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 in to 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 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.

SiS GO Energy + Electrolyte Gel – Salted Strawberry | Individual

$1.99
The SiS GO Energy + Electrolyte gel builds on the established science of the SiS GO Isotonic Energy gel, the world’s first and only truly isotonic energy gel.

What makes them so special?

This product not only delivers a rapid-absorbing supply of easily digestible carbohydrates (22 grams), but also provides 130mg sodium, 9.5mg potassium and 1.5mg magnesium per gel. Electrolytes including sodium, potassium and magnesium are lost through sweat and need to be replaced in order to help the body maintain fluid balance, alongside an appropriate fluid intake. The electrolyte bump make them great for summer month training when the strain on fluid balance is higher. Not to mention, these are Informed Sport Certified so they are trusted by even the most elite of athletes. They have: Lemon and Mint, Salted Strawberry, and Raspberry. Single serving or batches of 30!

What's in it?

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 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.

SiS Beta Fuel Gel – Strawberry & Lime | Individual

$2.50
SiS Beta Fuel Gel is a game changing gel made with a 1:0.8 Maltodextrin:Fructose ratio, providing 40g of carbohydrates. The science behind this new ratio is genius! If you haven’t taken a guess yet, it is actually formulated to reduce symptoms of stomach fullness and stomach upset. On top of that, this gel provides 30-50% more carbohydrates than most of the other sports gels! New technology like that allows athletes to compete at their full potential without distractions or discomfort. How did SiS manage to pull this off? Science In Sports created a neutral pH, isotonic solution that allows the intestines to absorb the gel contents at an appropriate rate without drawing water into the intestines. Usually that water is what causes an upset stomach, especially with super sugary sports gels. Hence their brand name, Science In Sports! What're the options? Now, not only did they master the science behind gel products, but they also made sure it was yummy for consumption! SiS Beta Fuel Gel comes in two flavors: Orange and Strawberry & Lime. Guess what else? They have a mild Neutral flavor now for those wanting to keep it simple.
