Independent · Evidence-weighted · Rubric-scored
Supplement picks you can actually trust — scored on a public rubric.
We score every Amazon-available supplement we review on the same 6-metric rubric: third-party testing, bioavailability, clinical evidence, value, brand transparency, and form. Every score is public, every claim is cited, and no brand gets a better rank for paying more.
Why trust this site
Public 6-metric rubric
Every product scored 0-10 on third-party testing, bioavailability, clinical evidence, value, transparency, and form. Methodology public.
No brand pay-for-rank
Amazon affiliates only. No sponsorships, no "review for free product" deals. Commission rate doesn't influence ranking.
Every claim cited
Health claims link to the original PubMed study, not a secondary article. Mixed evidence is called out as mixed.
Quarterly re-verification
Rankings re-checked every quarter. "Last verified" date on every roundup. Changes documented, not silent.
