Bevisning 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. Säkerhet 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.

Important to know
C15:0The healthiest cohorts get C15:0 from dairy fat — the supplement story assumes the molecule, not the milk matrix, is the active agent. That assumption is untested in human trials.
