If this is a medical emergency
Please contact your local emergency services or go to an emergency department. We are an education site, we are not a clinic, and we cannot help with an emergency.
Email us
The most reliable way to reach a person. Questions about the science, a product, a correction, or your data all land in the same inbox.

If it is easier to just talk it through. Bring your questions, and your labs if you have them. No pitch.
Look it up first
Privacy and your data
To see what we hold about you, get a copy, or have it deleted, email us and say so. We will act on it and we will not make it difficult.
What to expect
We aim to reply within five working days. Corrections to the science get looked at first, because a wrong claim sitting on a health site is the thing most worth fixing quickly. If you have spotted an error, please include the page address and what you think is wrong. We would genuinely rather be corrected than be confident.
What we cannot do by email
We cannot diagnose you, interpret your labs as a clinical assessment, or tell you to start or stop a medication. That is not modesty, it is the line between education and practising medicine on someone we have never examined. We can explain the mechanism, show you the research, and help you work out what to ask a clinician.
