We all know we should be drinking lots of water, but is H₂O alone enough? In the past few years, a new category of beverages has blown up: electrolyte drinks. These products have been popular with endurance athletes for a while, but now it seems like Olympians and civilians alike are adding powders to their water on a daily basis.
Most of the time, we can get enough electrolytes from food. But in hot weather and/or when exercising, they can be a helpful tool for staying hydrated.
