Betaine (Trimethylglycine)

Uses

Betaine (trimethylglycine) functions very closely with choline,folic acid, vitamin B12, and a form of the amino acid methionine known as S-adenosylmethionine (SAMe).1, 2 All of these compounds function as “methyl donors.” They carry and donate methyl molecules to facilitate necessary chemical processes. The donation of methyl groups by betaine is very important to proper liver function, cellular replication, and detoxification reactions. Betaine also plays a role in the manufacture of carnitine and serves to protect the kidneys from damage.3 Betaine is closely related to choline. The difference is that choline (tetramethylglycine) has four methyl groups attached to it. When choline donates one of these groups to another molecule, it becomes betaine (trimethylglycine). If betaine donates one of its methyl groups, then it becomes dimethylglycine.

What Are Star Ratings?

This supplement has been used in connection with the following health conditions:

Used forWhy
2 Stars
Hepatitis and Nonalcoholic Steatohepatitis
20 grams daily
Supplementing with zinc (in the form of a zinc complex of L-carnosine) enhanced the response to interferon therapy in patients with chronic hepatitis C in a preliminary trial.

In a preliminary trial, supplementation with (20 grams per day) for 12 months improved signs of liver inflammation in seven patients with nonalcoholic steatohepatitis, a type of liver inflammation. No significant side effects were seen.

2 Stars
High Homocysteine
1.5 to 6 grams daily
Betaine (trimethylglycine) has been shown to lower homocysteine levels.

(6 grams per day) and choline (2 grams per day) have each been shown to lower homocysteine levels. Choline in the amount of 2.6 grams per day (provided as 34 grams per day of soy lecithin) has also been shown to lower homocysteine levels in a double-blind trial. More recently, 1.5 grams of betaine per day, an amount similar to that in a typical diet, also has been found to lower homocysteine levels. Doctors usually consider supplementation with these nutrients only when supplementation with folic acid, vitamin B6, and vitamin B12 do not reduce homocysteine levels sufficiently. The results of this study, however, point to the potential benefit of increasing one’s intake of foods rich in betaine (such as whole wheat, spinach, beets, and other plant foods).

1 Star
Atherosclerosis
Refer to label instructions
For the few cases in which vitamin B6, vitamin B12, and folic acid fail to normalize homocysteine, adding betaine (trimethylglycine) may be effective. Regular (anhydrous) betaine is preferable to betaine hydrochloride for most people (check with a doctor).

Blood levels of an amino acid called homocysteine have been linked to atherosclerosis and heart disease in most research, though uncertainty remains about whether elevated homocysteine actually causes heart disease. Although some reports have found associations between homocysteine levels and dietary factors, such as coffee and protein intakes, evidence linking specific foods to homocysteine remains preliminary. Higher blood levels of vitamin B6, vitamin B12, and folic acid are associated with low levels of homocysteine and supplementing with these vitamins lowers homocysteine levels.

For the few cases in which vitamin B6, vitamin B12, and folic acid fail to normalize homocysteine, adding 6 grams per day of may be effective. Of these four supplements, folic acid appears to be the most important. Attempts to lower homocysteine by simply changing the diet rather than by using vitamin supplements have not been successful.
