L-Carnitine is important for providing energy to muscles, and has been described as a "conditionally essential" nutrient for humans. 95% of all carnitine stored in the body are found in muscle tissue. It carries fatty acids into the mitochondria of each cell, where they are oxidized and stored as ATP, a prime energy fuel.
