Betaine anhydrous is a chemical that occurs naturally in the body, and can also be found in foods such as beets, spinach, cereals, seafood, and wine.
Betaine anhydrous is approved by the U.S. Food and Drug Administration (FDA) for treatment of high urine levels of a chemical called homocysteine (homocystinuria) in people with certain inherited disorders. High homocysteine levels are associated with heart disease, weak bones (osteoporosis), skeletal problems, and eye lens problems.
Betaine anhydrous is also used for treating high blood homocysteine levels, liver disease, depression, osteoarthritis, congestive heart failure (CHF), and obesity; for boosting the immune system; and for improving athletic performance. It is also used for preventing noncancerous tumors in the colon (colorectal adenomas).
Topically, betaine anhydrous is used as an ingredient in toothpastes to reduce the symptoms of dry mouth.
