Science in Sport Isotonic Gel Review

Disclaimer: I received Science in Sport Isotonic Gels to review as part of being a BibRave Pro. Learn more about becoming a BibRave Pro (ambassador), and check out BibRave.com to review, find, and write race reviews!

It’s funny, during ultras I’m the girl you jealously watch as she pigs out on literally anything and everything (sans gluten) at the aid station.. But soon as you give me special fuel designed to be eaten while running my stomach is begging to go back to potato chips and m&m’s. I have tried a decent amount of different gels at this point with varying success, but after recently trying out SiS I have to say they are quite different from most others in all the best ways!

Consistency

I really like that SiS gels are so thin you can just squeeze and swallow. No chewing, worrying about it being stuck in your teeth/throat, or having to wash them down with water. During my hike, I was wishing I had brought a flavored drink (water was getting old) and I was able to take a gel as a replacement. I also used SiS during the Savage Race OCR and it was awesome they were thin enough that I could pour them into my mouth so I didn’t have to stick my mouth on the package that was covered in dirt from the race.

I wanted to demonstrate how different their consistency is myself, but I am no video maker and found they actually already had a video that shows it perfectly!

Flavor

Their flavors do a really good job of not being nearly as in your face as most gels. They also seem to leave way less aftertaste, if they do at all. I LOVE the apple. I am not generally someone for super sweet gels, leaning toward more savory ones like PB, but do have times when I want sweet stuff. I have yet to find a time when the apple’s flavor wasn’t appealing to me though. I also feel like that flavor leaves literally no aftertaste. I was very surprised by the lemon & mint being so good. It had a very soothing feel to me, like it would be good for an upset stomach. Salted strawberry was also good, but not apple status, and possibly better for sweeter times. I personally didn’t like the double espresso, but I also don’t really like any form of normal coffee (I know, BLASPHEMY! 😱).

Packaging

The packaging is a decent amount larger than most gels but it still fits in all of my gear pockets meant for gels. Also even though you are “eating” more, I find it much easier to eat more of SiS than less of other gels due to the consistency and taste. The part about the packaging I really like is the shape of their top. For me it is MUCH easier to open. My hands get really slippery with sweat and I have actually had times where my fuel plan went out the window with other products because I couldn’t manage to open the package.

SiS gels are so different from others that if you thought gels weren’t for you, but are still looking for a fuel source I would definitely recommend giving them a try!
