L-Lysine Monohydrochloride - Feed Ingredient

L-Lysine Monohydrochloride is a crystalline, water-soluble amino acid compound with the chemical formula C₆H₁₄N₂O₂·HCl. It is the hydrochloride salt of the essential amino acid L-lysine and appears as a white to slightly yellowish powder. This form is commonly used in feed and food applications due to its stability and high bioavailability.

In animal nutrition, including equine feed, L-lysine monohydrochloride is used as a supplemental source of lysine—an essential amino acid that must be supplied through the diet, as it cannot be synthesized by the animal. Lysine plays a role in protein synthesis and is often the first limiting amino acid in cereal-based diets.

The compound is typically added to feed formulations to help meet established lysine requirements, particularly in diets where natural lysine levels may be insufficient. It is used to support balanced amino acid profiles in feeds designed for growth, maintenance, or performance.

The following equine feeds, supplements and products contain L-Lysine Monohydrochloride as an ingredient.
