Betaine
Betaine is a nutrient that plays an important role in the health of the cardiovascular system. Studies have suggested that betaine, along with other nutrients, helps to reduce potentially toxic levels of homocysteine (Hcy), a naturally occurring amino acid that can be harmful to blood vessels thereby contributing to the development of heart disease, stroke, and peripheral vascular disease (reduced blood flow to the legs and feet).
Betaine functions closely with other nutrients -- namely, S-adenosylmethionine (SAMe), folic acid, and vitamins B6 and B12 -- to break down Hcy and reduce toxic levels of this substance in the bloodstream. When betaine, or any of these related nutrients, becomes low in the body, Hcy levels may rise. Some people have a genetic condition called "homocystinuria," in which Hcy levels accumulate in the body. Betaine supplements are used to lower levels of Hcy in people with this inherited health condition.
