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.

Research behind this product

The studies that established the trial dose and evidence grade for each active ingredient in this product. Click through to read the original paper.

Important to know
Sulforaphane'Broccoli extract' without myrosinase = minimal sulforaphane. Insist on 'active sulforaphane' or 'with myrosinase'.

Redaktionellt notes

Derived from broccoli seed extract (not fresh broccoli sprout extract), pre-activated during processing rather than requiring myrosinase reaction in the gut. 20mg/day is a modest but plausible dose; frequently unavailable/backordered.
