Gatorade is pure garbage. If you remember when Gatorade first came out, it was pale green/yellow and it tasted like sweat. It had a lot of water, a LITTLE SUGAR AND A LITTLE SALT - What you actually need to rehydrate.
Since the taste of sweat doesn't sell, they added 10x more sugar (or better yet nasty Sucralose), freakish flavors, unnatural colors, and 100000% more marketing. Now every sucker thinks they need it. Just like bottled water.
Brilliant marketing, useless product. But it sure tastes good! Heck, if a person walks into a 7-11 and a bottle of water and a bottle of Gatorade cost the same, what would most people buy?
