How we rate pharma companies and products

Every score on pharmaranks is built the same way: from independent data sources, combined by a published formula, with no influence from the companies we rate.

The sources

We weight sources by trust. Regulatory data (the FDA's openFDA recall records, official drug labels) carries more weight than crowd reviews, which in turn outweigh a single unverified opinion.

The formula

Each source's score is first shrunk toward a neutral baseline based on how much data backs it — one five-star review should never outrank a long track record. We then take a trust- and volume-weighted average across sources.

Why transparency matters

For health information, showing your work is the whole game. That's why every product and company page lists the per-source breakdown, and why this methodology is public.

Ratings are independent and are never affected by sponsorship or affiliate links.
