These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
Full trial dose, public lab certificate, tested by independent lab.
Read the evidence (3 studies)Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.
This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

It delivers 250mg of NMN, inside the studied range of 250–900mg with grade B evidence (promising human data, not yet comprehensive). Transparency is a clear strength (score: 9.0), with third-party testing and a public lab certificate. At $1.63/day it's among the more expensive options in NAD+ booster.

Capsules are dosed at only 125 mg/capsule (250 mg/day at standard 2-cap serving), on the low end of the 250-1000 mg human research range. No separate 500 mg capsule SKU exists; higher doses require taking 4+ capsules or switching to the powder format. Priced high per mg ($48.95 for 60 caps = 15g total NMN) relative to category median.
