Generally not. When you exercise, you lose some electrolytes via sweat, but you are unlikely to deplete your body’s stores under ordinary circumstances. For example, you can easily replace the 200-600 milligrams of potassium you might lose in an hour of hard training by eating a medium to large banana (450-600 mg potassium). You can also easily replace the 800-1,400 mg sodium lost in two pounds of sweat by enjoying some spaghetti with tomato sauce or some chocolate milk with a bagel and peanut butter. Athletes who do need to worry about replacing electrolytes include those who will be sweating hard for more than three or four hours.

     Keep in mind, most health organizations recommend we reduce our sodium intake, given the average American diet contains more than enough sodium! A high sodium intake leads to high blood pressure and increased risk of stroke...
