Simple to take, simple to digest, GU Energy Gel provides just what you need for premium exercise fuel and none of the extras that slow you down. GU takes you where you want to go, fast.

Launched in 1991, the world’s first energy gel is still the most efficient sports fuel available today. GU’s carbohydrate blend delivers high-quality, easily-digested and long-lasting energy for athletes in every sport and at all levels.

GU Energy Gel is a convenient, great tasting carbohydrate gel formulated to energize before, sustain during, and aid in recovery after your training and competitions. Made with a unique blend of ingredients, GU provides: complex carbohydrates for sustained energy, amino acids to maintain muscle protein, antioxidants and muscle buffers to aid with recovery and GU``s herbal blend for enhanced energy production. GU helps you feel and perform your best.

GU Energy Gel is specifically formulated to energize your body during exercise. Using GU during your regular workouts will keep your mind alert and active, and your muscles going strong. GU gives the most concentrated form of immediate energy with no stomach bulk or distress, is quickly and efficiently absorbed, and will maintain your blood sugar at the optimal level for a great workout start to finish.

During a workout or race, no matter what type, you need to quickly absorb carbohydrate-based calories to replace the glucose you are burning at 400 - 600 per hour or you will begin to lose concentration and energy. The fat, fiber and protein found in bars are very slow to absorb and create unwanted bulk in the stomach. GU is created for the body during exercise, and because of its form and ingredients is absorbed much faster than a bar so you will feel the energy almost immediately.

GU Energy Gel contains maltodextrin, the best complex carbohydrate for delivering energy to working muscles. GU also contains the optimal balance of carbohydrates for the body during exercise: 80% complex/20% simple. It is this balance of maltodextrin and fructose in GU that delivers a quick rise in blood sugar and maintains that glucose level for up to 45 minutes during exercise.

By simply adding GU to your normal workout routine - one packet 15 minutes before starting then one packet every 45 minutes or so - you will feel strong and energized, be able to maintain your effort throughout the workout, feel better when you finish, and recover quickly for your next workout. If you want to have a good workout you have to supply your body with the right fuel - GU Energy Gel.


How to Use GU

Follow these three simple steps to maximize your athletic performance:

1. Top off your energy stores by taking one packet of GU 15 minutes before exercise, preferably on an empty stomach for fastest absorption.

2. For sustained energy consume one packet of GU every 35-45 minutes during exercise, washing it down with a few mouthfuls of water or GU2O hydration drink to speed absorption.

3. Speed recovery and reduce post-exercise fatigue by eating one packet of GU within 30 minutes of finishing your workout. This takes advantage of the post-exercise time window when your body replenishes lost glycogen most efficiently.

Who should use GU?
GU is for anyone who is active, whether that person exercises moderately for a healthier lifestyle or training for an endurance event. Athletes of all types and abilities train, race, and benefit from using GU Energy Gel.

Why is GU different from other gels?
Gel ingredients may look similar when comparing the labels, but GU has more performance ingredients than any other gel. GU contains up to 500% more essential amino acids, antioxidants, herbs, and muscle buffers than its competitors.

Production quality:
GU is mixed and packaged at our headquarters in Berkeley, CA. We do everything ourselves so we can guarantee the quality of the product you use. All of our competitors contract out to third parties to produce and package their gels.

Flavor
If it doesn``t taste good, why eat it? We only use gourmet natural vanilla, real Belgian chocolate, and the finest natural fruit flavorings available. GU tastes as good as it performs.

Why eat GU instead of food or an energy bar?
GU delivers quick sustained energy without the fat, fiber and protein that energy bars contain. When you exercise, the blood supply usually used to digest solid food is utilized to cool your body temperature and feed your muscles oxygen and glucose. This dramatically slows down the digestion process, so the bulky fiber and hard to digest fats and proteins interfere with absorption and may cause stomach distress and bloating. GU does not contain those ingredients - just the ones you need to keep going and improve your performance.

Should I take water with GU?
Yes. GU is formulated to work best when followed by a few mouthfuls of water or GU2O immediately after consumption. The fluid speeds up absorption.

Does GU contain caffeine?
Yes. All flavors, except Banana Blitz, contain 20mg of caffeine (about 1/5 cup of coffee) from cola nut extract. The level of caffeine in GU is not enough to give a "caffeine rush," but is added to help you utilize body fat as an additional fuel source during activity.

Can I take GU on an empty stomach?
Yes. GU is most effective when eaten on an empty stomach. The rate of absorption is maximized when the stomach is empty.

GU Ingredients

Carbohydrates: Carbohydrates provide the quick, sustained energy source in GU. 85% are complex carbohydrates from maltodextrin and 15% are simple carbohydrates from fructose.

Amino Acids: Leucine and Valine are two vital amino acids in GU that help maintain muscle protein and aid with recovery.

Antioxidants: Vitamins C and E are important antioxidants in GU. They help protect against tissue damage from free radicals, which are produced by the muscle``s burning of oxygen. GU contains 100% RDI of vitamins C & E in each packet to protect your tissues, help reduce soreness and aid with recovery.

Muscle Buffers: Histidine, another amino acid in GU, buffers against lactic acid buildup in your muscles. This helps alleviate muscle fatigue while exercising and soreness during recovery. GU is the only gel that contains histidine.

Herbal Blend: GU``s unique herbal blend combines the perfect fusion of herbs for energy-enhancement (cola-nut), anti-inflammatory (chamomile), and stomach buffering (ginger).

Caffeine: Espresso Love contains an added jolt of 40 mg of caffeine, while Strawberry Banana and Lemon Sublime have none at all. All other flavors contain 20mg (equivalent to 1/5 cup of coffee) per serving from cola-nut. The caffeine level in GU is not enough to give a "caffeine rush," but is added to help you utilize body fat as an additional fuel source during activity.

What is the best time to use GU? Eat one packet about 15 minutes before your workout, when your stomach is empty if possible. Then take a packet every 35 - 45 minutes during activity followed by a few mouthfuls of water or GU2O hydration drink to sustain your energy. Finally, we recommend taking one packet within 30 minutes of finishing your workout to aid in recovery and increase the glycogen stores in your muscles.
