  • World’s first Isotonic Energy Gel
  • For rapid delivery of carbohydrate
  • Improves performance & delays the onset of fatigue

The SiS GO Isotonic Gel was the world’s first isotonic gel effectively delivering an easily digestible and quick supply of carbohydrate for energy during exercise. SiS GO Gels are designed to be consumed without water meaning that you can ensure rapid delivery of carbohydrate to your muscles without the feelings of being bloated that can sometimes occur with over-drinking.


Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. In addition to ensuring optimal carbohydrate stores before exercise, delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue. As such, SiS GO Isotonic Gels represent a highly practical solution to your in-training and competition fuelling strategy by providing you with a quick supply of 20 grams of carbohydrate per gel. Gels can easily be carried in your pocket or your race belt without the requirement for bulky bottles.



Full ingredients

Water, Maltodextrin (from Maize), Natural Flavouring, Gelling Agents (Gellan Gum, Xanthan Gum), Acidity Regulators (Citric Acid, Sodium Citrate), Preservatives (Sodium Benzoate, Potassium Sorbate), Sweetener (Acesulfame K), Sodium Chloride, Antioxidant (Ascorbic Acid), Colour (Beta-Carotene).

Always read the label before use

Advisory Information:

Directions:

Where hydration is also important, SiS GO Isotonic Gels can also be consumed with SiS GO Hydro or with SiS GO Electrolyte to ensure a combination of both energy and fluid delivery during exercise.

trusted and popular energy gel with runners

Verified Purchaser

I have used SiS gels for many years for long distance (half marathon and marathon) running, and never had any issues with upset stomaches (or anything less unsavoury)! The blackcurrant flavour is one of the best, and the gel is a good thickness that doesn't require water but
