Third-Party Tested Creatine: Reviewed Product Evidence
Last updated:
The useful question is whether the exact creatine product you plan to buy has a current, relevant certification record. A claim about another product from the same brand is not enough.
Our review currently includes 1 brands with a matching product record in this category. This is coverage of our review, not a market-wide count or a ranking of the best products.

These records cover the listed products and variants. Match your product, region and lot against the current registry before buying. Evidence reviewed 2026-09-07; evaluated 2026-09-19.
Compare the ingredient and the finished product
Creatine monohydrate is the most widely used and studied form. Other forms have not demonstrated superior performance across the outcomes reviewed by the NIH Office of Dietary Supplements. That ingredient evidence does not establish the quality of a particular brand or batch. Read the NIH exercise and performance fact sheet.
Record the amount of creatine per serving, other ingredients and the exact product name. A branded ingredient or supplier statement should be checked separately from certification of the finished product.
Check the relevant sports program
NSF/ANSI 173 and NSF Certified for Sport are distinct programs. The Sport program adds screening for prohibited substances; a general NSF listing is not the same credential. NSF explains the difference.
Verify a listing in four steps
- Search the official certifier directory for the full product name.
- Match the formulation, flavor, package size and region to your purchase.
- Check the current listing and any lot or batch information it provides.
- Ask the certifier or manufacturer about missing or conflicting details before treating the claim as established.
Use the NSF Sport directory, NSF dietary supplement listings, Informed Sport, or Informed Choice as appropriate to the program named on the product.
Common questions
Which creatine products have reviewed certification records?
The table on this page includes only current reviewed records explicitly assigned to this product category. An empty table means our coverage is incomplete, not that certified products do not exist.
Does certification cover every product from the same brand?
No. Match the exact product, formulation, flavor, size, region and listed lot to the registry. A record for another product category does not establish this product’s certification.
Why is a certified product listed under an unrated brand?
A specific product record can be reviewed before the brand’s certification and regulatory coverage is complete. We withhold the broader score until both reviews are complete.
Our third-party testing guide explains the broader review. Read the evidence and scoring method.
