Product Description

DL-Carnitine Synonyms: 3-Hydroxy-4-(trimethylammonio)butanoate Molecular Structure: Molecular Formula: C7H15NO3 Molecular Weight: 161.20 CAS Registry Number: 406-76-8 EINECS: 206-976-6 Carnitine comes in the two stereo-isomer forms, L-carnitine and D-carnitine. It is only the L form which is biologically active. Some health food versions of carnitine are L-carnitine, and some are a mixture of the L- and the D- forms (DL-carnitine). Because it is much easier to make, DL-carnitine is often much cheaper. There is some evidence to suggest that D-carnitine may be harmful; there may also be some safety issues with the quality of some health food carnitine relating to the imported sources of the bulk chemical. The FDA has issued an Import Alert warning about DL-carnitine. "
