For picks on this page, we sort candidates by evidence score (human trial quality for common uses), then safety score, then prefer a lower hype gap when the first two tie. Pinned ingredients stay at the top so the page answers the headline before expanding context.
Numbers are not personalized risk scores and not brand QA. For the full rubric, read Methodology.
