The Science Says: Coconut water naturally contains some electrolytes (potassium, sodium, calcium, magnesium). But research on the drink is still limited. One 2002 study found that exercisers who consumed coconut water drank more, but weren’t any more hydrated than those who drank water or a sports drink.
What It's Best For: If you want something other than water that’s natural. Be mindful of the extra calories.
