The GU Hydration Drink Tabs 8 Tube Pack is an ideal solution for athletes on the go, increasing hydration before, during, and after workouts. Each tube contains 12 tablets, with 96 individual servings total for the 8 Tube Pack. Simply drop one tab into 16 ounces of water, watch it fizz, and you're ready to bike, run, or hit the gym with increased hydration. Ideal for warm weather workouts and intense efforts alike, each tab has 320 milligrams of sodium to replenish precious electrolytes lost during perspiration. Reformulated with xylitol sweetener to reduce GI distress when compared with supplements using sorbitol, these tabs are gentle on the stomach when you're working out. They also use all natural Stevia, which is a plant based sweetener.
