gatorade and powerade are full of sugars and fillers. I am not sure why people think they actually do a good job of hydrating. actually I do know, millions of dollars of advertising where people think athletes drink that shit lol. it would be like drinking a glass of water along with 2 tablespoons of pure sugar.
best way to re-hydrate is good ole water.. get an ionizer you can plug up to your sink and you are g2g
