DL-Methionine is the racemic form of the essential sulfur-containing amino acid methionine, comprising equal parts of D- and L-isomers. It is one of the most important feed-grade amino acids globally. It serves as the first limiting amino acid in poultry diets.

In food applications, DL-Methionine is used for nutritional fortification and as a flavoring agent. It is produced through chemical synthesis from acrolein, methyl mercaptan, and hydrogen cyanide under controlled industrial processes. Its high bioavailability and cost-effectiveness make it an indispensable ingredient in modern animal nutrition and food manufacturing.
