Used primarily in the animal feed industry as a dietary supplement to enhance the methionine content in livestock nutrition, promoting growth and improving overall health. It is particularly beneficial in poultry and swine diets, where methionine is often a limiting amino acid. Additionally, it serves as a precursor for the synthesis of proteins and other essential biomolecules, supporting metabolic functions. In some cases, it is also employed in research settings to study amino acid metabolism and its impact on animal physiology.
