Sources Policy

Product identity, price and seller terms are sourced as close to the current seller or label as possible. Scientific claims prioritize government health agencies, systematic reviews, meta-analyses and peer-reviewed human research.

Affiliate pages and seller testimonials may help identify claims to investigate, but they are not treated as independent proof. Consumer reviews are labeled as consumer reports and are not clinical evidence.

When sources conflict, we show the conflict or choose the more authoritative/current source rather than silently blending them.
