Gels Are My Jam
I’m totally Type-A when it comes to nutrition on the run. I’m a faithful gel-taker every four miles on long runs or during races. I’ve been told before that I don’t need to take in that many carbs/sugars, but it has worked for me thus far, and I’ve never hit the dreaded “wall” during a marathon. So take THAT, gel haters!
I was wicked excited to try these Science In Sport energy gels, because I was intrigued with the packaging, flavors, and claims of not needing to drink water with the isotonic variety.
I received a boatload of product, which will definitely last me through my summer training. Science In Sport sent four flavors:
- Energy + Electrolyte Lemon & Mint
- Energy + Electrolyte Salted Strawberry
- Isotonic Energy Apple
- Energy + Caffeine Double Espresso
Energy + Electrolytes
According to the Science In Sport site, this variety of gel not only delivers a rapid supply of easily digestible carbohydrates (22 grams) for energy, but also provides 118 mg sodium, 9.5 mg potassium and 1.5 mg magnesium per gel. The Lemon & Mint and Salted Strawberry will definitely be my main staple gels this summer. Check out my first impression videos below for what I think of each!
Energy + Caffeine
This gel speaks my love language! I’m a huge coffee lover and probably drink four to five cups a day. The 150 mg of caffeine in the Double Espresso flavor provides a high dose for high-intensity races and long, tough days on the road. There’s more caffeine per ounce than a cup of Death Wish coffee! I would suggest this gel if you need an extra boost of energy. (I’m thinking early-morning runs or even late-night treadmill slogs.)
What Does Isotonic Mean?
So, what in the world does isotonic mean? According to the Science In Sport website, its Isotonic Energy Gel is the world’s first to effectively delivering an easily digestible and quick supply of carbohydrates for energy during exercise. They are designed to be consumed without water, minimizing the risk of being bloated that can sometimes occur with over-drinking. Each packet provides you with 22 grams of carbohydrates.
Y’all, I drink so. much. water during my summer runs. So much so that the water sloshes around in my stomach, and I rue the day water was created. The thought of not washing down a gel with water seemed absurd to me. It’s just what I did whenever I took one. Hasta la vista, agua!
