SiS Go Isotonic Energy Gels

The world’s first isotonic gel.

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

The SiS Difference:

What does isotonic mean? The SiS Go Energy Gels are formulated to match the osmotic pressure of 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 stomach issues. 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 the 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 proper fuel + fluid absorption.  

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 portable and easy to take with you on long training rides, interval days, and races, especially since they don’t require tons of 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 with electrolytes 30 minutes before exercise to help with hydration and replenish fuel stores.
