Supplement Brand Report Cards
Most brand reviews are opinion. We grade supplement brands on data instead. Three things nobody else combines: certification, cost per dose, and FDA reports in honest context. Each report card is computed live from our own catalog, not hand-written claims.
-
Thorne
31 products tracked. Certification rate, price vs category median, and FDA adverse-event reports, all computed live.
-
Nature Made
15 products tracked. The certification standout: a high USP Verified rate at mass-market prices, with the highest FDA report count on this site, a volume-bias case study.
-
NOW Foods
103 products tracked, the widest catalog we cover. Enormous selection, a very low third-party certification rate.
-
Sports Research
15 products tracked. A smaller catalog with some genuine third-party certification, and the fewest FDA reports on this site.
-
Doctor's Best
22 products tracked, zero third-party certified. Frequently our best-value pick: you trade verification for price.

About our data
Every report card uses the same catalog and cost-per-dose method as the site. We add FDA CAERS and FAERS adverse-event data for safety context. See our methodology and safety-scoring approach for the full detail.
