I know gator-aid and its like advertise that they have lots of them. And I know sometimes I feel bad if I sweat a lot and just drink water. But are they just advertising… salt? Are there different kinds of electrolytes, and if so are they interchangable?
Well, during heavy excercise, a lot more than salt is lost. Another thing lost is blood glucose. It can help you recover to replece the glucose as well, so the sugar in sports drinks can be useful as well.
