How we work
No fluff, no fearmongering.
Evidence-cited
Every claim in a health article is backed by a citation — typically peer-reviewed research or a primary source. We name what we don't know.
Disclosed monetization
When we earn from a recommendation, we say so above the fold. Affiliate compensation never changes a rating.
