Description

Zinc-L-Ascorbat CAS NO 151728-40-4 is a stable, bioavailable complex of zinc and L-ascorbic acid (Vitamin C), offering the combined benefits of both essential nutrients. This compound is valued for its enhanced stability and synergistic antioxidant and immune-supporting properties compared to its individual components. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and functional food and beverage industries for formulating high-quality dietary supplements and fortified products.

Application

• Dietary Supplements: A key ingredient in tablets, capsules, and powders for immune support, antioxidant protection, and skin health formulations.
• Functional Foods & Beverages: Used to fortify products like nutritional drinks, health bars, and dairy alternatives with bioavailable zinc and Vitamin C.
• Cosmetic & Personal Care: Incorporated into topical creams, serums, and lotions for its antioxidant and potential skin-brightening properties.
• Pharmaceutical Preparations: Utilized in specific medicinal products where the combined action of zinc and ascorbate is therapeutically beneficial.
• Animal Nutrition (Feed Additives): Applied in premium pet food and livestock feed to support animal health, immunity, and overall well-being.
• Research & Development: Serves as a critical reagent in biochemical and nutritional studies investigating mineral-ascorbate interactions.

Quality Control

Our Zinc-L-Ascorbat is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for nutraceutical and food-grade applications. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, heavy metals, and microbiological limits. Specifications can be aligned with relevant industry guidelines such as FCC and USP upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 moisture absorption and degradation. For long-term storage, consider using desiccants or storing under an inert atmosphere to minimize oxidation.
