- DrugBank Accession Number
- DB06756
- Background
Betaine is a methyl group donor that functions in the normal metabolic cycle of methionine. It is a naturally occurring choline derivative commonly ingested through diet, with a role in regulating cellular hydration and maintaining cell function.3,4 Homocystinuria is an inherited disorder that leads to the accumulation of homocysteine in plasma and urine. Currently, no treatments are available to correct the genetic causes of homocystinuria. However, in order to normalize homocysteine levels, patients can be treated with vitamin B6 (pyridoxine), vitamin B12 (cobalamin), folate and specific diets.7 Betaine reduces plasma homocysteine levels in patients with homocystinuria.5 Although it is present in many food products, the levels found there are insufficient to treat this condition. The FDA and EMA have approved the product Cystadane (betaine anhydrous, oral solution) for the treatment of homocystinuria,5,7 and the EMA has approved the use of Amversio (betaine anhydrous, oral powder).6

Pharmacology
- Indication
Betaine is indicated for the treatment of homocystinuria in pediatric and adult patients to decrease elevated homocysteine blood levels.5 Included within the category of homocystinuria are deficiencies or defects in cystathionine beta-synthase (CBS), 5,10-methylenetetrahydrofolate reductase (MTHFR), and cobalamin cofactor metabolism (cbl).5

Betaine decreases plasma homocysteine concentrations in homocystinuria cases caused by deficiencies or defects in cystathionine beta-synthase (CBS), 5,10-methylenetetrahydrofolate reductase (MTHFR), and cobalamin cofactor metabolism (cbl).5 The decrease of homocysteine is estimated to be 20-30% of pre-treatment levels. Betaine supplementation in patients with homocystinuria also improves metabolic abnormalities in cerebrospinal fluid.6 Reports have shown that depending on the type of homocystinuria, the therapeutic effectiveness of betaine alone may be limited, insufficient to decrease total homocysteine levels and prevent clinical symptoms. In patients with homocystinuria due to cystathionine beta-synthase (CBS) deficiency, betaine should be used when serum total homocysteine levels remain high despite dietary therapy.1
Patients taking betaine for several years do not show evidence of tolerance. Also, betaine concentrations are not correlated with homocysteine concentrations.5 In patients with MTHFR deficiency and cbl defects, betaine may increase methionine and S-adenosyl methionine (SAM) plasma levels. Patients with CBS deficiency without a dietary restriction of methionine may accumulate excessive amounts of methionine. Clinical data shows that in patients with CBS deficiency, increased plasma methionine levels were associated with cerebral edema.5,6
- Mechanism of action
Homocystinuria is a hereditary disorder characterized by high levels of the amino acid homocysteine. This condition can be caused by deficiencies or defects in cystathionine beta-synthase (CBS), 5,10-methylenetetrahydrofolate reductase (MTHFR), and cobalamin cofactor metabolism (cbl).5 CBS converts homocysteine to cystathionine, and a deficiency in this enzyme can lead to an accumulation of homocysteine. MTHFR is responsible for producing 5-methyltetrahydrofolate, a methyl donor that participates in the conversion of homocysteine back to methionine; therefore, an MTHFR deficiency can also lead to homocystinuria.4 Additionally, a defect in cobalamin (vitamin B12) cofactor metabolism can lead to homocystinuria, since a metabolite of cobalamin (methylcobalamin) promotes the conversion of homocysteine to methionine.3
Betaine transfers a methyl group via the enzyme betaine homocysteine methyl transferase (BHMT), converting homocysteine back into methionine and dimethylglycine (DMG).4,6 In patients with homocystinuria, betaine reduces homocysteine levels and improves health outcomes.3
Target Actions Organism ABetaine--homocysteine S-methyltransferase 1 substrateHumans - Absorption
Betaine is rapidly absorbed and distributed. In healthy volunteers (n=12) given 50 mg/kg of betaine, the Cmax, tmax and AUC0,∞ were 0.939 mmol/L, 0.90 h and 5.52 mmol⋅h/L, respectively.2 No significant changes in absorption kinetics were observed after repeated betaine administration (100 mg/kg/day for 5 days). The absolute bioavailability of betaine anhydrous has not been determined.6
- Volume of distribution
Based on a study done on healthy volunteers (n=12) given 50 mg/kg of betaine, the volume of distribution was 1.3 L/kg.2
- Protein binding
Not Available
- Metabolism
Betaine is catabolized mainly in the mitochondria of liver and kidney cells. The transmethylation of betaine via betaine homocysteine methyl transferase (BHMT) leads to the formation of dimethylglycine.3

- Route of elimination
Betaine is mainly eliminated by metabolism.2 With a slow elimination rate and assuming 100% bioavailability, the renal clearance of betaine is negligible (5% of total body clearance).6
- Half-life
In healthy volunteers (n=12) given 50 mg/kg of betaine, the elimination half-life was 14.38 h.2 In volunteers given 100 mg/kg/day of betaine for 5 days, the distribution half-life was significantly longer, suggesting that the transport and redistribution processes of betaine were saturated.6
- Clearance
Based on a study done on healthy volunteers (n=12) given 50 mg/kg of betaine, total oral plasma drug clearance was 0.084 L/h⋅kg.2

Toxicity information regarding betaine is not readily available. Patients experiencing an overdose are at an increased risk of severe adverse effects such as cerebral edema in patients with cystathionine beta-synthase (CBS) deficiency.5 Symptomatic and supportive measures are recommended. In an acute toxicology study in rats, death frequently occurred at doses equal to or greater than 10,000 mg/kg.5 The effects of betaine on long-term carcinogenicity and fertility have not been evaluated. The following tests have not shown evidence of betaine genotoxicity: metaphase analysis of human lymphocytes, bacterial reverse mutation assay, and mouse micronucleus test.5
