Biochem/physiol Actions

Carnitine is a quaternary amine that occurs naturally in most mammalian tissue. It is present in relatively high concentrations in skeletal muscle and heart where it is involved in regulating energy metabolism. It shifts glucose metabolism from glycolysis to glycogen storage and enhances the transport of long chain fatty acids into the mitochondria where they are oxidized for energy production.


Unit quantity: 15 mg. Subject to change. The product is delivered as supplied by the issuing Pharmacopoeia. For the current unit quantity, please visit the EDQM reference substance catalogue.
