About the registries
What these certifications mean
We track three major public registries. Certification means a public registry listed the product at the time we observed it, not that we tested anything ourselves.
NSF Certified for Sport
NSF International tests for label accuracy, contaminants, and banned substances. Listed products appear in the public NSF Certified for Sport or NSF Contents Certified registries. We observe the registry; we do not conduct the tests.
USP Verified
USP (United States Pharmacopeia) tests for ingredient identity, potency, purity, and disintegration. Products appear in the public USP Verified dietary supplement directory. We observe the directory; we do not conduct the tests.
Informed Sport
Informed Sport (part of LGC Group) certifies products against the WADA prohibited list. Every batch is tested before release. Products appear in the public Informed Sport registry. We observe the registry; we do not conduct the tests.
NutraTested is not a testing laboratory. We are not affiliated with NSF, USP, or Informed Sport. We aggregate and display public registry data; all records are attributed and dated to when we observed them. Certifications can lapse: always click through to the registry to confirm current status before purchasing.
