Good conclusions depend on good sources. This policy explains how we choose and cite them.
Preferred Sources
- Cochrane and other systematic reviews
- Peer-reviewed trials indexed in PubMed
- Clinical guidelines and government health agencies (NIH, NIAMS, NCCIH, FDA)
- The seller’s own label and terms, for product facts
What We Avoid
- Press-release advertorials
- Unverified ratings and testimonials
- Look-alike “official” sites
- News articles used as clinical evidence
Conflicting Sources
When sources disagree, we favor the higher-quality and more recent evidence and say plainly that uncertainty exists.
Citation Proximity
We place citations on the same page as the claim they support, so readers can check them without hunting.
Sources & References
We prioritize primary product information, regulatory sources, peer-reviewed research and recognized clinical guidance. Seller claims are not treated as independent clinical evidence.
