Other names: Trimethylglycine, Abromine

Harm score: 2 (Derivatives of natural substances)

Betaine (Glycine), also known as Trimethylglycine or Abromine, is an amino acid that occurs naturally in some foods such as spinach, cereals and seafood. Betaine is an important component of many biological processes, including amino acid and protein metabolism. It is also a key factor in the process of methylation, a biological process necessary for many different cellular functions, from DNA repair to energy production.

As a dietary supplement, betaine is widely used to support heart, kidney and liver health. By incorporating it into diets, betaine has the ability to lower homocysteine levels in the blood, which may reduce the risk of heart disease. In addition, betaine is included in some cosmetic products where it acts as a humectant to help maintain moisture in the skin and hair. Due to its properties, it is also used in the animal feeding industry and in some cases is used as an additive in food and beverages to improve taste and consistency.
