NSF GMP Certification
From the NSF website: In the last decade, the dietary and nutritional supplements industry has grown tremendously. The fact that these products do not receive the same regulation as prescription or over-the-counter drugs raises questions in the minds of many consumers. This is why NSF developed the nation’s first independent testing standard and product certification program strictly for dietary supplements.
The program protects consumers by testing for harmful levels of contaminants and certifying that supplements contain the ingredients listed on the label and nothing else.
A Truly Independent Supplement Certification Program
NSF is the only independent, third-party testing organization that offers true testing of dietary supplements. NSF does not simply evaluate test data submitted by manufacturers or analyze just a single sample of a product and give it our okay. We conduct product testing in our own accredited laboratories to confirm that the actual contents of the supplement product match those printed on the label. We also check to make sure no unlisted ingredients or potentially harmful levels of impurities are present in products that carry our certification.
With NSF certification, you get the continued assurance that only our ongoing testing programs can provide. Unlike some other programs, NSF conducts annual audits and periodically retests each dietary supplement to ensure continued compliance against the toughest testing standard in existence today.
