Science in Sport (SIS) energy gels- Product Review and GIVEAWAY

At the end of this review, look for a chance to win a free pack SIS Energy Gels. 

I have never been a big fan of gels.  I have a weak stomach and haven’t had a lot of luck with keeping them in.  When we received the opportunity to try out Science in Sport(SIS) energy gels, I was super exited to try out the products. The SIS gels are designed to be more easily digestible. Which is a huge selling point to me.

SIS hooked me up with a heavy load of Gels. Enough for my training cycle and extras to share on group runs. I can’t wait to see how much they enjoy them! I received 3 different variations of the gels in 4 different flavors; energy+electrolytes (Salted Strawberry & Lemon & Mint flavors) , energy+caffeine (Double Espresso Flavor)  and Isotonic Energy (Apple Flavor). 

I taste tested all the flavors before the run and thought they all tasted good.  My favorite flavors were the Apple and Salted Strawberry. The double espresso was more palatable during my first taste test, but I didn’t enjoy it as much when I tried it during my run.  I am more picky when I run, for some reason.  

The packets are a bit larger than your typical gels but they aren’t huge or obtrusive.  They easily fit in my zipper pockets and flip belt.  I only carry one gel at a time, and I found I had plenty of room.


My favorite flavor was the salted strawberry, it was similar to liquidy jello consistency and tasted good on a hot summer run.  My favorite product was the Isotonic Energy gel (Apple Flavor). It’s consistency was almost like a watery applesauce, not quite as thick.  Isotonic gels are not only designed to be more easily digestible, but they are also designed to be safely taken without water.  I really think this will help me avoid the nausea and bloating I have experienced in previous training cycles.

I would definitely recommend trying the SIS gels if you have stomach issues on the run.  Getting your nutrition right before race day in an important component to your race day strategy.
