Description

L-Lysine Citrate is a high-purity, water-soluble salt formed from the essential amino acid L-Lysine and citric acid. This compound is valued for its enhanced stability and bioavailability compared to the free amino acid, making it a critical ingredient in formulations requiring precise nutritional fortification. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and food and beverage industries to develop products that support metabolic function and overall health.

Application

• Pharmaceutical Formulations: Used as an active pharmaceutical ingredient (API) or excipient in injectable solutions, tablets, and capsules for amino acid supplementation and metabolic support.
• Dietary Supplements & Nutraceuticals: A key component in protein powders, sports nutrition products, and general health supplements to ensure adequate lysine intake.
• Food & Beverage Fortification: Employed to enrich cereals, baked goods, and beverages, addressing nutritional deficiencies and enhancing the protein quality of food products.
• Animal Feed & Veterinary Products: Incorporated into premixes and medicated feeds to promote growth, improve feed efficiency, and support immune function in livestock and pets.
• Cell Culture Media: Serves as a defined nutrient source in microbiological media and bioprocessing applications for the cultivation of cells and microorganisms.
• Cosmetic & Personal Care: Used in skincare formulations for its potential role in collagen synthesis and as a pH buffer.

Quality Control

Our L-Lysine Citrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets specifications for identity, purity, and composition. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, optical rotation, and impurity profiles. Production can be aligned with relevant standards including USP, FCC, and Ph. Eur. upon request, ensuring suitability for pharmaceutical, food, and feed applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
