e-Gel vs Roctane energy gel comparison

Roctane is GU’s premium energy gel, and when you compare it to e-Gel we’re confident that e-Gel is still the best performing product. e-Gel has more complex carbs and less sugar than Roctane which allows for increased energy uptake. e-Gel puts all the electrolytes you need right in the gel to avoid cramping and injuries. e-Gel is also a thinner consistency so it’s easier to get down, no more chocking on thick energy gels! That’s not all, read below for a complete comparison.

Each pack of e-Gel provides 50% more energy than a pack of Roctane. This makes e-Gel more economical because 2 packs of e-Gel is the energy equivalent to 3 packs of Roctane. Fewer packs to carry and less trash to deal with, that’s a good thing!

e-Gel has more complex carbs than any other energy gel and this is critical because your body can uptake more energy when you use complex carbs instead of simple sugars.

How is this possible?

Read on (or watch this video)

The carbs/energy in an energy gel are transported into your cellular system through osmosis. If you recall learning about osmosis in science class, it’s the way a fluid crosses a membrane. In order for the fluid to cross, it has to be an equal or lower concentration than the fluid on the other side of the membrane. In this case you’re trying to get the gel across your cellular membrane so you can use the energy. Gels by themselves are extremely concentrated (hypertonic), that’s why you need to use water with gel so that you can lower the concentration until it becomes isotonic (the same concentration as your cellular fluids). When you do, the gel and water get absorbed – osmosis!!

What’s interesting is that the concentration of a fluid (also called the osmolality) is largely dependent on the NUMBER of particles in the fluid, and less dependent on the size of the particles. Complex carbs by definition have a larger molecular structure than simple sugars, basically they have more glucose molecules stuck together. But remember, it’s the number of particles, not the size that matters most. What that means is that at the point of absorption (isotonic), a fluid with complex carbs can transport nearly twice as much energy into the cellular system compared to one with simple sugars.

This isn’t something that we’ve invented here a Crank Sports, it’s proven science. Many energy gels (including e-Gel) use at least some maltodextrin for this reason. Maltodextrin is a complex carbohydrate with an extremely large molecular structure. Where e-Gel sets itself apart from other products is that we use much more complex carb and less sugar. This allows you to get more energy when you use e-Gel compared to our competitors. Why do other companies use so much sugar? Simple, because it’s sweet and inexpensive, and sweet things sell. So if you want to sell a lot of something you make it sweet. But if you want to make the best PERFORMING product you use complex carbs.

sugar

e-Gel

18%

Roctane

29%

By providing lower sugar and more complex carbs instead, e-Gel is able to provide significantly more total energy uptake. See our complex carb discussion for complete details.

carb sources

e-Gel

Maltodextrin
Fructose

Roctane

Maltodextrin
Fructose

Both e-Gel and Roctane use a combination of maltodextrin and fructose. Maltodextrin is the preferred complex carbohydrate for endurance athletes and fructose is in the product because it allows for additional energy uptake that you do not get from gels that don’t use it, read why

sodium

e-Gel

230 mg

Roctane

125 mg

e-Gel is the only energy gel to provide complete electrolyte replacement in the gel – where it should be! The most important electrolyte that you need to replenish is sodium to help you maintain hydration and to avoid cramping and injuries.

For a more detailed discussion of why it’s important to have this level of electrolytes in the gel instead of getting your electrolytes some other way:

potassium

e-Gel

85 mg

Roctane

unspecified

Potassium is the other electrolyte that is important to replace during your training and competition, along with sodium. Roctane contains potassium citrate but the company does not specify on the packaging how much potassium is in Roctane. The level of potassium in e-Gel is designed to meet the American College of Sports Medicine’s recommendation for replacement during athletic activity. See the sodium discussion for additional details.

amino acids

e-Gel

Histidine, Leucine,
Valine, Isoleucine

Roctane

Leucine, Valine,
Alanine, Isoleucine

Both e-Gel and Roctane provides a blend of 4 important amino acids. Amino acids help to reduce lactic acid build up, reduce soreness, maintain muscle protein and aid in quicker recovery.

Roctane also includes Taurine which is often referred to as an amino acid, but it is not. Amino acids are protein building blocks, while Taurine is an amino sulfuric acid. Taurine is also a diuretic, meaning that it can cause increased urine production and dehydration. We do not use Taurine in e-Gel or any of our products. 

antioxidants

e-Gel

vitamin C 120%
vitamin E 120%

Roctane

none specified

Antioxidant vitamins C and E help protect against tissue damage, reduce soreness and aid in the recovery process.

citrates

e-Gel

Sodium Citrate, Potassium
Citrate and Citric Acid

Roctane

Sodium Citrate, Potassium
Citrate and Citric Acid

Citrates assist in the carbohydrate to energy conversion process as well as slow the build up of lactic acid in your muscles.

"Figuring out how to stay hydrated, not get upset stomach and prevent muscle cramps during long runs and races has been one of my biggest challenges. In the past my muscles would ache and twitch and cause me a lot of pain after long runs. I came across e-Gel energy gels this summer used them during the Top Of Utah Marathon, took 17 minutes off my previous marathon PR and easily qualified for Boston." ...

"This is by far the best energy gel product on the market, and I have been through them all. I have had nothing but positive training and racing experiences with this product. I trained on and used e-Gel in a half half marathon and busted a 1:32.44! My personal best of 5 half marathons. The sustained energy is incredible! I absolutely love this product." ...

"40 miles into a 56 mile ride in the desert with two big hills I started cramping, and had to stop several times. The next week I did the same ride with e-Gel and had no cramping despite it being over 100 degrees. My hydration was the same, so I have little doubt the e-Gel played a big part in keeping me going that day." ...

"I recently completed a half-iron distance triathlon with a brutal bike course. At the end of the ride my quads started to cramp. I nursed an e-Gel over the first mile of the run and the cramps abated. I thought it may have been coincidence, but when the cramps resurfaced at mile 7 only to resolve with another e-Gel I was sold. I only drank water on the run and took e-Gel, so I feel confident that this product made the difference. " ...

"I used e-Gels exclusively and exactly as directed in training for the Lakefront Marathon. This was my fourth marathon and I did not expect to PR, but just to complete it well. With the help of e-Gels taken at miles 2, 7, 13, 18, and 23, I took 10 minutes off of my marathon time and never hit the 'wall' or cramped as I had done in previous events. Some guy laughed at me at the start asking why I had so many energy gels. I told him I had a plan and I was sticking to it. I'm pretty sure I passed him somewhere around mile 22." ...

"I was running my best marathon ever in Detroit, had five miles to go and I took my e-Gel 100 yards before a water station. I got to the station and it was a bunch of guys handing out beer! GU and other energy gels are so thick that I would have needed water right away, but the e-Gel was so thin and easy to digest, I got through it just fine when I hit a water station about a mile later. Not only did I finally hit my sub-three hour dream, I hit 2:57!" ...

"I am an on-ice official in the AHL and I want to share my story about e-Gel ... My job as linesman requires me to sprint repeatedly and physically separate anyone who fights throughout the game. We get no breaks, no downtime, no relaxing...I need my energy level to remain constant. I had yet to find any product that satisfied my requirement. I tried GU, Clif Shots and other energy gels, but found that I was still needing something to get me thru the last half of the game. With e-Gel, I found it." ...
