What the mark checks, and what it does not

Checks: the facility is audited to GMP, production lots are tested for label claim (the ingredients and amounts on the label) and for contaminants; Certified for Sport adds a screen of every lot for banned substances.

Leaves out: it is silent on whether the dose is clinically useful, and a certified flavour does not certify the other flavours.

Frequently asked questions

What does NSF/ANSI 173 and NSF Certified for Sport certify?

That the facility is audited to GMP, production lots are tested for label claim (the ingredients and amounts on the label) and for contaminants; Certified for Sport adds a screen of every lot for banned substances. What it leaves out: it is silent on whether the dose is clinically useful, and a certified flavour does not certify the other flavours.

How do I check whether a product is NSF/ANSI certified?

Search the exact product name at info.nsf.org → Certified Dietary Supplements (search by product name, then match the exact listing). 3,053 listings were in the registry as of Tuesday, August 25, 2026; a brand appearing there does not mean every product does.

What is the cheapest NSF/ANSI-listed supplement per day?

NatureWise Vitamin D3 2000 IU in Olive Oil at $0.040 per day of its studied dose (Vitamin D3 2000).
