What we think

As the world's first isotonic gel, these Energy Gels by Science in Sport are changing the game! They effectively deliver an easily digestible and quick supply of carbohydrate for energy during exercise by combining sources of carbohydrates, allowing the body to absorb more carbohydrates per hour than glucose alone. These gels are unique because they don’t require you to drink water with them, making them a great option if you tend to experience that full feeling from drinking too much water with your gels. They also contain three different electrolytes to promote proper fuel and fluid absorption.

The GO Isotonic Energy Gels are used by some of the top cycling teams in the world. They are designed for on-the-go fuel and are pressure tested so you don’t have to worry about them bursting or tearing during exercise. They are also Informed Sport Certified, so you know exactly what you’re getting.

How We Use It

These energy gels are portable and easy to take with you on long training rides, especially since they don’t require tons of water to be taken with them. SIS recommends consuming one gel per hour for exercise lasting longer than 90 minutes. They can also be consumed used before exercise to make sure electrolytes are available for fluid absorption. Try the caffeinated flavors if you are looking for that extra kick!

SIS Energy Gel

These gels work for me better than solid food bars when I bike over two hours. Just open, squeeze and swallow. Done. I enjoy the apple taste, so that really helps. I always carry one just in case I feel the need for some energy when I am not at my best. They also come in handy for recovery after a ride to restore some carbs.

Will not upset your stomach

I'd had problems running long distances and maintaining a good nutrition because either my stomach complained or avoided taking as many gels are necessary. However with SIS, I don't get an upset stomach while I can eat with the necessary performance to keep a good pace for long distance runs.

Works Fast

I found SIS of all places at the Tour Down Under a couple of years ago and fell in love with it. It is must faster into the system and you do not feel like you need to drink ASAP. I love the Cherry flavor, Mango is decent as well.

Pretty good

Packaging can be tough to open, and they should remove the sodium benzoate... not good for you
