Send a note about a source, fact, or unclear sentence

Send source corrections, not medical questions

Use the form for three kinds of note: (1) a fact or source that may be wrong; (2) a study summary that isn't clear; or (3) a question about the site's purpose. If a paper link is broken, name the page and the study beside it.

The form can't give medical answers or choose a dose, find the drug, or handle product requests. The site offers no doctor or nurse, and it prescribes or sells nothing.

I read each note, but I can't promise a quick reply. A claimed error may take time to check against the published paper.

Give enough detail to check the exact claim

The form asks for your name, email address, and message. For a correction, include the page address, the exact claim, and the paper that you think gives a better answer.

Those details identify the right sentence without guesswork. A proposed change is checked against the published paper before it appears.
