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.

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.

Loving these gels. This is the first gel that is easy to take while doing an activity. You don't have to struggle to make sure you get all of the gel and you don't waste half a bottle trying to wash it down. Much smoother than other gels that are like trying to eat peanut butter. And the taste is spot on.

Chris Uber


Best flavor I've tried so far!



I haven’t found a better energy gel that sits so well in my stomach. I can down the entire thing without hesitation.



The best for long runs, you don’t need add water and the flavor is really good

SINDY Almaraz


Amazing gels, basically instant energy, taste great, easy on tummy.

Eric Hanson


Love this product for the simple reason it goes down easy. It’s not thick and gooey like all other gels I’ve tried and you can take it without water which is nice. I bought the cherry without the caffeine and I love it



All I can say is wow. Great flavors with not aftertaste and from a performance standpoint, all my buddies ask what I am using for energy because the improvement is noticeable.



Better than Gu, goes down fast without a sticky mess. Worked well in my last century ride



This is a great product - the benefit is almost instant - right now I’m looking for something that’s more like a power bar - the trouble with bars is that they’re hard to get down - too much chewing and too sweet, so your mouth is full of sugar for an hour - if only there was something in between a gel and a bar that was more substantial, but easier to chow down on....



Great fuel, easy to use and fast results

Mark Ferguson


I really like these gels as they are easily digested and do not need to be taken with water; my only negative is that I bought a "bulk" pack and they have an exp. date of 02/19. I wish these would last a little longer.



Great product. Great flavor. I use them for very exercise

Cameron Paterson


These gels are the best on the market. Not only do they taste good, they provide the needed energy without destroying your gut.

Anders Dybdahl


Love the taste! Easy and compact for running packs!



Gels are excellent and work for training easy on the stomach

Daniel Corredor


These do the trick. I’m a big fan of this product.

Chris Hepburn


I have used these several times to prevent from bonking. These gels have always occupied a cycling jersey pocket on all of my rides for a quick energy boost.

Hieu Nguyen


The tropical flavor is great. The gels provided a boost and are easy to carry.

Great and easy to use. These work great along with the electrolyte and caffeine gels.

Yuriy Bubnov


Love the taste of the gels and the energy they provide for a long run. The only reason these aren't 5 stars is that the size of the gels don't always fit well into water bottle pouches or gel holders. These are slightly larger in height so I find I can't carry as many as I want.

Todd W


Not too sweet! Works quickly

Susan Witter

James Woodward
