Description

L-Lysine L-Ascorbate is a stable, water-soluble compound formed from the essential amino acid L-Lysine and the antioxidant vitamin C (L-Ascorbic Acid). This synergistic combination offers enhanced stability and bioavailability compared to ascorbic acid alone, making it a valuable functional ingredient. It is primarily utilized in the pharmaceutical and nutraceutical industries for its dual role in supporting collagen synthesis and immune function, as well as in premium food and cosmetic formulations.

Application

• Pharmaceutical & Nutraceutical Formulations: Used as a stable source of Vitamin C and L-Lysine in tablets, capsules, and effervescent powders for dietary supplements and therapeutic products.
• Functional Food & Beverage Fortification: Incorporated into health drinks, sports nutrition products, and fortified foods to enhance nutritional value and antioxidant content.
• Cosmetic & Skincare Products: Acts as an active ingredient in anti-aging serums, creams, and lotions for its role in collagen production and skin brightening.
• Animal Feed Additive: Employed in premium pet food and livestock nutrition to support immune health and overall vitality.
• Biochemical Research: Serves as a reagent or standard in laboratory studies related to amino acid metabolism and antioxidant mechanisms.

Quality Control

Our L-Lysine L-Ascorbate is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. We provide comprehensive Certificates of Analysis (COA) that include testing for identity, assay, related substances, and residual solvents, referencing methodologies from major pharmacopoeias such as USP and EP.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
