    Product Description

    L-Carnitine is a conditionally essential nutrient.1 It is obtained from dietary sources or through the metabolism of lysine and methionine.2,3 L-Carnitine facilitates the transport of long-chain fatty acids into the mitochondrial matrix for β-oxidation, has other diverse roles on metabolism, and is involved in the maintenance of coenzyme A (CoA; Item No. 16147) stores. Plasma and/or tissue levels of L-carnitine are decreased in primary L-carnitine deficiency, a disorder characterized by impaired fatty acid oxidation, with symptoms varying depending on whether it is systemic or muscle-specific.1 Serum and tissue levels of L-carnitine are also reduced in secondary L-carnitine deficiencies caused by a variety of hereditary defects or acquired disorders.

    WARNING This product is not for human or veterinary use.
