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.

Redaktionellt notes

Root-only KSM-66 at the standard 300mg clinical dose used across most branded-KSM-66 trials, sold alongside Shoden as an alternative ashwagandha form; $19.99/90ct is a very competitive price point ($0.22/day).
