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?
This is quite true. The only people who need to worry about this on the regular are endurance athletes (and people with equivalent jobs). Anything where you are working at an elevated heart rate and sweating for hours or days. Not common for joggers or people who shoot hoops after work
