Waterboy Workout Hydration ($25)
In addition to a higher sodium content (of 1,000 mg per serving), Waterboy Workout Hydration powders include L-glutamine, an amino acid that may help reduce exercise-related muscle damage, according to a review of 55 studies in the journal Nutrients. The addition of 400 mg of potassium, 50 mg of magnesium, vitamin C, and vitamin B12 make these a solid choice for regular exercisers. Plus, they taste great: the packets come in blue raspberry, fruit punch, lemon lime, and strawberry lemonade flavors, each sweetened with stevia.
Customer Quote: "I like that it's not too sweet as other brands that I've tried before, and that you actually feel hydrated. I noticed that I sleep and recover better, because I take it when I go to the gym at night. So far it's been better than other brands I've tried."
