SiS
Go Isotonic Energy Gel 60 ml

SiS Go Isotonic Energy Gel is an isotonic energy gel intended for endurance athletes – runners, cyclists, triathletes, and marathon runners. Each 60ml sachet contains 22g of rapidly absorbed carbohydrates and provides 87 kcal. Thanks to its isotonic formula, it is suitable for immediate energy replenishment during intense exercise. The Variety Pack contains 7 sachets with various flavours, making it ideal for both training and racing.

SiS Go Isotonic Energy Gel is taken during physical activity, not before or after. The recommended intake is 1 to 3 gels per hour of activity. For endurance efforts lasting longer than 60 minutes, it is advisable to start with the first gel 30–45 minutes into the session and then repeat every 20–45 minutes, depending on the intensity of the effort and individual tolerance.

No, there is no need to drink water with SiS Go Isotonic Energy Gel. That is its key benefit – the isotonic formula allows for rapid absorption directly in the stomach without the need for fluids. This reduces the risk of bloating and digestive discomfort during exercise, a significant advantage over hypertonic gels that require water for proper absorption.

Yes, SiS Go Isotonic Energy Gel is suitable for both vegans and vegetarians. The product contains no animal-derived ingredients. The main carbohydrate source is maltodextrin (33%), and it also contains gellan and xanthan gum as gelling agents, acidity regulators, preservatives, and the antioxidant ascorbic acid – all ingredients are plant-based.

SiS Go Isotonic Energy Gel does not contain declared allergens – it is both gluten-free and lactose-free. The product is therefore suitable for those with lactose intolerance and those avoiding gluten. The ingredients consist primarily of water, maltodextrin, flavourings, gelling agents, and acidity regulators, with no dairy or wheat derivatives.

One SiS Go Isotonic Energy Gel sachet (60g) contains exactly 22g of carbohydrates, of which only 0.7g are sugars. The remainder is maltodextrin – a polysaccharide with a high glycaemic index that is absorbed rapidly to provide immediate energy to working muscles. The energy value per dose is 87 kcal. The gel contains no fats or proteins.

SiS Go Isotonic Energy Gel is specifically formulated to minimise digestive discomfort. Its isotonic formula eliminates the need to drink water with the gel, reducing the risk of bloating and cramps during exercise. However, more sensitive individuals may feel some discomfort at higher intakes (3 gels per hour). It is recommended to test your tolerance during training before important races and not to exceed the recommended dose.

An isotonic gel, like SiS Go Isotonic Energy Gel, has the same osmolarity as the blood, which allows for rapid absorption without the need for water. A hypertonic gel has a higher concentration of sugars – it provides energy faster, but requires fluid intake for proper absorption, otherwise, it may slow down stomach emptying and increase the risk of digestive discomfort. For runners and triathletes, the isotonic variant is more practical because it does not require coordination with aid stations.

Yes, SiS Go Isotonic Energy Gel can be combined with an isotonic drink. Since the gel does not require water, there is no risk of fluid overload. When combining a gel and a drink, monitor your total carbohydrate intake – the recommended maximum intake for most athletes is 60–90g of carbohydrates per hour. A gel (22g of carbohydrates) and a drink can together form a balanced energy strategy for long endurance events.

SiS Go Isotonic Energy Gel differs from most competing gels primarily in its isotonic formula, which requires no water – an advantage not offered by all brands. The content of 22g of carbohydrates per serving is standard in the category. The Variety Pack of 7 x 60ml allows you to try multiple flavours at once. When comparing, it is recommended to look at the composition, sugar content, caffeine presence, and price per serving.
