Product Overview

High purity L-Lysine HCl white crystalline powder with ≥98.5% purity for feed, food, and supplement applications.

L-Lysine Hydrochloride is the stable, readily soluble salt form of the essential amino acid L-Lysine. As an essential amino acid, it cannot be synthesized by the body and must be obtained through diet or supplementation . L-Lysine HCl plays a fundamental role in protein synthesis, collagen formation, calcium absorption, and immune function, making it indispensable for growth, recovery, and overall health in both humans and animals .

In animal nutrition, L-Lysine is recognized as the first limiting amino acid for pigs and the second limiting amino acid for poultry — meaning it is the most critical amino acid that must be supplemented in feed formulations to optimize growth performance and feed efficiency . Supplementing L-Lysine allows feed manufacturers to use lower-cost feed ingredients while maintaining desired growth rates and protein levels within livestock .

At Henan Liyin Biotech, we supply high-purity L-Lysine HCl in the form of a white crystalline powder, with a minimum purity of ≥98.5% (typically 98.5–101.5%), compliant with USP, EP, and FCC standards . Our product is available in Feed Grade, Food Grade, and Supplement Grade to serve applications across animal nutrition, human food, dietary supplements, and personal care.

Key Functional Properties

Protein Synthesis & Muscle Growth

L-Lysine is one of the most important amino acids for protein synthesis. It is incorporated into the structural proteins of muscles and supports growth as well as regeneration after physical exertion. As a primary component of muscle tissue, it is essential for maintenance and development of lean muscle mass .

Collagen Formation & Skin Health

L-Lysine is a critical component of collagen production — the structural protein that keeps skin, bones, tendons, and connective tissue firm and elastic. It activates enzymes that stabilize collagen structures, supporting wound healing, skin regeneration, and tissue repair .

Calcium Absorption & Bone Health

L-Lysine promotes the absorption of calcium in the intestines and its incorporation into bones. This supports bone density and helps maintain skeletal health, particularly important in combination with vitamin D and K2 for optimal bone metabolism .

Immune Support & Viral Defense

L-Lysine plays a role in the production of antibodies, strengthening the immune system. It inhibits the replication of the herpes simplex virus (HSV-1) by competing with the amino acid L-Arginine for cellular uptake — arginine is required by the virus for its replication. Therefore, L-Lysine is frequently used to help prevent herpes outbreaks or shorten their duration .

Carnitine Precursor & Energy Metabolism

L-Lysine is a precursor of L-Carnitine, an amino acid derivative needed for the normal metabolism of fatty acids for energy production in the body .

Stress Reduction & Mood Support

  1. Lysine has a calming effect on the central nervous system by modulating the stress response via cortisol levels. Studies show that, in combination with L-Arginine, it can help reduce anxiety and stress symptoms .

Quality Assurance & Documentation
