Preferred Sources
Government health agencies, peer-reviewed research, product labels and the seller for seller-specific facts.
What We Avoid
Unverifiable testimonials, anonymous forum claims as proof, and sources that copy each other. We match each source to the claim it can actually support.
When Sources Conflict
We show both and say which is stronger and why.
Citation Proximity
Sources appear on the page where the claim is made, as clickable links.
