DL-Methionine CAS 59-51-8

DL-Methionine is supplied as a nutritional amino acid for feed applications, primarily used in livestock and poultry formulations to balance amino acid profiles and support growth performance. As an essential sulfur-containing amino acid, it is commonly incorporated into compound feeds where natural protein sources may be deficient in methionine.

It is typically used in premixes, concentrates, and complete feed formulations for poultry, swine, and aquaculture. DL-Methionine is generally supplied as a crystalline powder or granulated form suitable for uniform mixing in feed processing systems. Standard packaging, bulk supply, and documentation such as COA, TDS, and SDS are available to support feed industry procurement.
