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.
Awards
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.
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.

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 Immune?
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 Energy products e.g 1 x GO Isotonic Energy Gel and 1 x 500ml 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'?
GO Isotonic gels contain natural flavourings.
Why are these better than regular foods, for example a banana?
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, Gels do not contain aspartame.
Will they fit in my cycle jersey pocket?
Yes! All 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.
As above great help when strength is getting low

Personal preference if you like these or not. I’ve found I can open and eat these while cycling. The packaging allows you to pierce a hole, then you can squeeze all the gel out and the finished wrapper can go in your back pocket. A nice energy boost for mid-ride, keep a few in your pocket... They taste good.

Simon Thompson

These gels are great and I have no problem with the flavours or how they help me perform when I'm training or racing. I can only give 3 stars for them as I have a terrible success rate with opening them! This can be infuriating when on a long run and I really need the top up or especially in a race. So many times I've only been able to tear them a tiny bit then the rest of the gel refuses to come away easily. That includes trying to rip it open with my teeth! Wish they were more reliable.

These are great. I was using another product which I liked but this one is better because its not too sweet and sticky. The other product I was using was very sticky I guess it has more sugar in it not good if you get it on your hands and gloves. The SIS gel is really easy to digest and this flavour is not sickly. I will be using this one in future I really like it.
