What we think

When your body's muscle glycogen (carbohydrate stores) run out, you can experience that hit the wall feeling known as bonking. For those long rides and runs, your muscle glycogen will get used up and, unless you replenish it, you will start to see a decrease in performance. Taking in fast absorbing carbohydrates will prevent bonking and boost endurance, but sometimes the high sugar content of gels can cause stomach issues. That's where this innovative formula from SiS comes in!

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. They are isotonic, meaning they are super concentrated and are less likely to lead t stomach distress.

These gels are also unique because they 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. They also contain three different electrolytes to promote proper fuel and fluid absorption. The consistency of the gels is much more liquid than some, making it very easy to get down during exercise. 

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. We recommend having one gel every 30-45 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!

I recommend this product

Has acesulfame in it

Tastes okay and i like the isotonic aspect but has an artificial sweetener. I'm intolerant to it, sadly.

Better than gels

Easier to take and absorb than gels. Only downside is they are not as calorie dense as gels. Taste is OK.

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.
