How we review products

The evidence, transparency and value criteria behind the Nutrametric Score.

We evaluate five areas: formula transparency, fit between claims and published evidence, manufacturer and checkout transparency, price and guarantee value, and the severity of unresolved red flags.

Scores are editorial judgments, not customer ratings or certifications. We record what we could verify, identify what remains unknown and lower confidence when doses, ownership or refund terms cannot be confirmed. We do not imply hands-on or laboratory testing unless it actually occurred.
