Betaine, or TMG, is also involved in the manufacture of carnitine, and helps protect the kidneys from damage. Betaine HCl, or betaine hydrochloride, is an supplemental, chloride-salt form of betaine that is useful as a digestive aid.
Betaine is a derivative of the nutrient choline; in other words, choline is a âprecursorâ to betaine and must be present for betaine to be synthesized in the body. Betaine is created by choline in combination with the amino acid glycine.. Betaine is used to treat alcoholic liver damage that results in the accumulation of fat in the liver. Betaine has lipotropic (fat-reducing) effects, so it has been shown to produce significant improvements in healing fatty liver disease by helping the liver to process and remove fats.
