAD+, a coenzyme central to cellular energy metabolism whose levels decline with age. Human trials published since have studied oral NMN supplementation and its effect on blood NAD+ levels. In one randomised study, Yamane et al., Endocrine Journal (2023) reported a rise in NAD+ concentration over 12 weeks of supplementation versus placebo. We dose our formulas in line with published research and verify every batch by accredited testing.
