For product identity, formula and current offers, we prefer seller pages, labels and checkout information.
Preferred Sources
For product-controlled facts we may use the current seller website, checkout or label. For medical and scientific context we prefer government health agencies, peer-reviewed journals, systematic reviews and established academic or clinical organizations.
What We Avoid
We do not rely on anonymous reposts, copied affiliate articles, unsupported testimonials or search snippets as primary evidence for health claims.
Conflicting Sources
When credible sources disagree, we describe the disagreement and avoid presenting a stronger conclusion than the evidence supports. Seller claims are kept distinct from independent research findings.
Citation Proximity
Important factual or scientific statements should be supported close to the relevant text rather than buried in a distant references list whenever practical.
Sources & References
Source quality matters more than source quantity. A small number of directly relevant, higher-quality references is preferred over a long list of weak or repetitive citations.
