United States Pharmacopeia

United States Pharmacopeia appears in Why is there a supplement craze if they don’t even work? through Marion Nestle’s discussion of supplement testing marks. The episode says a USP mark can indicate third-party testing for listed ingredients, accurate amounts, and non-harmful levels.

The source uses USP as a practical consumer signal, not as evidence that a supplement works for healthy people. Its role is inside Third-Party Supplement Testing and Supplement Label Accuracy, where the first question is whether the product matches the package.
