How we evaluated it
Why we chose it What put it on our list
- NSF lists Thorne Creatine in several forms. The main listing covers the 450 g and 900 g powder (one scoop is 5 g) and shows 69 lots. A second listing covers the 30 stick packs.
- Thorne’s product data lists one ingredient: creatine monohydrate, 5 g per scoop, with no other ingredients.
- Thorne explains the mark as testing every batch for compliance with the label and for nearly 300 substances banned by major athletic organizations.
- The price is clear: $44.00 for 90 servings on Thorne’s site, about $0.49 a serving.
Trade-offs What to weigh before you buy
- It costs about a third more per serving than Nature Made’s 90-serving tub at Nature Made’s price ($0.37), and more than three times BulkSupplements’ 1 kg price ($0.15), for the same single ingredient.
- Thorne’s page shows no batch certificate and does not say where the creatine is made. NSF’s listing is the independent record.
- Thorne’s description credits creatine with supporting cognitive function and reducing muscle cramps. Our creatine guide finds the brain evidence smaller and mostly in people with low creatine, and does not cover the cramp claim.
- Our creatine guide says the safety findings apply to healthy people. Ask a clinician first if you have kidney or liver disease.
What to know Details worth knowing first
Our creatine guide says plain creatine monohydrate is the form to choose, at 3 to 5 g a day. Thorne’s is exactly that: one ingredient, 5 g a scoop.
The reason it is listed is the NSF database. Supplements are loosely regulated, so a label can be wrong about the dose. NSF’s Certified for Sport program tests products against their labels, screens for banned substances, and publishes lots. Thorne’s main listing shows 69 lots, the longest list of the three creatines here.
You are paying for the brand and the testing record, not a different ingredient. At about $0.49 a serving it is the dearest of the three we list, though the gap to the cheapest is about a third of a dollar a day. If that matters, BulkSupplements and Nature Made are NSF-listed too.
Quality & testing How it measures up against our checklist
- Third-party tested
- Yes
- Tested by
- NSF (Certified for Sport)
| What we checked | What we found |
|---|---|
| Research behind the ingredient Verified | Creatine monohydrate, 5 g a scoop. The International Society of Sports Nutrition position stand (cited in our creatine guide) finds supplementation raises muscle creatine and improves high-intensity exercise performance, and reports it safe in healthy people at up to 30 g a day for 5 years. |
| Third-party tested Verified | Listed in NSF’s Certified for Sport database as “Thorne Creatine”: powder, 450 g and 900 g, serving 1 scoop (5 g), 69 lots shown (listing 1495542). Another listing (1204244) covers a 453 g powder, and a third (1663109) covers 30 stick packs of 5.15 g. |
| A plain label Maker’s claim | Creatine monohydrate 5.0 g per scoop. Thorne’s product data lists no other ingredients. No proprietary blend. |
| Claims that match the evidence Maker’s claim | Mostly. The page says creatine supports muscle performance and strength, which our guide supports. It also says it supports cognitive function and “reduces the frequency of exercise induced muscle cramps”; the first is weaker in our guide and we did not check the second. |
| Honest cost Maker’s claim | $44.00 for 90 servings of 5 g on Thorne’s site, about $0.49 a serving, as seen 2026-10-22. |
| Purity and origin Maker’s claim | Thorne says each ingredient goes through several rounds of quality control for purity, potency and consistency. No results are published, and the country of origin is not stated. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.
