Source hierarchy

- Other reputable professional or peer-reviewed sources
Claims are classified
Product-label fact means the claim appears on the supplied current label. Vendor-reported means it comes from seller material and is not independently verified merely by repetition. Independent evidence means the statement is tied to external scientific or public-health sources.
No evidence laundering
An ingredient trial is not rewritten as a finished-product trial. A mechanism is not presented as a guaranteed outcome. Testimonials are not used as proof of efficacy, and this site does not fabricate ratings, review counts, scarcity, endorsements or clinical credentials.
Corrections
When a substantive factual error is identified, the goal is to correct the page and update its revision date. Offer terms such as price and shipping are dated because they change more quickly than product-label facts.
Commercial independence
Affiliate links can generate commission, but editorial language is not framed as manufacturer-authored content. High-intent pages disclose the relationship and identify this site as independent.
