Schwabe North America adheres to standards that exceed even those of the new dietary supplement Good Manufacturing Practices (GMPs). We are an FDA-registered drug manufacturing establishment, and as such, we are regularly audited by the FDA. We test every lot of every product for identity, purity and potency, and all SNA products are tested for stability and bioavailability. We also voluntarily hold many other certifications and registrations above and beyond regulatory requirements. Doing so enables us to stand behind the safety and consistency of our products.
