  • Applications

    Lysine hydrochloride, DL- is widely used as a nutrient supplement for animal feeds to supply essential lysine in poultry and livestock diets. In pharmaceuticals and medical nutrition, it serves as a source of essential amino acids for parenteral nutrition formulations and oral supplements. In food processing, it can be used as a nutritional fortificant in fortified foods and beverages where lysine supplementation is desired. In biotechnological and laboratory settings, it is used as a component of defined cell culture media and fermentation media to provide lysine for cell growth. In industrial manufacturing, it can serve as a feedstock or precursor for lysine-derived polymers and related chemical syntheses.
