How we evaluate supplements
We distinguish what a label verifies from what a manufacturer advertises. For proprietary blends, we flag when individual ingredient amounts are unavailable. Ingredient research is not treated as proof that a finished multi-ingredient product produces the same outcome.
Important: Dietary supplements are regulated differently from drugs. FDA states that structure/function claims are not pre-approved and must be truthful and non-misleading; supplements making such claims carry a statutory disclaimer.
