SiS GO Energy + Caffeine Gels

The original GO Energy Gels by Science in Sport – but with a kick.

In case you don’t know, the GO was key in changing the game. They effectively deliver an easily digestible and quick supply of carbohydrate.

The SiS Caffeine Gel is based on the same formula as the innovative SiS GO Isotonic Energy Gel BUT with the addition of 75mg (or 150mg!) of caffeine. Fast energy with a mental and physical boost.

Unlike the lingering caffeine taste from most products, the GO Energy + Caffeine is clean in the mouth and easy to digest.

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.

The Caffeine Benefit:

Caffeine acts centrally on the brain to lower the perception of effort, which is particularly noticeable in longer events. In hard training and events over 90 minutes, mental fatigue plays a big role as things progress, in addition to physical.

How to Use SiS Caffeine 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, runs, or events that are over 90 minutes – but space them out with other gels/fuel to spread the caffeine out.
