Optimum Nutritiontesting & certifications — FAQ
Is Optimum Nutrition third-party tested?
Optimum Nutrition reports the following quality programmes: Informed Choice / Sport (select), cGMP. Third-party testing checks a product's identity, potency, and purity against its label. We reproduce what the brand publishes; where the certifier keeps a public registry (NSF, USP, Informed Sport), look the specific product up there before relying on it — a company-wide claim is not a batch certificate.
Is Optimum Nutrition made in a cGMP / GMP-certified facility?
Yes — our record lists "cGMP" for Optimum Nutrition. cGMP (current Good Manufacturing Practice) is the FDA's manufacturing-quality standard for supplements; it governs how a product is made but, on its own, is not a test of the finished product.
How we assess supplement brands
Supplements aren't FDA recall-rated like prescription drugs, so we don't assign a recall-safety score here. Instead we report what a brand is independently verified for — NSF, NSF Certified for Sport, USP Verified, Informed Sport, cGMP, and batch testing — the signals that actually separate supplement quality. This is general reference, not medical advice; always consult a professional.
