Sports drinks, such as Gatorade, Powerade, and the various brands of vitamin water on the market are good at marketing themselves as the ultimate hydration solution. And it's true that most of these drinks do contain electrolytes and potassium, which are beneficial in combating dehydration after physical activity (or a bad hangover). But, the fact of the matter is that they're full of sugar and unnatural dyes. They're not worth the benefits they provide.
Artificial additives commonly found in sports drinks, such as wood rosin, have also been linked to cancer. Need a post-workout drink that isn't full of crap? Try water. If that's not exciting enough or you need an extra boost, get yourself some coconut water. Make sure the ingredients list is simply '100 percent coconut water' and that it doesn't contain added sugar.
