In the United States, claims for supplement products are governed by two federal agencies—FDA and FTC—but they want different things. FDA polices claims to ensure they are fit for the product that carries the claim. FTC isn’t concerned with product type, but enforces that claims are truthful (not misleading). To add to the confusion, a study may satisfy FTC’s demands, but may not be able to support a claim in FDA’s eyes. To help sort out claims substantiation, attorney Justin Prochnow, shareholder, Greenberg Traurig LLP, discusses these complexities with Sandy Almendarez, editor in chief, INSIDER, at Natural Products Expo West 2017.
