Questions, corrections and requests to use material from this site are all welcome. Everything sent through the form below reaches one person, and it is read.
What to write about
Corrections. If something on this site is wrong, out of date, or has been overtaken by better evidence, please say so. Corrections are made openly rather than quietly, and the article carries the date it was reviewed. Naming the article and the specific line helps.
Permissions. Requests to quote, translate or republish material from this site. Say which article and where it would appear.
Anything else about the site itself — a broken page, a source you think is missing, a topic worth covering.
What not to write about
Please do not send personal health questions. Nothing on this site is medical advice and no reply from here could be either. Questions about your own health, your medications or whether a supplement suits you belong with a doctor or pharmacist who can see your history and ask you follow-up questions. That is not a brush-off — it is the only honest answer this site can give.
What happens next
Please allow a few business days for a reply. This is a small independent site written by one person, not a company with a support desk. Messages that need a correction made are dealt with first.
No email address, postal address or phone number is published here. The form is the way in, and it is enough.
