                                According to the National Institutes of Health (NIH), third-party certification is crucial for ensuring the identity, purity, and potency of dietary supplements, and for this reason, many people ask: **Are all supplements on Fullscript third party tested**? While Fullscript requires all partner brands to hold a current Good Manufacturing Practice (cGMP) certification, not every single product in its extensive catalog has a third-party testing seal, though many do.
