Method
Every figure here comes from the UK NMN Price Index. We read each product page on 24 October 2026, logged out, as a UK visitor, and used standard non-sale prices. Price per gram is the price divided by the grams of NMN in the pack. The best stated deal per gram applies the subscription saving or first-order offer each product page states (the largest saving where there are several plans), including a first-order code shown publicly on the site, such as RGENR8's WELCOME20; codes a brand does not publish, such as newsletter sign-up codes, are left out. Ranks compare all 106 products with a price per gram, and equal figures (to the penny) share a rank. Testing, certificate and origin details are reported as each brand states them; we did not verify anyone's certificates. Our own product follows the same rules. The full method covers inclusion rules and caveats. If a figure is wrong, email support@rgenr8.com with a link to the product page.
