Product Overview

About GO Isotonic Energy Gel

The GO Isotonic Energy Gel was the world's first isotonic gel effectively delivering an easily digestible and quick supply of carbohydrate for energy during exercise.

They are designed to be consumed without water, minimising the risk of being bloated that can sometimes occur with over-drinking.

Provides you with 22 grams of carbohydrate per gel.


Winner of the Queens award for enterprise, this innovative product continues to be seen at the forefront by endurance athletes. Use during endurance sessions and events to help avoid flagging.

Suggested Use

Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. Delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue.

The Isotonic formula allows the gel to empty from the stomach quickly as no fluid needs to be drawn into your stomach to dilute the gel, providing fast energy. SiS GO Isotonic Energy Gels are highly practical and can easily be carried without the requirement for bulky bottles.

Informed Sport Registered

When should I consume these?

Consume 1-3 gels per hour during endurance exercise to maximise carbohydrate utilisation rates. Alternatively, take one halfway through repeated high intensity exercise (such as football or rugby) to rapidly replenish glycogen stores.


When should I have these versus Electrolyte, Caffeine or L-Carnitine gels?

These should be consumed when you need a fast, convenient energy boost. During endurance exercise lasting over 90 minutes, these should be the main gels that are used throughout a race. Use in combination with other SiS Energy products e.g 1 x SiS GO Isotonic Energy Gel and 1 x 500ml SiS GO Electrolyte to hit 58 grams of carbohydrate (per hour).


Is this gel Isotonic?

Yes, this gel was the first truly isotonic energy gel.


Are these 'natural'?

SiS GO Isotonic gels contain natural flavourings.


Why are these better than regular foods, for example a banana?

SiS GO Isotonic Energy Gels are designed to be absorbed fast into your gut, providing fast energy. Some solid foods can take a while to digest as there's more fat and fibre in whole foods, which during exercise can cause feelings of bloating and discomfort.


Do these contain aspartame?

No, SiS Gels do not contain aspartame.


Will they fit in my cycle jersey pocket?

Yes! All SiS GO Gels are lightweight, compact and designed to fit in jersey pockets, cycle bags and waist packs. They are pressure tested, so don't worry about the packaging tearing or bursting during exercise.

Prodotto di ottima qualità

Utilizzo da anni, per me sono il top



A good selection of flavours in the box, it has vanilla, I have not been able to purchase this flavour on its own. Was good value, this product is ideal for having on marathons and long training run's as it saves calling someone out to do a fluids drop-off. The only downside is opening them with damp hand's, end up using teeth, a larger 'top' to get hold of would be good. Have purchased these for year's and highly recommend them.



Confezione con gel di tutti i gusti
