Preferred Sources
Regulators, peer-reviewed studies, systematic reviews, official product labels/catalogs and documented seller policies.
What We Avoid
Anonymous copied claims, fake ratings, unverifiable review counts and circular affiliate citations.
Conflicting Sources
When sources disagree, we describe the conflict rather than selecting the more commercially attractive version.
Citation Proximity
Key claims should be supported close to the relevant text, especially safety, regulation and pricing claims.
Primary vs Independent Sources
Primary sources are useful for confirming what a company currently says about its own formula, price, guarantee, or instructions. They are not independent proof that a health claim is effective. For efficacy and safety questions, we give greater weight to peer-reviewed research, recognized clinical guidance, and regulatory information.
Recency and Version Control
Time-sensitive claims are checked against the most current source we can identify. When a source can change—such as a sales page or refund page—we record the review date and avoid implying that the same wording will remain in force indefinitely.
How We Handle Missing Evidence
If we cannot find reliable evidence for a specific claim, we say that the evidence is limited or unavailable rather than filling the gap with testimonials, affiliate articles, or assumptions based on a similar ingredient.
