Testing list
NSF Certified for SportAlso NSF/ANSI 173, like Thorne

Why we pick it Thorne’s main selling point is its testing. BulkSupplements is the only cheaper creatine here on both of the same NSF lists: NSF/ANSI 173 checks that the label is right and the powder is clean, and NSF Certified for Sport also screens for drugs banned in sport. It is less than half the price a day, and our best creatine guide names it as the lower-cost NSF option.

What you give up NSF lists fewer of its lots: 10 against 77 for Thorne, so if you are drug-tested, check your lot number on the NSF listing, or stay with Thorne. It comes in a resealable bag, not a tub.

Questions people ask

Is cheaper creatine as good as Thorne?

Yes, if it is creatine monohydrate. Every product here is 5 g of creatine monohydrate a scoop, the form most studies used. What changes with the price is the testing and the container, not the creatine. See forms compared.

Is Thorne creatine Creapure?

Thorne does not say so: neither its label nor its website names Creapure. If you want Creapure, see which tubs use it.

Is creatine safe to take every day?

For most healthy adults, yes. Studies have given up to 30 g a day, and some have run as long as 5 years; the International Society of Sports Nutrition reviewed them and found creatine safe and well tolerated (Kreider 2017). Ask a doctor first if you have kidney disease, are pregnant or breastfeeding, or are under 18.

Will creatine change a kidney blood test?

It can. Creatine raises creatinine, the marker most kidney blood tests read, so results can look worse while the kidneys work the same. A 2025 review of the studies found a small rise in creatinine and no change in measured kidney function (Naeini 2025). Tell your doctor you take it before a blood test.

How we picked

We compared Thorne Creatine with the creatine monohydrate powders our creatine guides score, priced each on Amazon, and checked each against NSF Certified for Sport, NSF/ANSI 173, Informed Sport, Informed Choice and USP Verified. Thorne’s case is its testing, so we picked the cheaper creatine on the same two NSF lists. Nutricost, another common swap, costs about the same as our pick but is not on a testing list we check; see Nutricost vs Thorne.
