Our Review Process

Reviews start with the ingredient list or facts panel — the form of each active ingredient and the amount per serving — then check those ingredients against published research and reference sources such as the NIH Office of Dietary Supplements. Independent certification (NSF, USP, Informed Choice) and published certificates of analysis are noted where a manufacturer provides them, and their absence is noted where it does not. Cost is compared per serving or per application rather than per package. We do not run laboratory tests of our own, and no brand pays to be included, ranked or reviewed.
