How we research, review and update buyer-facing supplement information.
Evidence hierarchy
We give first priority to product packaging and the actual seller checkout for product and commercial claims, and to FDA, NIH/NIDDK/NCCIH and other reputable medical references for health questions. Where credible documents conflict, we report the conflict rather than choose the more attractive number.
Separating claim types
Product description and pricing are attributed to the seller. Ingredient-level clinical research is not presented as evidence that a finished supplement works. Editorial conclusions identify important limits, including missing dosage information and unverified finished-product trials.
Corrections and dates
Pages show a November 1, 2026 research review date. Claims should be rechecked when the product page, seller policy or medical literature changes. No invisible continuous monitoring is implied.
Prohibited practices
We do not invent physicians, reviews, stock levels, experimental outcomes, star ratings, supplement amounts, or FDA approvals. We avoid misleading “official website” impersonation.
