Science in Sport GO Isotonic Energy Gels give you 22 g of carbohydrate from maltodextrin in each 60 mL gel. The isotonic formula means you can take them without extra water, which suits runners, cyclists and anyone fuelling during long or hard sessions. Each gel has 368 kJ (87 kcal), and flavours include Apple, Blackcurrant, Fruit Salad, Lemon & Lime, Orange, Pineapple and Tropical.
Key features
- 22 g carbohydrate per 60 mL gel, from maltodextrin
- Isotonic, so no extra water is needed
- 368 kJ (87 kcal) per gel, with 0.6 g sugars and no fat or protein (Orange)
- Sweetened with acesulfame K
- Single-serve 60 mL gel that is easy to carry
Nutrition information

Ingredients
Orange: Water, Maltodextrin (33%), Flavouring, Gelling Agents (Gellan Gum, Xanthan Gum), Acidity Regulators (Citric Acid, Sodium Citrate), Preservatives (Sodium Benzoate, Potassium Sorbate), Sweetener (Acesulfame K), Sodium Chloride, Antioxidant (Ascorbic Acid).
How to use
Depending on your sport or event, SiS suggests 1 to 3 or more gels per hour to reach 60 to 90 g of carbohydrate per hour. No water is needed. Use them before and during long runs, rides or races.
Good to know
- Contains a sweetener (acesulfame K).
- At 36 g of carbohydrate per 100 mL, these gels are less concentrated than the 65 to 75 g per 100 mL the Australian Institute of Sport describes for typical sports gels, which is why they are isotonic.
- If symptoms persist, consult your healthcare professional.
FAQs
Do I need water with GO Isotonic gels?
No. The gels are isotonic, so SiS designed them to be taken without extra water. Each gel has 36 g of carbohydrate per 100 mL, lower than the 65 to 75 g per 100 mL the Australian Institute of Sport describes for typical sports gels.
How many gels per hour should I take?
SiS suggests 1 to 3 or more gels per hour, depending on your sport or event, to reach 60 to 90 g of carbohydrate per hour. At 22 g each, three gels give 66 g. Practise your fuelling in training before you rely on it in a race.
How much energy is in one gel?
Each 60 mL Orange gel has 368 kJ (87 kcal), 22 g of carbohydrate, 0.6 g of sugars and no fat or protein. Values vary slightly between flavours, so check the pack.
Can I use them with the caffeine or electrolyte gels?
Yes. For sessions over 90 minutes, SiS suggests one GO Energy + Electrolyte gel with two GO Isotonic gels per hour. The GO Energy + Caffeine gels add 75 mg or 150 mg of caffeine. See all running gels.
