About NutraTested

NutraTested is the independent transparency and evidence index for dietary supplements. We aggregate third-party certification data (NSF, Informed Sport, USP), published analytical lab tests, human research evidence grades, and publicly stated expert-stack information into one attributed, dated record per ingredient and product.

We track testing. We do not perform it. Every test result shown names who ran it, when it was published, and links to the primary source.

Our editorial wall is absolute: no brand pays to change a grade, ranking, or result. Affiliate links are clearly labeled and appear only on products that pass third-party testing. Any advertising or data partnerships are kept strictly separate from our ratings.
