ANAHEIM, CA – SK Labs, a contract manufacturer specializing in dietary supplement capsules, tablets, and powders, has earned NSF/ANSI 455-2 Good Manufacturing Practices (GMP) certification with an “A” rating from NSF, an independent public health and safety organization.

The NSF/ANSI 455-2 certification verifies that SK Labs meets rigorous GMP requirements for dietary supplements, including quality management systems, personnel training, sanitation, equipment, and ingredient traceability.
