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.

Truly isotonic formulation - no need for water
22 grams of rapidly absorbed carbohydrate per gel
Convenient easy-to-take format
Contents: 6 x 60ml gels per pack
Flavoured Maltodextrin gel with added sweetener.

Recommended Usage:

Consume 1-3 gels per hour to deliver approximately 60 grams of carbohydrate and maximize carbohydrate utilization rates. 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.

Directions for Use:

Simply tear off the top of the packaging and consume - there is no need to mix with water.


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.

Suitable For: Vegans, Vegetarians, Lactose-free, Gluten-Free, Wheat-Free, Nut-Free, Soy-Free


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.

Best energy gels

I've been using SiS gels for a few months now and find them palatable and easy on the gut. Great energy boost on long runs. I like the texture, the fact that you don't need to consume them with water and the flavour range is really good. Favourite flavours: apple, orange and blackcurrant.

Great gels

These gels are delicious, and gentle on your stomach. Don’t need to be consumed with water either which is a bonus!
Sportsfuel were great to order them through and they arrived a couple of days after I ordered them online.

SIS - best brand

SIS really know their stuff and these gels are no exception. They are easy to digest, perfect serving size, no need for water with them & they pack a punch. I always carry 2 or 3 on my longer rides

1st time gal try

My husband is traing for some half marathon events, sub 1.30hr. He tried a gel this morning for the first time. Loved it! He said it sat well in his gut, tasted great, apple flavour. He took it the 10km mark , so half way. He didnt notice an instant energy rush, but felt good running and felt good for rest if the day 😊

First time gel user

I’ve never used gels before but need nutrition on my longer training runs. These are great. Mild taste, easy on the stomach. Will continue to use.
