Tasty, Portable Energy for Athletes

GU Original Energy Gels pack quick, effective, and sustained energy to meet the demands of all types of activity, in a convenient packet small enough to fit in your pocket.

Roctane takes athletes' top choice for an energy gel, GU, amplifies the original recipe and then adds new ingredients to boost performance in sustained, high-intensity efforts.
Uses original GU's superior mix of complex and simple carbohydrates that provide quick and sustained energy, electrolytes for replenishment and caffeine to tap more power and diminish pain.
Increased amount of histidine, an essential amino acid, to act as a buffer and slow the energy-sapping lactic acid build-up in muscles.
Higher levels of citrates (potassium citrate, sodium citrate, and citric acid) to help speed the conversion of carbohydrates into energy molecules and, like histidine, help mitigate acid build-up.
More branched chain amino acids (BCAAs) leucine, valine and isoleucine to serve as another fuel source, aid in recovery and help maintain mental focus and reduce fatigue by limiting the central nervous system's production of serotonin.
Addition of a new ingredient, the amino acid complex Ornithine Alpha-Ketoglutarate (OKG) which limits the body's tendency to break down muscle protein tissue during extremely hard training and racing days. OKG keeps you going longer and promotes a speedier recovery.
