SIS Energy Gel



What we think

The world's first isotonic gel.

These energy gels by Science in Sport were key in changing the game! They effectively deliver an easily digestible, quick supply of two types of carbohydrate allowing the body to absorb more carbs-per-hour than glucose alone.

What Makes Them Different

They are isotonic, meaning they are essentially equal in osmotic pressure and less likely to lead to stomach distress.

Taking in fast absorbing carbohydrates with diligence can prevent bonking and boost endurance...but sometimes the high sugar content of gels can cause stomach issues. That's where this innovative formula from SiS comes in!

These gels are also unique because they don’t require you to drink water with them, making them a great option if you tend to experience that full, sloshy feeling from drinking too much water with your gels. They also contain three different electrolytes to promote proper fuel and fluid absorption. The consistency of the gels is much more liquid than others, making it very easy to get down during exercise. 

The GO Isotonic Energy Gels are used by some of the top cycling teams in the world. They are designed for on-the-go fuel and are pressure tested so you don’t have to worry about them bursting or tearing during exercise.

They are also Informed Sport Certified, so you know exactly what you’re getting.

How We Use It

These energy gels are portable and easy to take with you on long training rides, especially since they don’t require tons of water to be taken with them. We recommend having one gel every ~30 minutes during rides or runs that are over 90 minutes.

You can also have one with electrolytes 30 minutes before exercise to help with hydration and to top off fuel stores!
