NSF Dietary Supplement Certification helps consumers and health care providers identify high quality and reliable supplements. This certification assures consumer safety by requiring rigorous outside expert contaminant testing and verifying manufacturing consistency and accuracy.
Verifies the identity and quantity of dietary ingredients declared on the product label
Ensures the product does not contain unacceptable levels of contaminants
Unlike other supplement certification programs, NSF conducts annual audits and periodically retests each dietary supplement product to ensure continued compliance against the toughest testing standard in existence today.
