What is DL-Carnitine?
The Uses of DL-Carnitine
DL-Carnitine is a Chloride salt free form of D,L-Carnitine Chloride (C184100). Carnitine is a vitamin, essential cofactor of fatty acid metabolism. It is required for the transport of fatty acids through the inner mitochondrial membrane. Synthesized primarily in the liver and kidney; highest concentrations found in heart and skeletal muscle. Dietary sources include red meat, dairy products, beans, avocado.
