Is NMN Legal to Buy in the UK?

Yes — NMN is legal to purchase and consume as a food supplement in the UK. The Food Standards Agency regulates supplement sale under retained EU food law (post-Brexit). NMN has no authorised UK health claims on the GB Nutrition and Health Claims Register, so marketing copy must describe NMN factually rather than asserting specific health benefits. Our product copy follows this framework: we describe what published research has examined, not what NMN does for you.

Buying NMN Safely — A Checklist

1. Buy from a UK-registered company. Look for a Companies House number and a UK address.
2. Verify independent testing. Ask for the Certificate of Analysis. A credible brand will share it on request.
3. Check the isomer. The label should specify β-NMN, not just "NMN".
4. Check the dose. 500mg/day is the most-studied dose; under 200mg is likely underdosed; over 1,000mg has no incremental published evidence.
5. Check who's behind the brand. A practising clinician with verifiable credentials is more trustworthy than an unnamed founder or an Instagram influencer.
6. Compare price-per-month, not headline price. Some brands sell smaller quantities at a lower headline price for a much higher monthly cost.
