How to Evaluate Supplement Claims
A framework for separating seller claims, ingredient research and evidence about a finished product.
Three evidence buckets
- Seller claim: what the marketer says.
- Ingredient evidence: research on an ingredient, form or dose.
- Finished-product evidence: research on the actual formula being sold.
Do not silently substitute one bucket for another.
Regulatory baseline
FDA distinguishes health, nutrient-content and structure/function claims. FTC guidance says health-related advertising must be truthful, not misleading, and adequately substantiated.
