With a legacy over 40 years in the making, Gatorade Thirst Quencher is the most scientifically researched and game-tested way to replace electrolytes lost in sweat. It hydrates better than water and is trusted by some of the world's best athletes, but non-athletes will enjoy its flavorful benefits, too. G Zero with Protein has no sugar and maintains the same proven hydration benefits of Gatorade Thirst Quencher, and now offers 10 grams of whey protein isolate to help kick-start your recovery after training.
