Another Satisfied

"I wasn't sure which energy gel to purchase, as there were a ton on the market. After some research I went with e-gel because it didn't have caffeine and it was the best bang for my buck. Man was I thrilled to have it with me on Tough Mudder! We took one every hour or so on our adventure and I didn't once feel fatigued. I can definitely attribute my success on Tough Mudder Tri-State 2011 to the use of e-gel. We killed it and none of my 7 person team were exhausted thanks to the electrolytes and sodium in e-gel."

GU Energy Gel

e-Gel and GU and very similar products with one significant exception - electrolytes!

e-Gel contains 4 times the sodium and double the potassium compared to GU for complete and balanced electrolyte replacement in addition to sustained energy. Both products contain maltodextrin as the primary carbohydrate source with a little bit of fructose. Both products contain amino acids, citrates and antioxidants. You will notice that e-Gel has a thinner consistency than GU so its easier to swallow when you're going hard. Also, each pack of e-Gel contains 50% more energy than a pack of GU making e-Gel more economical.


June 2015 Note:
GU Recently Changed The Formula

The original GU contained 25 grams of carbohydrate and 5 grams of simple sugars for a total of 100 calories of which 20% were simple sugars. Now a pack of GU only contains 22 grams of carbohydrate (still listed as 100 calories??) and they increased the simple sugars to 7 grams for a total of 32% ... so you get less energy but 60% more sugars! That's not a good thing in our opinion (click to see why not). Check out the comparison below ...

Maltodextrin is the preferred carbohydrate source for endurance athletes and as such it is the primary ingredient in e-Gel as well as most other good products on the market. Both e-Gel and GU contain maltodextrin and a little bit of fructose.
e-Gel is the ONLY energy gel that is designed to provide complete and balanced electrolyte replacement that is critical for proper hydration and to avoid muscle cramping. e-Gel has approximately 4  times the amount of sodium and double potassium compared to GU. The sodium and potassium levels in e-Gel are designed to meet the American College of Sports Medicine's recommendation for electrolyte replacement during intense athletic activity.
Amino Acids
The amino acids in e-Gel and GU are designed to reduce lactic acid build up, maintain muscle protein and aid in recovery.
The Citrates in e-Gel and GU assist in the carbohydrate to energy conversion process as well as reduce and slow the build-up of lactic acid in your muscles.
e-Gel and GU are two of the only energy gels that contain antioxidant vitamins C and E to help protect against tissue damage, reduce soreness and aid in the recovery process.
Vitamin B6
e-Gel is the only energy gel to include vitamin B6 which assists in the energy conversion process.
While caffeine may give a temporary mental boost, unfortunately it is a diuretic, meaning that it causes your kidneys to produce more urine - thus promoting dehydration. Proper hydration is critical to optimum performance, and in our opinion caffeine should not be incorporated into your sports nutrition program. Our recommendation has always been that if you feel that you NEED caffeine, then only use a caffeinated product (there are plenty on the market) near the end of your competition when you need the psychological boost the most and there is little time to cause dehydration. We strongly recommend against relying on a caffeinated product for the duration of the competition.

* None of e-Gel's flavors contain caffeine. GU has caffeine in a few of their flavors.
Studies have shown that fat should not be in nutritional products that are consumed during intense athletic activity. As such, all flavors of e-Gel are fat-free. Most flavors of GU are also fat-free with the exception of the Chocolate Outrage and Mint Chocolate flavors.
At retail, a pack of GU cost about 15% less than a pack of e-Gel, however, each pack of e-Gel contains more than 50% more energy than a pack of GU (37 grams vs. 25 grams). On a cost per calorie basis GU is 37% more expensive than e-Gel.



The nutritional information shown above for GU is for a single serving packet of their Vanilla Bean flavor as published February 2015.
