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

effective method to keep athletes fueled during exercise and speed their recovery from exertion. Today thousands of elite
athletes and millions of endurance enthusiasts around the world agree: GU works.
Energize:
A shot of fast-acting natural fructose (fruit sugar) goes straight to work building your energy levels back up while the
maltodextrin is quickly absorbed and sent to your muscles. Vital electrolytes keep your blood chemistry in line and
hydration levels stable. Calcium keeps your muscles humming and caffeine adds an extra kick to your power.
Sustain:
Complex carbs in the form of maltodextrin (70-80% of the complex/simple carbohydrates blend) help you maintain
glucose levels over time. Citrates (potassium citrate, sodium citrate and citric acid) help speed the conversion of
these carbs into energy molecules and mitigate performance-sapping acid build-up in muscles. Branched chain amino
acids (BCAAs) leucine, valine and isoleucine, serve as another fuel source, aid in recovery and can improve mental
performance and reduce fatigue by limiting the central nervous system’s production of serotonin. Histidine, an essential
amino acid, acts alongside the citrates as a buffer that helps neutralize lactic acid build-up in muscles.
Recover:
Antioxidant vitamins C & E defend muscles from assault by free radicals. Chamomile works as an anti-inflammatory
during and after exercise. Ginger soothes the stomach. Sea salt supplies a host of minerals.
