  • The world's first isotonic energy gel
  • 87 calories per serving
  • Delivers an easily digestible and quick supply of carbohydrate

 

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.


  • High carbohydrate
  • Improves performance
  • Requires no additional water or fluid
  • Light, compact, easy-to-carry packaging

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.


  • 22g of carbohydrate
  • Fast-absorbed, easily digestible
  • Truly isotonic formula
  • Delays onset of fatigue

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.


  • Consume directly from packaging
  • Combine with other SiS energy supplements to hit hourly 60-90g carbohydrate intake
Suggested Use
Benefits

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.

FAQs

What is a GO Energy Isotonic Gel?

GO Energy Isotonic Gel is a world renowned convenient isotonic fuelling supplement used by athletes worldwide to maintain optimum carbohydrate levels for increased performance.

What are GO Energy Isotonic Gels made of?

The carbohydrates in GO Energy Isotonic Gels come from maltodextrin (from maize) and provide 87 calories per 60ml sachet. They are stomach-friendly and contain natural flavourings with no artificial sweeteners.

How will GO Energy Isotonic Gel give me more energy?

GO Energy Isotonic Gel quickly delivers 22 grams of carbohydrate in a single serving to help you maintain optimum energy levels and hit the recommended intake of 60-90g per hour during endurance exercise.

How does Science in Sport GO Energy Isotonic Gel fit into my overall fuelling plan?

As an athlete of any sport or a specialised endurance athlete, our GO Energy Isotonic Gel can be used on its own to fulfil your fuelling requirements or combined with other products from our extensive range of energy supplements.

When should I consume GO Energy Isotonic Gels?

You should consume GO Energy Isotonic Gels one to three times per hour during endurance exercise to maximise carbohydrate utilisation rates. Alternatively, take one halfway through high intensity exercise (such as football or rugby) to rapidly replenish glycogen stores.

Is GO Energy Isotonic Gel isotonic?

Yes. In fact, SiS GO Energy Isotonic Gel was the world's first truly isotonic energy gel.

What makes GO Energy Isotonic Gel better than eating regular foods such as a banana, for example?

GO Energy Isotonic Gels are designed to be absorbed fast into your gut for fast energy, whereas some solid foods take longer to digest because they have more fat and fibre and can cause bloating and discomfort during exercise.

Should I add water to GO Energy Isotonic Gel?

No. GO Energy Isotonic Gel is designed as a convenient energy source that doesn't require additional water or fluid. Just simply squeeze the contents from the sachet directly into your mouth.

Does the Science in Sport GO Energy Isotonic Gel range use natural flavourings?

Yes. Our GO Energy Isotonic Gel range of carbohydrate supplements use only natural flavours and are free from colours and preservatives.

Will GO Energy Isotonic Gels fit in my cycle jersey pockets?

Yes! All GO Energy Isotonic Gels are lightweight, compact and designed to fit in jersey pockets, cycle bags and waist packs. What's more they're pressure-tested so you don't have to worry about them leaking or the packaging tearing or bursting during exercise.

Has Science in Sport GO Energy Isotonic Gel been tested for banned substances?

Absolutely. Like all of our sports supplements, GO Energy Isotonic Gel is tested under the Informed Sport programme and does not contain any banned substance. Informed Sport is a global quality assurance and supplement certification programme for sports supplements.

Good choice of flavours, but not been using the product long enough to fully know if it has improved performance to any degree of significance. On the face of it, it does seem so, but I am reviewing the post game data from the performance tracking devices in use.

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.
