Evidence hierarchy

- NIH, NCCIH, FDA and FTC guidance.
- Peer-reviewed research when needed for a specific ingredient question.
- Promotional reviews only as secondary market context.
No invented firsthand experience
We do not say we “tested,” “used” or “lost weight with” a product unless that actually occurred and can be documented. Affiliate compensation never changes that rule.
Updates and corrections
Supplement formulas and merchant terms can change. Pages should be rechecked when the product label, checkout, or authoritative guidance changes.
