Correcting an analysis

This is the message we most want to receive. If a grading looks wrong to you, or a study we cite does not say what we claim it says, tell us which supplement and which claim, and point to the paper — a PMID or DOI is ideal. We check every report against the source and correct what needs correcting.

Evidence we missed

New trials appear constantly and we do not catch all of them. If a meta-analysis or RCT changes the picture for a supplement in our catalog, send it over. Papers that weaken a grading are as welcome as papers that strengthen it.

Press and research

Happy to explain the methodology, the grading distribution, or how the catalog is built and audited.

Partnerships

We do not accept sponsored content, paid placement or paid reviews, and no commercial relationship affects an evidence grading — see the affiliate disclosure. Retailer affiliate enquiries are welcome on that basis.

Developers and AI agents

The llms.txt file documents the free JSON API and the MCP server. If you are building on them and something is missing, say so — that feedback shapes what we expose next.
