liposomal L-Lysine 80% — High Bioavailability Essential Amino Acid Supplement

Product Overview

Liposomal L-Lysine 80% is a premium-grade dietary supplement ingredient delivering L-lysine in an advanced liposomal delivery system. L-Lysine (CAS 56-87-1), also known as (2S)-2,6-diaminohexanoic acid or α,ε-diaminocaproic acid, is an essential proteinogenic α-amino acid with the molecular formula C₆H₁₄N₂O₂ and a molecular weight of 146.19 g/mol. It is a white to light yellow crystalline powder or crystals that is freely soluble in water (100 mg/mL). L-Lysine is one of the nine essential amino acids in humans and is a basic amino acid containing two amino groups and one carboxyl group.

L-Lysine is found in high-protein foods including meat, poultry, fish, dairy products, eggs, and legumes. It is particularly important as a precursor for carnitine synthesis, which is required for fatty acid transport into mitochondria for energy production. L-Lysine also plays a critical role in the biosynthesis of collagen and elastin, and enhances the absorption of calcium by the intestine, making it valuable for bone health.

Why Liposomal Technology?

Conventional L-lysine presents significant formulation challenges. Free L-lysine is extremely hygroscopic, easily deliquesces, and is susceptible to yellowing and deterioration due to its free amino groups, with a stimulating fishy smell that makes it difficult to store long-term. Additionally, L-lysine competes with other amino acids for transport across the intestinal epithelium.

Liposomal encapsulation provides four critical advantages:

1. Enhanced Stability — The phospholipid bilayer shields L-lysine from moisture absorption and oxidative degradation, preventing the yellowing and deterioration that occurs with free L-lysine. Liposomal encapsulation locks in ambient stability and significantly optimizes ingredient dispersion.

2. Enhanced Absorption and Bioavailability — Liposomal encapsulation protects L-lysine from premature metabolism in the gastrointestinal tract and facilitates efficient cellular uptake via lipid-mediated pathways. This delivery mechanism complements the amino acid transport pathways utilized by free L-lysine.

3. Sustained Release for Balanced Amino Acid Support — Liposomal delivery provides a sustained-release profile that maintains steady plasma amino acid levels, supporting balanced physiological effects rather than a sharp peak followed by rapid decline. Amino acids are best absorbed when taken half an hour before eating or sleeping.

4. Water-Dispersible Formulation — Liposomal L-lysine powder offers excellent dispersibility in water, forming a uniform suspension suitable for functional beverages and liquid formulations.

Product Specifications

Key Features

• High Purity — Standardized to ≥80% L-lysine, with pharmaceutical-grade assay of 97.0%–103.0% on anhydrous basis available.

• Liposomal Enhancement — Phospholipid bilayer encapsulation protects L-lysine from moisture absorption and oxidative degradation, enhancing stability and intestinal absorption through lipid-mediated pathways.

• Immune Support — L-Lysine helps reduce the recurrence of herpes simplex virus (HSV) infection, including cold sores. It may slow or stop the growth of viruses and protect against sexual transmission of the herpes virus.

• Collagen Formation — L-Lysine is essential for the biosynthesis of collagen and elastin, supporting skin, joint, and connective tissue health.

• Calcium Absorption — L-Lysine enhances intestinal calcium absorption, contributing to bone health and the treatment of osteoporosis.

• Clinically Studied for Morbidity Reduction — Supplementation in children reduced diarrheal episodes, and men had fewer coryza episodes in a Ghana study.

• Water-Dispersible — Freely soluble in water (100 mg/mL); suitable for capsules, tablets, powder drink mixes, and functional beverages.

• Batch Traceability — Complete COA, HPLC chromatogram, and identity data provided for each batch.

Application & Formulation Guidance

Recommended Dosage

Clinical studies and commercial products commonly recommend 500–3,000 mg of L-lysine per day, depending on the intended use. For general health support, 500–1,500 mg daily is commonly recommended. Doctors often suggest that people with recurrent herpes simplex infections take 1,000–3,000 mg of lysine per day. The optimal dosage of L-lysine for prophylaxis against relapsing herpes simplex is not yet well defined, with doses ranging between 500 and 3,000 mg daily. The World Health Organization recommends approximately 30 mg per kilogram of body weight daily for lysine intake from all sources. Amino acids are best absorbed when taken half an hour before eating or sleeping. Liposomal formulations may allow for more efficient utilization of lower doses due to enhanced bioavailability.
