Proco publishes research summaries about the brain, sleep, stress and mood. We also sell supplements. Those two facts are in tension, and this page sets out how we handle it — what we check before publishing, what we will not claim, and what we do when we get something wrong.
Every substantive claim — sample size, effect size, p-value, confidence interval, dose, guideline grade, journal, year — is checked against the paper itself, not against a summary of the paper. Where a source cannot be retrieved, the claim is removed rather than softened or replaced with a plausible-looking figure.
Five specific things we look for, because they are the errors we have actually made:
In 2026 we audited every article on this site against its own sources. The audit found errors in most of them — roughly 170 corrections across the library. That is an uncomfortable number to publish and it is the honest one.
What we did with it:
If you think something here is wrong, tell us. Point at the claim and, if you have it, the source. We would rather be corrected by a reader than keep an error.
We want to be precise about this, because it would be easy to imply more than is true.
The articles on this site have not been reviewed by a clinician. They are written from primary sources and checked against them, but that is editorial verification, not clinical review. Where an article has been clinically reviewed, the reviewer's name appears on that article. Where no name appears, no clinical review has happened.
We hold back the articles where that distinction matters most. Several finished pieces on neurological and diagnosed mental-health topics are written but unpublished, waiting for a suitably qualified reviewer, and we would rather leave a gap on the site than publish clinical content nobody qualified has read. We are working on arranging that review.
Separately, and because it does not depend on that review to be useful, we publish a composition reference for clinicians: what is in each product and at what dose, the two products whose blend amounts our manufacturer will not release, the interactions we think matter most in practice, and a plain list of what we have not tested. It is a statement of composition rather than a clinical recommendation, which is why it can stand while the articles wait.
The clearest test of an evidence claim is what a company does when the evidence does not help it. Some examples currently published on this site:
We do not claim to be free of commercial bias. We claim to make it visible.
