There are many hydration drinks out there, but most of them have one thing in common: sugar. Being labeled as a “hydration” drink does not make the sugar any less harmful. Artificial sweeteners are common, too, and just as unhelpful. Some electrolyte drinks attempt to hydrate, and a few are reasonable, but most do not have the appropriate osmolality — a fancy term for salt concentration — and none are adjustable. The Dr. Dan Hydration Formula is one that you can mix yourself for a fraction of the cost of store-bought drinks, and you can adjust it to your needs and taste. If you prefer it sweet, you can choose the sweetener and the amount. Check out the Hydration/Water section and try the formula at the bottom of the page.
