The SiS Isotonic Energy Gel is a flavourful energy gel rich in energy. With a unique formula, SiS created an easily digestible gel. The SiS Go Isotonic Energy Gel was the world's first isotonic energy gel. The human body quickly and easily absorbs SiS gels due to their isotonic concentration. This provides the body with a rapid energy boost. The SiS Go gels are also exceptionally suited for consuming during exercise at fast heart rates, when it's harder to digest food. Another upside is that you can consume the SiS Go Isotonic Energy Gels without any water or sports drinks. This makes the gels ideal during intense exertion when it's hard to drink large quantities of water. Due to the isotonic concentration, this gel is also suited for cyclists with a sensitive digestive tract. It's for good reason that the SiS Go Isotonic Energy Gels were crowned the winner of the Queens Award: a prize for exceptional innovation. The Go Isotonic Energy Gels are often prominently present at pro sporting events and consumed daily by thousands of endurance athletes over the whole world.
