GU Energy Gel

GU provides athletes with a shot of 100 calories in the form of a patented carbohydrate blend (70%-80% maltodextrin and 30-20% fructose) to deliver high-quality, easily-digested and long-lasting energy for athletes in every sport and at all levels. GU also includes electrolytes to ensure proper hydration, an antioxidant blend to stave off muscle tissue damage and an amino acid blend to delay muscle fatigue.

Everything inside each packet of GU is engineered to do one simple thing: provide your body with the essential requirements it needs to keep going for miles and miles and hours and hours. It goes down easy, and it goes to work fast so you don't have to slow down.

Usage

Both GU Energy Gel and our new Roctane Ultra Endurance Energy Gel pack 100 calories into every packet. 100 calories is an ideal serving size to suck down 15 minutes before training or racing in order to top off your electrolyte and glucose stores, followed by one every 30-45 minutes along the way, washed down with a few sips of fluid.

For optimum results, always drink at least 24-30 ounces of fluid per hour during training and racing. Exact GU intake depends on the intensity of your pursuit and your body weight and fitness level. The fitter you are and the more efficient your metabolism, the more GU you can eat each hour, up to approximately 340 calories every 60 minutes.

Combine GU with Roctane Ultra Endurance Gel, GU Electrolyte Brew and GU Recovery Brew for the ultimate in sports hydration, fueling and recovery. Take one gel 15 minutes before training or competition and then one gel every 30-45 minutes during exercise. Drink Electrolyte Brew throughout your training or racing, and drink Recovery Brew within 30 minutes after you’ve stopped.

FAQ

There are only 100 calories per packet, yet I burn through 100 calories in 10 minutes. Shouldn’t I eat more than one every 30-45 minutes?

We limited GU to 100 calories because, in general, the body can digest roughly 350 calories per hour during exercise. If you tried to eat more, the body would divert blood from your muscles— say “buh-bye” to a personal record—to handle the excess food. If your metabolism is slow, then one GU every 45 minutes works fine. If you have an athlete’s metabolism, try ingesting one GU every 30 minutes and see if it agrees with you.

How do you eat GU?

Rip open the top and squeeze the entire packet into your mouth—don’t save half of it for later. GU’s recipe of carbohydrates and amino acids was created to be taken in one shot to provide you with maximum benefits.

How should you use GU to help you recover from hard training or racing?

When you stop, go ahead and eat a pack of GU, even if it’s been less than 30 minutes from your last GU shot. Now that you’ve stopped exercising, your stomach can handle those calories and needs them to start restoring your muscle glycogen—essentially the body’s instant fuel reservoirs.

Can I use GU for a strength workout or even yoga?

Sure. While GU was designed for endurance sports, it can be used anytime you need energy to fuel a workout. It can also serve as a 100-calorie pick-me-up if you’re dragging or simply need a snack to carry you through until your next meal.

How does the caffeine in GU help me?

GU energy gel comes in both caffeinated and non-caffeinated flavors. Strawberry Banana and Lemon Lime do not have any caffeine in them. Orange, Vanilla, Chocolate, Triberry and Plain all have 20mg of caffeine per packet. GU’s Espresso Love flavor has 40mg of caffeine. Caffeine consumption during exercise improves performance in several ways: it sharpens focus and perks you up; but more importantly, it helps the body produce more power, reduce the pain of hard efforts, and may even tap fat for fuel during exercise. All of this prolongs your ability to exercise at a high intensity. We use just enough caffeine to jump start this benefit and no more.

Does GU freeze?

Yes, but well below zero. It does thicken in cold weather, so keep GU close to your body to keep it warm.

How long does GU take to work?

The fructose converts quickly into an energy molecule that your muscles can tap within minutes. The maltodextrin, which makes up 70-80% of the carbohydrate blend (depending on flavor), takes several minutes longer. Because of this delay, your muscles enjoy a steady stream of energy instead of one gigantic sugar rush and a corresponding crash.

Is GU safe for children?

Yes, if they’re playing sports, on a hike or just being active, GU will help kids just as much as it helps you. You’d probably want to keep them away from the flavors that contain caffeine; no need to make them more hyperactive.

Can my dog eat GU?

We don’t recommend it. Maltodextrin is corn-based and corn is not recommended for dogs—many are actually allergic to corn.

Is GU Energy Gel Kosher?

GU Energy Gel, Roctane, GU Electrolyte Brew, and GU Recovery Brew are all certified Kosher. Chomps are not.

    I don't go anywhere without my GU. These have kept me going through multiple ironmans, marathons, mountain summits, skiing days, etc. Haven't had a bad flavor yet, but the Jet Blackberry rocks... especially on pancakes!

    Posted by Taylor on 12/16/2013
    I alternated between these and Gu Roctanes during my ironman training process. These were great for shorter workouts where I wanted to really enjoy my energy gel, whereas the Gu Roctanes were better for 5-8 hour rides

    Overview
    Posted by anthony on 12/6/2013
    I had never used GU before receiving it at a refreshment/water station during a distance race at mile 10. Within a quarter of a mile I could literally feel my energy pick up. The taste was good but it was a little thick (though that was not a problem because I had it with water). Can't wait to receive my first shipment to help me on my training days.
  • The best gel out there!

    Posted by Jay on 12/6/2013
    I have been competing in triathlon about three years now. I tried Gu first, and it's still my favorite. I live the Espresso Love early, then I switch to PeanutButted with the Vanilla in there once in a while. Other brands tend to upset my stomach. Gu never does. Great product!

    Posted by Geo on 12/5/2013
    I do all different distance races and I don't rely on anything else but Gu gel products. They get me moving, keep me going, and help me finish strong. Can't go wrong with any of the flavors!
