Product Description

GU is simple. Simple is fast. 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.

Created for daily training and competition, GU Energy Gel packs energy-dense calories in a portable packet to help sustain energy demands of any duration or activity. The 100-calorie packet contains carbohydrates (maltodextrin and fructose) that use non-competing pathways to help maximize carbohydrate absorption and utilization while diminishing stomach distress. Sodium, the primary electrolyte lost in sweat, aids in hydration by maintaining water balance. The branched-chain amino acids (leucine, valine, isoleucine) may reduce mental fatigue and decrease muscle damage.

When you’re working out, you need easy-to-digest calories from carbohydrates that deliver immediate and sustained energy while reducing risk of stomach distress.

The precise blend of complex and simple carbohydrates will fuel you up, so you feel good, longer. Our huge variety of delicious flavours will save you from flavour fatigue, so you can stick to your nutrition plan and keep going.

How does it work?

GU Original Energy Gel works by providing a concentrated source of carbohydrates, electrolytes, and BCAAs to fuel and support athletic performance. The gel is designed to be quickly and easily consumed during physical activities, delivering a burst of energy to meet the demands of the body.

When consumed, the carbohydrates in the gel, derived from maltodextrin and fructose, are rapidly broken down and converted into glucose. This glucose serves as the primary source of fuel for the muscles, providing immediate energy to sustain performance. The combination of fast-acting and long-lasting carbohydrates ensures a steady release of energy, preventing sudden spikes and crashes.

In addition to carbohydrates, the gel contains electrolytes, including sodium, which play a crucial role in maintaining hydration and optimizing muscle function. These electrolytes help replace the sodium lost through sweating, ensuring proper fluid balance and preventing dehydration. By taking the gel with a few sips of water, the body efficiently absorbs the fuel and electrolytes, maximizing their effectiveness.

GU Original Energy Gel includes BCAAs (Branched-Chain Amino Acids), which are essential for muscle health and performance. BCAAs help protect muscles from breakdown during intense exercise, contribute to energy production, and aid in reducing mental fatigue. By providing this essential amino acid blend, the gel supports muscle integrity, endurance, and recovery.

How do you use GU Original Energy Gel?

GU pack 100 calories into our Energy Gels because, in general, the body can digest roughly 120-240 calories per hour during exercise. If you tried to eat more, the body would divert blood from your muscles back to the gut to handle the excess food/calories. If your metabolism is slower, then one Energy Gel every 45 minutes works just fine. If you have a faster metabolism, try ingesting one Energy Gel every 30 minutes and see if it agrees with your digestion system. We always recommend practicing your nutrition plan to determine what works best for you.
