L-Carnitine Carnitine promotes the use of fat by the body. Carnitine supplementation can improve the utilization of fat as an energy source by transporting long-chain fatty acids into the energy-producing units (mitochondria) of the cells. Carnitine supplementation supports healthy cardiovascular function during exercise as shown in several double-blind studies in both athletes and normal subjects. Carnitine supports peripheral vascular function as well as nerve function.
