The library
What the evidence actually supports.
Food, supplements, and exercise — measured effects, ranked by the strength of the research behind them. Free and open, no account needed.
- Scored
- Every entry carries a 0–10 evidence score earned from the strength of published human research. Nothing ranks because it is trending.
- Sourced
- References live on the entry itself. Open one to inspect the claims, associations, and studies behind the score.
- Dated
- A last-reviewed date shows how fresh the evidence is. Stale is not wrong, just not yet re-checked.
Rated highest by readers
Ordered by how readers here have voted. The 0–10 evidence score on each entry is a separate measure and does not move with the votes.
Browse by section
Every resource lives in one section, with the same score and freshness signals throughout.
