- Betaine is found in most microorganisms, plants, and marine animals. Its main physiologic functions are to protect cells under stress and as a source of methyl groups needed for many biochemical pathways. Betaine is also found naturally in many foods and is most highly concentrated in beets, spinach, grain, and shellfish.
- Betaine supplementation has historically been used in the treatment of homocysteinuria due to genetic deficiencies in the cystathione beta synthase and methylenetetrahydrofolate reductase genes.
- Betaine supplementation may reduce circulating levels of homocysteine, a potential risk factor for heart disease, stroke, cancer, and Alzheimer's disease.
- Betaine supplementation has been thought to improve hepatic steatosis, from both alcoholic and nonalcoholic etiologies. While many animal studies have provided plausible mechanisms, data from human studies are limited.
- Betaine in the form of cocamidopropylbetaine has been identified as a cause of contact allergy in some skin care products. In this same form, betaine has been studied as a potential replacement for sodium lauryl sulfate in toothpastes to reduce dry mouth, ulcers, and other mucosal irritations.
- Since the 1980s, betaine has been used as a treatment option for subjects who have homocystenuria, due to a genetic defect in the cystathione beta-synthase (CBS) gene. Pyridoxine (vitamin B6) was beneficial in only 50% of CBS patients, and betaine was a therapeutic option for homocysteine reduction in these unresponsive patients. Benefit was also seen among pyridoxine-responsive patients.
- Early anecdotal reports showed that among CBS variants, treatment with betaine, in addition to B6 and methionine restriction, prevented or delayed clinical complications of the disease, including cardiovascular disease before age 30.
