I received a free sample of the Gatorade Hydration Booster in Strawberry Watermelon. I love how you just add it to water, and it is only 30 calories. It tastes good so, I don't feel bad adding it to the water. And I keep this in my gym bag, and I add it to my water bottle while I am working out. I no longer need to worry about getting extra hydration and it improves my performance.
