    About SiS GO Isotonic Gels

    The SiS GO Isotonic Gel was the world?s first isotonic gel effectively delivering an easily digestible and quick supply of carbohydrate for energy during exercise. SiS GO Isotonic Gels are designed to be consumed without water meaning that you can ensure rapid delivery of carbohydrate to your muscles without the feelings of being bloated that can sometimes occur with over-drinking.

    Why should I take this gel?

    Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. In addition to ensuring optimal carbohydrate stores before exercise, delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue. As such, SiS GO Isotonic Gels represent a highly practical solution to your in-training and competition fuelling strategy by giving you with a quick supply of 22 grams of carbohydrate per gel. Gels can easily be carried in your pocket or your race belt without the requirement for bulky bottles.

    Recommended Usage

    Consume 1-3 gels per hour to deliver approximately 60 grams of carbohydrate and maximize carbohydrate utilization rates. Where hydration is also important, SiS GO Isotonic Gels can also be consumed with SiS GO Hydro or with SiS GO Electrolyte to ensure a combination of both energy and fluid delivery during exercise.
