SiS GO Isotonic Energy Gel Variety Pack

Get your hands on a variety of 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 two types of carbohydrate, allowing the body to absorb more carbs-per-hour than glucose alone.

The SiS Difference:

What does isotonic mean? They are essentially equal in osmotic pressure and 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.  

What you get in the SiS Gel Variety Pack:

6 total gels in the best-selling flavors!

• 3 x Lemon and Lime
• 1 x Tropical
• 1 x Orange
• 1 x Apple

How to use the SiS Bundle:

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!
