DL-Methionine is widely used in animal feed as a nutritional supplement, particularly for poultry, swine, and cattle. It serves as an essential amino acid that supports growth, improves feed efficiency, and enhances overall animal health. In aquaculture, it is added to fish feed to promote healthy growth and development. Additionally, DL-Methionine is utilized in pet food to ensure balanced nutrition for cats and dogs. Beyond animal nutrition, it plays a role in pharmaceuticals, where it is incorporated into formulations for liver health and detoxification. It is also used in cosmetics and personal care products for its antioxidant properties, helping to protect skin from oxidative stress.
