SiS GO Isotonic gel was the world’s first isotonic energy gel to provide a quick, digestible carbohydrate supply during exercise. SiS GO Isotonic gels are designed to be consumed without water, allowing for rapid delivery of carbohydrates to the muscles without the bloating sensation associated with excessive fluid consumption. Why should I take this gel? Running out of carbohydrate stores during training is one of the main causes of fatigue. In addition to maintaining optimal carbohydrate stores and hydration before training, bringing in additional fluids and carbohydrates during exercise is a perfect way to improve performance and race times, as well as slow the onset of fatigue. Therefore, SiS GO Isotonic gels are a practical, pocket-friendly solution for your training and competition supply strategy, with a quick 22g carbohydrate supply via gel. The gels can be carried easily in your pocket or running belt without the need for bulky water bottles.
