Hi-Octane is a processed fat supplement consisting of highly available fatty acids which are rapidly absorbed and converted to energy in working muscles. The energy available from fats 2.3 times greater than that from equivalent glycogen sources. By consuming fats as an energy source, the canine athlete is able to conserve glycogen for the severe exertion of sprinting in the later stages of a race, hence improving endurance, and delaying the onset of muscle fatigue and cramping.
