How It Works – Isotonic Advantage
Carbohydrate depletion is a leading cause of fatigue during exercise. SIS GO Isotonic Energy Gel is designed to rapidly replenish energy by allowing fast gastric emptying and absorption—without pulling additional water into the stomach. This ensures quick conversion of carbohydrates into usable energy and helps delay the onset of fatigue, commonly known as “hitting the wall.”
