What is L-Ascorbic Acid?

L-Ascorbic Acid (vitamin C) is a natural, water-soluble vitamin. It is an essential nutrient for the human body, but humans cannot synthesize it on their own and must supplement it through diet or topical application. As the only biologically active form of vitamin C, L-ascorbic acid plays a central role in antioxidant, collagen synthesis and immune regulation. XJESON L-Ascorbic Acid Powder is a premium bioactive form of Vitamin C, meticulously synthesized to achieve ≥99.9% HPLC-verified purity, ideal for global B2B clients in pharmaceuticals, cosmetics, and functional food industries. As the only biologically active isomer of Vitamin C, L-ascorbic acid (LAA) is renowned for its unparalleled antioxidant properties, collagen-boosting capabilities, and critical role in immune support25. Our powder combines cutting-edge microencapsulation technology with global compliance (USP, EP, ISO 22000) to ensure stability, bioavailability, and seamless integration into diverse formulations.
