FitTools is written and maintained by one person. Corrections, source queries, partnership and press all reach the same inbox, and a correction gets read first.

What to send

  • A correction. If a number or a citation on this site is wrong, say which page. These get read first, and fixing them is the whole point of showing the sources.
  • A source query. Where a figure came from, or why one study was used over another.
  • Partnership or press.
  • Your data. Access, correction or deletion of anything held about you. See the privacy policy.

One person answers these, so a reply may take a few days.

What this cannot be

Not a medical service. We cannot interpret your blood results, tell you what to take, or advise on symptoms, by email or anywhere else on this site. For anything about your own health, speak to your GP or pharmacist. In the UK, call NHS 111 for urgent non-emergency concerns, and 999 in an emergency.
