Description

L-Lysine Sulphate is an essential amino acid salt, widely recognized for its critical role in protein synthesis and metabolic functions. This high-purity compound is vital for formulating balanced nutritional supplements and enhancing the protein quality of animal feed. It is a fundamental raw material for manufacturers in the animal nutrition, pharmaceutical, and food fortification industries seeking reliable, bioavailable lysine sources.

Application

• Animal Feed Additive: Primary application as a limiting amino acid in swine, poultry, and aquaculture diets to optimize growth performance and feed efficiency.
• Human Nutritional Supplements: Key ingredient in protein powders, amino acid blends, and dietary supplements to support muscle health and overall wellness.
• Food Fortification: Used to enrich cereals, baked goods, and meal replacements, addressing lysine deficiencies in staple foods.
• Pharmaceutical Intermediates: Serves as a chiral building block in the synthesis of active pharmaceutical ingredients (APIs) and peptide drugs.
• Microbial Culture Media: Essential nutrient component in fermentation processes for the production of antibiotics, enzymes, and other biologics.
• Cosmetic Formulations: Incorporated into hair and skin care products for its purported moisturizing and conditioning properties.

Quality Control

Our L-Lysine Sulphate is produced under a stringent quality management system. Each batch is tested to ensure it meets high-purity standards suitable for feed, food, and pharmaceutical applications. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available for every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption.
