Background

Betaine is found in most microbes, plants, and marine animals. Its main functions are to protect cells under stress and support important body functions and processes. Betaine is also found naturally in many foods and is highly present in beets, spinach, grain, and shellfish.
Betaine has been used to treat homocystinuria, a genetic disorder in which the body cannot properly break down certain amino acids. Betaine may reduce levels of homocysteine in the bloodstream, a potential risk factor for heart disease, stroke, cancer, and Alzheimer's disease. The effects of betaine may be stronger in people who are not taking B vitamin supplements.
Betaine is thought to benefit both alcoholic and non-alcoholic fatty liver disease. However, further research is needed in this area.
Betaine alone or with other treatments has been studied for bad breath, dry mouth, exercise performance, birth control, acid reflux, liver inflammation, brain development disorders, skin damage from the sun, weight loss, and wound care. Further studies are needed before these uses can be supported. Early research suggests that betaine may lack effect on heart disease or high cholesterol in people without high levels of homocysteine.
A form of betaine called cocamidopropyl, which is found in some skin care products, may cause allergic skin reactions. This form of betaine has been studied for use in toothpastes for dry mouth, ulcers, and other irritations.

A


Homocystinuria is a severe form of a genetic disorder in which there is a very high level of homocysteine in the bloodstream, a risk factor for heart disease. Betaine may benefit people who have severely high homocysteine levels due to genetics, in combination with other vitamins and diet changes. Further studies are needed to determine whether betaine may lower heart disease risk in the general population.

Further studies are needed to determine whether betaine may lower heart disease risk in the general population.

Overall, betaine has been shown to significantly reduce homocysteine levels by as much as 20 percent. Lower homocysteine levels have been associated with a 20-30 percent reduction in heart disease risk in some people. Further research is needed to determine the effects of betaine in people with nutrient deficiency and its possible effectiveness for lowering the risk of some chronic diseases, such as stroke or cancer.

A mouthwash containing betaine, xylitol, and sodium fluoride has been found to help improve saliva flow. However, a night guard was found to be more effective at improving dry mouth symptoms, such as difficulty swallowing. In other research, dry mouth products containing olive oil, betaine, and xylitol reduced dry mouth symptoms and improved quality of life. The effects of betaine alone are unclear from these studies. Further research is needed before conclusions may be made.

Treatment with betaine may improve body composition, arm size, work capacity for bench press, power, fatigue, and protein synthesis after exercise. However, it was found to lack a significant effect on strength. Evidence is mixed. Further studies are needed before conclusions may be made.

Hyperhomocysteinemia is a complication found in 80 percent of cases of late-stage, severe kidney failure, and may increase the risk of clogged arteries in these people. Betaine has been studied in combination with folic acid in this population. A lack of further benefit of betaine has been found among people who take folic acid and vitamin B6 in much greater amounts than the daily recommended intake. More research is needed.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (18 years and older)
General: Currently, there is no recommended daily allowance (RDA) set by the United States Food and Nutrition Board for betaine. Manufacturers recommend that betaine powder be dissolved in water, juice, milk, or formula prior to administration and be administered in two doses of 3 grams each.
For heart disease in people with homocystinuria, 2-15 grams of betaine have been taken by mouth daily for up to 17 years.
For high cholesterol levels, 1.5-6 grams of betaine has been taken by mouth daily for six weeks to six months, with a lack of benefit.
For heart disease in people without high homocysteine levels, 3 grams of betaine has been taken by mouth twice daily for six weeks, with a lack of benefit.
For exercise performance, 2-5 grams of betaine has been taken by mouth (as capsules or mixed with juice) daily for up to six weeks.
For high homocysteine levels, 0.5-6 grams of betaine (often mixed with orange juice) has been taken by mouth daily for up to six months.
For high homocysteine levels in people with severe kidney failure, 4-6 grams of betaine has been taken by mouth in two divided doses daily for up to three months.
For non-alcoholic fatty liver disease, Cystadane? has been taken by mouth in doses of up to 20 grams daily for up to one year.
For weight loss, 3 grams of betaine mixed with orange juice has been taken by mouth twice daily for 12 weeks, with lack of benefit.
