Description

L-Lysine L-Malate is a high-purity, crystalline salt formed from the essential amino acid L-Lysine and L-Malic acid. This compound is valued for its role as a bioavailable source of L-Lysine, offering enhanced stability and handling characteristics compared to the free amino acid. It serves as a critical functional ingredient for manufacturers in the nutraceutical, food fortification, and animal nutrition industries seeking to improve protein quality and support metabolic functions.

Application

• Dietary Supplements & Nutraceuticals: A key ingredient in amino acid supplements, protein powders, and wellness products to support muscle protein synthesis, immune function, and overall health.
• Food & Beverage Fortification: Used to enrich cereals, baked goods, beverages, and meal replacements, addressing lysine deficiencies in plant-based diets and improving the protein efficiency ratio.
• Animal Feed & Pet Nutrition: An essential additive in premixes for poultry, swine, and aquaculture feeds to optimize growth performance, feed efficiency, and lean muscle development.
• Pharmaceutical Intermediates: Serves as a starting material or chiral building block in the synthesis of more complex pharmaceutical compounds and active ingredients.
• Cosmetic & Personal Care: Incorporated into hair care and skin care formulations for its potential moisturizing and conditioning properties.
• Microbiological & Cell Culture Media: Used as a defined nutrient component in fermentation media and cell culture systems for the production of biologics, enzymes, and other fine chemicals.

Quality Control

Our L-Lysine L-Malate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for food, feed, and nutraceutical applications. Certificates of Analysis (COA) documenting key parameters such as assay, optical rotation, and impurity profiles are provided to guarantee traceability and batch-to-batch consistency.

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 original container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
