Trimethylglycine : Uses, Side Effects, Interactions & More
Trimethylglycine (TMG) is an amino acid derivative that occurs in plants.

Since then, many other betaines have been discovered, and the more specific name glycine betaine distinguishes this one.
Why is this medication prescribed?
Trimethylglycine (Betaine) is used to treat homocystinuria (an inherited condition in which the body cannot break down a certain protein, causing homocysteine to build up in the blood). Increasing the amount 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 the rate of weight gain. and slow development in children.
