Gatorade Zero was developed for athletes that prefer a performance boost and not a sugar rush. It has no sugar while maintaining the same proven hydration and fueling benefits of Gatorade Thirst Quencher. During training, your energy needs are unique. Gatorade Zero lets you replace what you’ve lost without adding more of what you may not need. When you sweat, you lose more than water. Losses in fluids and electrolytes can negatively impact performance. Gatorade Zero contains critical electrolytes to help replace what’s lost in sweat. Refueling goes beyond simply refilling. With zero calories per serving, Gatorade Zero complements your nutritional efforts so you don’t need a workout after your workout.
