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.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
| Used for | Why |

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. |
How It Works
How to Use It
For people with alcohol-induced fatty liver, the recommended amount for betaine citrate or betaine aspartate supplementation is 1,000 to 2,000 mg three times daily. Lower amounts are often used as nutritional support for general liver health, although use of betaine in this manner has not undergone clinical research.
Where to Find It
Dietary sources of betaine include fish, beets, and legumes. Betaine is most widely available as betaine hydrochloride (betaine-HCl), but that form is used primarily as a source of hydrochloric acid for people with hypochlorhydria (low stomach acid). The forms used specifically to provide betaine are betaine citrate and betaine aspartate. These forms have also been used to improve liver function.
Possible Deficiencies
Betaine is not an essential nutrient, and thus no deficiency state exists.
