GU Energy | The Science Behind The Worlds Best Energy Gel since 1991

Through constant scientific development of GU Energy Gels since their launch in America in 1991, GU Energy Gels are the most efficient source of premium fuel available on the market for athletes worldwide. If you have tried other gels, you will appreciate that GU Energy Gels have been developed to deliver high-quality energy and electrolytes without upsetting your stomach whilst you exercise. GU Gels feed in energy to replenish your muscles glycogen stores and mitigate the effects that lactic acid build up has on your energy levels. There’s a lot going on in every packet of GU and it’s all designed to help you hit your personal best in whatever sport you are pushing yourself in.

Maltodextrin & Fructose – A Blend for success

Depending on which flavour you choose, GU Gels consist of 70-80% Maltodextrin and 20-30% Fructose. As a complex carbohydrate, Maltodextrin is digested quickly and easily by the body which means your body doesn’t have to divert too much blood to your stomach to digest the GU and your muscles are not deprived of oxygenating blood when they most need it. In this way, Maltodextrin is far better than sugar or honey for example which are less easily digested and produce a sugar “high” which you need to avoid whilst exercising. After your exercise, eating a GU will help replenish your muscles glycogen stores. The Fructose is present in GU Gels because it is digested even quicker than Maltodextrin and provides fast energy to your body without creating a sugar “spike”, it also sweetens the GU Gels but not so much that they taste sickly like some other gels on the market.

GU Gels Amino Acid Blend

Over the last 20 years, the scientists at GU have developed, tweaked and perfected a secret and unique blend of amino acids which help to combat muscle fatigue and make sure the carbohydrates in each gel packet are converted into energy and keep you focused on achieving the best times you can.

Histidine

An integral part of GU Energy Gels amino acid blend, Histidine helps reduce “the burn” you feel when you stress your muscles during intense exercise. In a nutshell, it helps to keep your muscles pushing hard for longer and improves the muscles recovery rate because less burn means less damage.

Citrates (Potassium Citrate, Sodium Citrate and Citric Acid)

GU Gel’s formula includes citrates to help your body create energy molecules which are used by the muscles to power you on your way to your personal best. The easier GU Gels makes it to produce these molecules, the faster you can go!

Branched Chain Amino Acids (Leucine, Valine and Isoleucine)

BCAAs are a pretty important ingredient in every GU Energy Gel. They are used as fuel by your body when you’re exercising hard, they help in the conversion of protein to fuel and they also slow down your body breaking down its own muscle to use as fuel. There is also research which shows that BCAAs help you stay more alert and focused by suppressing feeling of fatigue and sleepiness.

Calcium and Caffeine to improve your performance

The Calcium added to each GU Gel packet replaces Calcium lost during exercise and there is some research linking muscle fatigue with calcium loss; GU Gels keep you topped up. The Caffeine in GU Energy Gels acts as a stimulant for exercise and helps your body burn fat to provide fuel as you go. The only non-caffeinated GU Gels are Lemon Sublime and Strawberry Banana, apart from those, the other GU Gels have 20mg of Caffeine in them or, in the case of Espresso Love and Jet Blackberry, 40mg of Caffeine which gives you that extra kick just when you need it.

GU Antioxidant Blend – Muscle Protection

As you work out hard your muscles are under stress and the tissue can get damaged. GU Gels Antioxidant Blend of Vitamin C and Vitamin E help to provide a defence system against free radical damage to the tissue caused when there is an increase of oxygen to the muscles as you work out.

GU Herbal Blend – Naturally Soothing

Last but by no means least, the blend of chamomile and ginger in each GU Gels packet soothe your stomach whilst it digests the GU. For some people, the secret GU Herbal Blend is the reason they can only eat GU on the run – nothing else digests as easily!

Every ingredient in every GU Gel packet is there for a reason – to help you achieve your performance goals faster and with minimal stress on your body – it is as simple as that.
