AG1 (Athletic Greens)
NSF Certified for Sport, premium price · Premium
Confirmed NSF Certified for Sport in NSF's own database across effectively the current line — the AG1 powders and flavours, Next Gen, Pro, AG Omega, Vitamin D3+K2 drops, AGZ and Essentials Gummies. That is lot-level product certification, the stricter of NSF's programmes. One correction worth making: AG1 is NOT USP Verified. Its published references to USP concern heavy-metal guideline limits it tests against, which is not the same as holding the USP mark.

AG1 (Athletic Greens)testing & certifications — FAQ
Is AG1 (Athletic Greens) third-party tested?
AG1 (Athletic Greens) reports the following quality programmes: NSF Certified for Sport (product-level, covers the AG1 powder line and other listed SKUs), NSF/ANSI 173 (AG1 Essentials Gummies), NSF/ANSI 455-2 GMP (packaging facility). NSF certification is an independent, third-party program that verifies a product actually matches 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 AG1 (Athletic Greens) NSF Certified for Sport?
AG1 (Athletic Greens) states that AG1 (Athletic Greens) products carry NSF Certified for Sport. NSF Certified for Sport screens each batch against 280+ substances banned in sport and confirms the label is accurate.
Is AG1 (Athletic Greens) made in a cGMP / GMP-certified facility?
Yes — our record lists "NSF/ANSI 455-2 GMP (packaging facility)" for AG1 (Athletic Greens). 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.
