Developed for athletes that prefer a performance boost and not a sugar rush. 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. Gatorade Zero has no sugar while maintaining the same proven hydration and fueling benefits of Gatorade Thirst Quencher. Refueling goes beyond simply refilling.
