Anatomy of an Energy Gel: What's Really in It?

GU, the world's first energy gel, is one of the most popular sports supplements for endurance athletes. But what's really in it? Here, a decoder to some of the ingredients.


Fruit sugar that gives you an energy kick


Carbs that provide quickly digestible energy to muscles

Potassium Citrate, Sodium Citrate, and Citric Acid

Citrates that neutralize performance-sapping acid buildup in muscles and help turn carbs into energy


Amino acid that works alongside citrates; acts as a buffer against lactic acid buildup


A natural stomach soother


Stimulant shown to increase endurance performance

Leucine, Valine, and Isoleucine

Branched-chain amino acids (BCAAs) that provide fuel and lessen fatigue by limiting the central nervous system's production of serotonin

Vitamins C and E

Antioxidants that help protect muscles from free radicals


Natural anti-inflammatory

Calcium Carbonate

Mineral that helps promote healthy, strong bones

I find energy supplements work for me. At least Go Heads Up is awesome for keeping my energy up through the day and it's all natural stuff. Plus,I find it's a great supplement to boost my energy before a workout.

energy gels are a great way to fuel and boost your workout when you can't carry a sports drink. I found a good alternative to the pasty messy main stream products. Max Energy liquid gel, liquidy and in a clean, recycleable, ready to use pocket flask. And no peanut, gluten, sugar or animal products. Hard to find in stores but go to

I know that they do - you can tell such a difference with them! I am actually now a distributor for Advocare. I use Spark which is a great energy drink, no sugar and full of vitamins. Only has enough caffeine for one cup of coffee! It's great stuff and a bunch of girls at my gym use it. My mom and Aunt swear by it! I am really excited about using it. I have purchased other items at different locations but this one has proven to be the best so far!
