L-Carnitine is primarily involved with transporting long-chain fatty acids from the cell cytosol into the mitochondria. Since long chain fatty acids are oxidized (burned) in the mitochondria, L- Carnitine facilitates production of energy from fat. Oxidation (combining with oxygen) of the BCAAs is facilitated by L- Carnitine, providing a link between protein catabolism and cellular energy. Skeletal muscle contains 90% of total body carnitine in humans. L-Carnitine's Function during Aerobic Exercise: ´¢ Helps Increase Fat Metabolism ´¢ Increases Endurance ´¢ Improves Definition ´¢ Increases Utilization of Fatty Acids as Energy ´¢ Decreases Lactate Build Up ´¢ May Help in the Reduction of Ketones in the Blood. (important for diabetics)
