Patient Education

Betaine


Betaine is used to treat homocystinuria (an inherited condition in which the body cannot break down a certain protein, causing build-up of homocysteine in the blood). Increased amounts of homocysteine in the body can cause symptoms such as extreme tiredness, seizures, dislocation of the lens of the eye, abnormal bone structure, osteoporosis (weak bones), blood clots, or decreased weight or rate of weight gain and slowed development in children. Betaine is in a class of medications called nutrients. It works by decreasing the amount of homocysteine in the blood.
