Editorial foundation

A transparent way to read complex information

Our goal is useful understanding, not persuasion. Every page states its scope and points readers toward stronger sources.

Source hierarchy

We prioritize systematic reviews, government and public-health agencies, regulatory labels, and primary research. News and secondary commentary are clearly labeled.

Evidence limits

A lack of evidence is not evidence of absence. We distinguish established findings, early research, animal studies, and unresolved questions.

Corrections and review

Readers can report a factual concern with a page reference and a stronger source. Corrections are dated and linked from the relevant page.

If there may be a medical emergency

Contact local emergency services or a poison-control center immediately. Do not rely on an educational website for diagnosis or treatment. If you are in the United States, Poison Control is available at poison.org or 1-800-222-1222.
