  • Applications

    L-Lysine sulfate is primarily used as a source of the essential amino acid L-lysine in animal nutrition, serving as a feed additive for poultry, swine, and other livestock to support protein synthesis. It is also used in human nutrition and food fortification as a lysine supplement where permitted by regulation. In pharmaceutical and clinical nutrition, it may be employed as a lysine source in parenteral nutrition solutions and other amino acid formulations. In biotechnology and industrial bioprocessing, it can act as a nutrient and starting ingredient in fermentation media for microbial production. Additionally, as a chemical input, it serves as a raw material or intermediate for the synthesis of lysine derivatives and peptide-building blocks. Usage is subject to local regulations and formulation limits.
