OSG adheres to strict manufacturing standards. The Food and Drug Administration requires dietary supplement manufacturers to follow Good Manufacturing Practices (GMP) for dietary supplements (21 CFR, part 111).
We at OSG voluntarily follow the more stringent GMP for pharmaceuticals as the basis for our quality assurance program.
GMP regulates virtually every aspect of manufacturing, including facility design and maintenance, raw material specification and control, supplier validation, product design, testing and more.
Such voluntary adherence to GMP for pharmaceuticals means that we treat nutritional supplements with the same care that goes into the manufacturing of other over-the-counter products.
Also, where applicable, we voluntarily test supplements to make sure they meet trusted United States Pharmacopeia (USP) standards and specifications for potency, uniformity, and disintegration.
