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.

69 resources · 209 references · updated Aug 17, 2026

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.

The app

There's also an app

Manasource turns this library into a daily practice — log meals, movement, and sleep against the same evidence you can read here. The library stays free and open either way.

How to read the signals

Score and freshness are visible in every list row, so you can judge an entry before opening it — the score rates how well the evidence supports it. Open a resource to inspect dates, associations, references, and claims.

Source contract

Content syncs from the library's canonical source. Everything here traces back to a versioned source file — no hand-edits, no drift.
