Corrections are especially welcome. If a number here looks wrong, or a source does not say what the page claims it says, that is worth knowing and it will be fixed.
Who runs this site
HydrationGuide is run by Reede Taylor, an independent operator based in the Netherlands. It is not a company, a clinic, or a media business, and it has no staff. There is no relationship with any supplement or drinks manufacturer.

What to expect
This is a one-person site, so replies are not instant. Medical questions cannot be answered: nobody here is a clinician, and individual advice is exactly what the site does not provide. For anything about your own health, please ask a doctor or pharmacist.
