Ideal for cyclists, runners and endurance athletes who want a portable, water-free carbohydrate source for training and racing.
SIS GO Plus Isotonic Energy Gel is a ready-to-use liquid carbohydrate gel for endurance rides, races and high-intensity training. The isotonic formula is designed to be taken without additional water, giving you a compact way to carry fuel without adding another bottle or bulky fluid volume.
Each sachet provides 22 g of maltodextrin-based carbohydrate and 87 calories. The liquid texture is easy to take on the move: tear off the top and squeeze it directly into your mouth whenever you need it. The Blackcurrant flavour offers a practical alternative to solid food when intensity is high or your appetite has dropped.
For longer sessions, SIS suggests using 1–3+ gels per hour as part of a broader plan targeting 60–90 g of carbohydrate per hour. You can combine it with other SIS energy supplements to adjust your intake. It is suitable for vegan, vegetarian, lactose-free, gluten-free, wheat-free, nut-free and soya-free diets, and is Informed Sport Registered.
