DL-Methionine is widely used in animal feed as a nutritional supplement, particularly for poultry, swine, cattle, and aquaculture species like fish and shrimp. It serves as an essential amino acid that supports growth, improves feed efficiency, and enhances overall animal health. In poultry farming, it is crucial for feather development and egg production. Beyond animal nutrition, DL-Methionine is utilized in the pharmaceutical industry for the production of medications and supplements addressing amino acid deficiencies, liver disorders, detoxification (e.g., acetaminophen overdose), and supporting liver function and immune health in humans. It also finds application in cosmetics and personal care products as a conditioning agent to improve hair and skin health. In agriculture, it is sometimes used as a precursor for the synthesis of plant growth regulators. Additionally, it may be incorporated in food processing to enhance the quality of meat products.
