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.
- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
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.
This supplement has been used in connection with the following health conditions:
Hepatitis and Nonalcoholic Steatohepatitis
|20 grams daily||[2 stars] |
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.
|1.5 to 6 grams daily||[2 stars] |
Betaine (trimethylglycine) has been shown to lower homocysteine levels.
|Refer to label instructions||[1 star] |
For the few cases in which vitamin B6, vitamin B12, and folic acid fail to normalize homocysteine, adding betaine (trimethylglycine) may be effective.
