Editorial Policy

Evidence before hype.

Source hierarchy

For health claims we prefer systematic reviews, meta-analyses, randomized trials, government health agencies and current manufacturer labels for product composition. Merchant pages are evidence of what a merchant says—not independent proof that the claim is true.

Product claims

We distinguish ingredient-level evidence from finished-product evidence, mechanisms from outcomes, association from causation, and deficiency correction from enhancement in already-sufficient people.

Corrections

Health evidence, labels and purchase terms change. Pages display update dates and should be revised when material information changes.
