Evidence Codex is an educational reference, not medical advice. Many compounds listed are unapproved or have limited human evidence. Read the medical disclaimer.

About

Health knowledge should be free, and no one's word is final.

Evidence Codex started because the same misinformation keeps getting repeated online until it sounds true. So this is a plain reference: what a compound is, what the evidence actually says, and free tools to run your own numbers.

The one rule

Take everything with a grain of salt. This site included.

A big following, a confident voice, and telling you what you want to hear don't make someone right. Read the evidence badge on every claim, follow the sources, and double-check anything that matters for yourself. A compound can have solid evidence for one use and almost none for another, so the profiles keep those apart.

Evidence key

What the labels mean.

Badges summarize the type of support behind a claim. They are a starting point, not a verdict on whether a compound is appropriate for a person.

Approved labelUse, dose or safety information appears in an official product label or regulator-reviewed document.
Human clinical evidenceHuman trials, clinical studies or case data are available for the question being discussed.
Preclinical evidenceSupport comes mainly from cell, animal, mechanism or early translational research.
Safety warningRegulators, labels or clinical sources flag a meaningful risk or monitoring concern.
Limited or unverifiedClaims are common online but have thin, indirect or poorly documented support.
