OriginSynthesized from naturally occurring amino acids or derived from sugar beet molasses through chemical extraction. Produced through fermentation or chemical synthesis processes that isolate and concentrate the betaine compound.
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. 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. Betaine reduces plasma homocysteine levels in patients with homocystinuria. 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, and the EMA has approved the use of Amversio (betaine anhydrous, oral powder).
