How We Research Supplements
Our evidence hierarchy for dietary supplements and prostate-health content.
Evidence hierarchy
For health questions, we prefer government health agencies, clinical guidelines, systematic reviews, peer-reviewed human trials and authoritative medical institutions. Merchant pages are useful for verifying what a seller currently claims, sells and promises—but not for independently proving efficacy.
Finished formulas vs ingredients
We do not assume a positive ingredient study proves a multi-ingredient commercial formula works. We look for dose, form, population and outcome relevance.
Commercial research
For price, guarantee, directions and current formula information, we check current merchant materials and clearly label those facts as merchant-provided.
