Product Description
SiS gels are 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 and quick supply of carbohydrate.
The SiS Gel Difference
What does isotonic mean? They are equal in osmotic pressure (same number of particles in solution as your blood) and are less likely to lead to 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 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 proper fuel + fluid absorption.
The SiS GO Isotonic Energy Gels are used by some of the top cycling teams in the world.
They are also Informed Sport Certified, so you know exactly what you’re getting is safe.
How to use SiS 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 to top off fuel stores!
The pros have long trusted SiS. You can too.
