Our methodology
We use an evidence hierarchy designed to keep product marketing, scientific evidence and consumer anecdotes separate.
- Primary product information: Supplement Facts, official seller pages and current commercial terms.
- Regulatory and government sources: FDA, NIH, NCCIH and other recognized health authorities where relevant.
- Peer-reviewed research: randomized trials, systematic reviews and meta-analyses receive more weight than laboratory studies.
- Applicability: we check dose, formulation, route, population and outcome before using a study to support a product-level statement.
- Finished-product evidence: studies of the actual commercial formula are treated as more direct than studies of isolated ingredients.
- Consumer reports: useful for identifying possible patterns, but never treated as clinical proof.
What we do not do
- Invent customer ratings
- Claim FDA approval for dietary supplements without evidence
- Turn ingredient studies into proof of a finished product
- Publish fake coupon codes
- Use “clinically proven” as a substitute for describing the actual study
