Isotonic Science in Sport Gels

Our SiS energy product range includes their best offerings, with a wide variety of SiS energy gels to choose from. Each sachet contains isotonic carbohydrates, which have the benefit of being able to be consumed without additional water, unlike some other energy gels. This makes them fast and easy to digest, ideal for athletes who are looking for convenience and want to avoid carrying a water bottle.

TORQ Energy Bars and Much More

In addition to their energy gels, you can find other products to provide the nutrition you need for intense activities. Their energy bake bars are similarly lightweight to their gels and contain an optimal balance of carbohydrates and fructose to provide you with a boost when you need it most. Their effervescent electrolyte tablets are also a great choice for optimal hydration, helping to restore key minerals and vitamins lost through sweat.

If you have any questions about Science in Sport gels or any of their other energy products, be sure to get in touch with us. A member of our team will be more than happy to help you.
