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?
Make your own. The ratios are out there, just takes salt (NaCl), maybe some salt substitute (KCl), sugar, etc.
I use the WHO reduced osmolarity ORS recipe which uses sodium citrate as well, it has worked pretty well.
