Why Choose?
OUR ORIGINAL AWARD-WINNING ISOTONIC ENERGY GEL
Designed to deliver a quick and convenient supply of great-tasting, easily digestible carbohydrate without the need for water, our GO Energy Isotonic Gel was the world's first and the winner of the Queen's Award for Enterprise. It continues to be a go-to energy source for elite athletes worldwide.
WHY YOU SHOULD USE GO ENERGY ISOTONIC GEL
When you need fast energy, our world-leading GO Energy Isotonic Gel delivers easy-to-digest carbohydrate that can be used as part of your fuelling strategy without the liquid volume that often leaves you feeling bloated and sluggish. The gel also comes in highly practical packaging designed to be easily carried in place of bulky sports bottles.
THE SCIENCE BEHIND GO ISOTONIC ENERGY GEL
Our Performance Solutions team has developed our innovative GO Energy Isotonic Gel formula that enables the stomach to absorb it quickly and turn it into energy fast without the need for additional liquid to dilute it. This in turn enables the rapid replenishment of depleted glycogen stores.
HOW AND WHEN TO USE GO ENERGY ISOTONIC GEL
Each GO Energy Isotonic Gel sachet contains 22 grams of carbohydrate. Depending on your sport or event, you should aim to consume 1-3+ gels every hour to reach a 60g-90g target intake. In some circumstances, such as cold weather, it may be necessary to consume more. Tear off the top of the packaging and squeeze the contents into your mouth as and when required.
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
Our complete product range is developed using a world-class approach to banned substance testing, providing assurance for athletes. For more information on Informed Sport & our unique world class approach, click here.

I love these gels for the consistency. Really easy to consume, especially at the tail end of a long run or race, and they really don’t bother my gut like some other thicker gel products have done.

Great taste and content. The sachet design has always been bad, really difficult to open and too easy to lose the tab, so frustrating to have this distraction on the move and probably easily rectified with an updated design.

Great selection of gels - Fruit Salad flavour is amazing. These have made a big difference to me on long rides - early on and consistently taken and I am able to keep going for much longer and recover better. Also the texture/flavour is great- not overly sweet or thick - requires no extra swigs of water.
