High Purity Sodium Ascorbate USP - Antioxidant Vitamin C for Supplement Formulations
Vitamin C is one of the most essential nutrients for human health, playing critical roles in immune function, collagen synthesis, antioxidant protection, and iron absorption. However, standard ascorbic acid can be acidic and potentially irritating to sensitive digestive systems. High Purity Sodium Ascorbate USP offers a superior, pH-neutral form of vitamin C that delivers all the benefits of this vital nutrient with enhanced bioavailability and gentler gastrointestinal tolerance. This pharmaceutical-grade ingredient is specifically designed for premium dietary supplements, functional foods, and nutraceutical applications where purity, stability, and efficacy are paramount.
Key Advantages of High Purity Sodium Ascorbate USP
Exceptional Purity & Quality Compliance
Manufactured to meet stringent USP (United States Pharmacopeia) standards, this sodium ascorbate guarantees >99% purity with minimal impurities. It undergoes rigorous testing for heavy metals, microbial contamination, and other quality parameters to ensure safety for human consumption.pH-Neutral & Gentle on Digestion
Unlike acidic ascorbic acid, sodium ascorbate is buffered and non-irritating to the stomach lining, making it ideal for sensitive individuals or high-dose supplementation programs. This characteristic also enhances compliance in pediatric and geriatric formulations.Superior Bioavailability
The sodium ascorbate form demonstrates excellent water solubility and absorption kinetics in the gastrointestinal tract, ensuring efficient uptake and utilization by the body. Studies suggest comparable or better bioavailability than standard ascorbic acid.Powerful Antioxidant Protection
As one of nature's most effective water-soluble antioxidants, sodium ascorbate neutralizes free radicals throughout the body's aqueous compartments, protecting cells from oxidative damage linked to aging, inflammation, and chronic disease.Multi-Functional Health Support
Beyond its antioxidant properties, this ingredient supports:-
Immune function by enhancing leukocyte activity and interferon production
Collagen formation for skin, joint, and vascular health
Iron absorption through reduction of ferric to ferrous iron in the gut
Neurotransmitter synthesis including norepinephrine and carnitine
-
Applications in Nutraceutical Products
