Additional Information

L-Carnitine acts as a carrier of fatty acid molecules into the mitochondria of heart and skeletal muscle, where fatty acids can be utilized by the tissue cells as a source of energy. L-Carnitine is a naturally-occurring compound, with highest concentrations found in heart and skeletal muscle and dairy products.
