SiS
Go Isotonic Energy Gel Variety Pack 7 x 60 ml

SiS Go Isotonic Energy Gel is an isotonic energy gel designed for endurance athletes – runners, cyclists, triathletes, and marathon racers. Each sachet (60 ml) contains 22 g of fast-absorbing carbohydrates and delivers 87 kcal. Thanks to its isotonic formulation, it is ideal for instant energy replenishment during intense exercise. The Variety Pack contains 7 sachets in a range of flavours, making it perfect for both training and racing.

SiS Go Isotonic Energy Gel should be taken during physical activity – not before or after. The recommended dosage is 1 to 3 gels per hour of activity. For endurance efforts lasting longer than 60 minutes, it is advisable to take your first gel 30–45 minutes after setting off, then repeat every 20–45 minutes depending on exercise intensity and personal tolerance.

No, SiS Go Isotonic Energy Gel does not need to be taken with water. This is its key advantage – the isotonic formulation enables rapid absorption directly in the stomach without the need for fluids. This reduces the risk of bloating and digestive discomfort during exercise, which is a significant benefit over hypertonic gels, which 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 primary carbohydrate source is maltodextrin (33%), and the gel also contains gellan gum and xanthan gum as gelling agents, acidity regulators, preservatives, and the antioxidant ascorbic acid – all ingredients are of plant origin.

SiS Go Isotonic Energy Gel contains no declared allergens – it is both gluten-free and lactose-free. The product is therefore suitable for those with lactose intolerance as well as those who avoid gluten. The formulation consists primarily of water, maltodextrin, flavourings, gelling agents, and acidity regulators, with no dairy or wheat derivatives.

One sachet of SiS Go Isotonic Energy Gel (60 g) contains exactly 22 g of carbohydrates, of which only 0.7 g are sugars. The remainder is maltodextrin – a high-glycaemic-index polysaccharide that is rapidly absorbed and delivers instant energy to working muscles. The energy value per serving is 87 kcal. The gel contains no fat or protein.

The SiS Go Isotonic Energy Gel Variety Pack contains 7 x 60 ml sachets. At the recommended dosage of 1–3 gels per hour of activity, the pack will cover, for example, 2–3 hours of intense endurance training (using 2–3 gels per hour), or up to 7 shorter sessions at a rate of 1 gel per hour. It is also well-suited as a race-day supply for a single marathon or a longer cycling event.

The SiS Go Isotonic Energy Gel Variety Pack 7 x 60 ml contains a mix of different flavours – the exact composition of the variety pack may vary, but it typically includes popular options such as orange, tropical fruit, blackcurrant, apple, lemon, and lime. The orange flavour also contains the natural colouring beta-carotene. The variety pack is ideal for sampling a range of flavours and finding your favourite before committing to a larger single-flavour pack.

SiS Go Isotonic Energy Gel is specifically formulated to minimise digestive discomfort. The isotonic formulation eliminates the need to wash it down with water, reducing the risk of bloating and cramping during exercise. That said, more sensitive individuals may experience 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 dosage.

An isotonic gel, such as SiS Go Isotonic Energy Gel, has the same osmolality as blood, which allows for rapid absorption without the need for water. A hypertonic gel has a higher concentration of sugars – it delivers energy quickly but requires fluid intake for proper absorption; without it, gastric emptying can slow and the risk of digestive discomfort increases. For runners and triathletes, the isotonic variant is far more practical as it does not require coordination with feed stations.

Yes, SiS Go Isotonic Energy Gel can be combined with an isotonic drink. Since the gel does not require water to wash it down, there is no risk of over-hydration. When combining a gel with a drink, keep an eye on your total carbohydrate intake – the recommended maximum for most athletes is 60–90 g of carbohydrates per hour. The gel (22 g of carbohydrates) and a drink can together form a well-balanced fuelling strategy for long endurance efforts.

SiS Go Isotonic Energy Gel stands out from most competing gels primarily due to its isotonic formulation, which does not require washing down with water – an advantage that not all brands offer. The 22 g of carbohydrates per serving is standard within the category. The Variety Pack (7 x 60 ml) allows you to try multiple flavours in one go. When comparing products, it is worth looking at the ingredient list, sugar content, caffeine content, and cost per serving.
