What does each "tested" mark actually check?

Only some marks check that the creatine amount matches the label. Others only screen for banned drugs. Here is what each program says about itself.

Quotes are from each program's own pages. "Not stated" means the pages we read didn't say. USP Verified checks the label amount too, but it lists no creatine product.

Is your brand's creatine third-party tested?

Find your brand below. Each row shows the strongest proof we found for any of that brand's creatine products. To filter single products by proof, form and cost, use our creatine comparison. 17 of the 32 brands have proof of the dose.^{*4, 8, 13, 15}

1. a Force Factor's gummies are NSF-listed. We found no record for its powder, which says "third-party tested for purity and potency" and names no program. A brand's other products can have less proof than the row shows.^{*1, 4}
2. b NSF lists Thorne's 450 g and 900 g sizes (90 and 180 servings). The 30- and 60-serving sizes (150 g and 300 g) sold on Amazon are not on the listing.^*4
3. c Naked's Amazon title says "NSF Certified." It holds NSF's contents certification, not Certified for Sport, and its listing doesn't say which one.^{*1, 4, 6}
4. d We matched Optimum Nutrition by brand and form, because Amazon's titles differ from the registry's. The registry lists "Micronized Creatine Powder" and "Creatine."^*9
5. e The Kaged product we found on Amazon is creatine HCl, a different compound from monohydrate. Informed Sport also lists its monohydrate.^*8
6. f We read this claim on the brand's own website, not on Amazon. Brand pages can change, and some load part of their text with scripts, so a claim could sit where we didn't see it.
7. g NSF lists Vital Proteins Creatine (250 g), but the listing shows no country of sale, so we can't confirm it is sold in the US. Its collagen and creatine blends are listed for the US.^*4

32 brands shown, read Oct 21, 2026. "None found" means we found no record in the places we searched. For Informed Sport, our keyword search was incomplete, so we also searched each brand by name. We left out 3 brands people search for (Cellucor, NutraChamps, Qunol) because we found no creatine product from them.^*8

How to check creatine before you buy

Three checks take about five minutes. They catch most of the gap between a claim and a record.

1. Search the program's own site. Look up your brand and product name at nsfsport.com for Certified for Sport, or at the Informed Sport and Informed Choice sites. A logo on the label or a line in an Amazon title is not proof.^{*4, 8}
2. Match the size. NSF lists certain package sizes. Thorne's 450 g and 900 g sizes (90 and 180 servings) are listed, and its 30- and 60-serving sizes (150 g and 300 g) are not.^*4
3. Read what the mark covers. Banned-substance marks don't check the creatine amount, and a factory audit checks neither. Use the table above.

1 2 3

1. 1
   Brand and product. Match both to the tub you are buying, not just the brand.
2. 2
   Lot numbers. NSF lists the lots it tested. Your tub's lot is printed on it.
3. 3
   Package sizes. 1 kg is listed, the size of our pick.

Is creatine third-party tested?
