The Science Says: Juice delivers antioxidants that mop up the harmful free radicals produced when you exercise. A daily dose of cherry juice may help ease inflammation that causes sore muscles.
What It's Best For: Post-exercise. Fructose, the primary sugar in fruit, takes longer to digest than other sugars (like those in sports drinks), so drinking juice during or before exercise may cause stomach cramps.
