Science in Sport made the world’s first isotonic gel.

SiS GO Isotonic Energy Gels were key in changing the game! They effectively deliver an easily digestible and quick supply of carbohydrates.

The SiS Gel Difference

What does isotonic mean? These gels are equal in osmotic pressure (containing the same number of particles as body fluids) and are less likely to cause stomach distress.

We know taking in carbohydrates with diligence can prevent bonking and improve endurance...but sometimes the high sugar content of gels can cause GI distress. That’s where the isotonic formula comes into play.

These gels 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 or struggle with thick, syrupy gels. They also contain three different electrolytes to aid in the proper absorption of fuel and fluids.

The GO Isotonic Energy Gels are used by some of the world’s top cycling teams.

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

How to use SiS GO Isotonic Energy Gels

These energy gels are easy to consume on long training rides, interval days and races, as they don’t require water to be taken with them.

We recommend having one gel every 20-30 minutes during rides or runs that are over 90 minutes.

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