L-Lysine Hydrochloride CAS#657-27-2
Supports Growth & Protein Synthesis – Essential for protein production, L-Lysine promotes proper growth and contributes to maintaining muscle and bone health.
Enhances Nutrient Absorption & Cholesterol Control – Helps the body absorb calcium, zinc, and iron efficiently while lowering cholesterol levels through carnitine production.
Immune & Antiviral Benefits – Competes with arginine during viral replication, reducing herpes simplex virus infection and supporting immune defense.
Wellness & Medical Applications – Used by athletes for lean mass building, helps reduce chronic anxiety, and improves the properties of serum albumin solutions for injections.
L-Lysine is an essential amino acid required by both humans and animals. It plays a vital role in protein synthesis and supports healthy growth. By promoting carnitine production, L-Lysine helps lower cholesterol levels. It also enhances the absorption of essential minerals such as calcium, zinc, and iron. Athletes often use L-Lysine as a supplement to build lean muscle mass and maintain strong bones and muscles. Additionally, L-Lysine competes with arginine during viral replication, thereby reducing herpes simplex virus infections. Supplementation with L-Lysine has also been shown to alleviate chronic anxiety in humans. Furthermore, it decreases the viscosity of serum albumin solutions used in injections.
