SiS GO Isotonic Energy Gels

Science in Sport made the world's first isotonic gel. SiS GO Isotonic Energy Gels deliver an easily digestible and quick supply of carbohydrates. These gels are equal in osmotic pressure (containing the same number of particles as body fluids) and are less likely to cause stomach distress. The isotonic formula addresses the high sugar content of gels that can sometimes cause GI distress. They don't require you to drink water with them. The GO Isotonic Energy Gels are used by some of the world's top cycling teams and are Informed Sport Certified.
