Evidence-first supplement research
See what top health experts claim —
then see what the science actually shows.
Search any supplement. We extract specific claims from Huberman, Attia, Patrick and others, compare each claim against PubMed research, and show you where they align — and where they don't.
We lead with supplements that have enough expert coverage and PubMed research to be useful. Experimental or thinly-covered topics stay out of the main library until the evidence base is stronger.

How this works
Expert claims, attributed
We extract specific claims from podcasts and transcripts by Huberman, Attia, Patrick, and others. Every claim is sourced to an episode with a link.
Compared to PubMed evidence
Each claim is compared against relevant published research — RCTs, systematic reviews, and meta-analyses. Evidence quality is rated and shown.
Transparent uncertainty
We show what we don't know as clearly as what we do. Evidence gaps, conflicting studies, and extraction confidence are all visible.
Quality standard
Pages are most useful when they combine attributed expert claims, PubMed-linked research, and an explicit evidence rating. Low-coverage supplements are not promoted in the public index until they have enough source material to avoid giving a false sense of certainty.
