An independent reference for people trying to compare supplements without a background in pharmacology.
This site exists because the information needed to compare two supplement bottles is publicly available and almost never assembled in one place. Federal labeling rules, what a certification mark covers, how to read a study abstract — none of it is secret, and all of it is scattered across regulatory documents most shoppers will never open.
We assemble it, in plain English, and apply it consistently. Our method is published so that our conclusions can be checked against it.
We are not doctors, pharmacists, dietitians or a testing laboratory, and we do not claim clinical credentials. We read primary sources carefully and cite them. For anything concerning your own health, talk to a qualified clinician.
