Water is essential, but water alone doesn't properly hydrate the body or satisfy your craving for taste. Shake, flip the cap and squeeze to stylize and fortify your water or drink to easily hydrate and replenish necessary electrolytes lost by the body through sweat, exertion and exercise. It absorbs quickly and restores the body to its proper electrolyte and fluid balance. The FastServ Beverage Enhancer with fruit punch flavor contains no calories, caffeine or sugar.
