Product Description

Product Description

Ascorbic Acid, commonly known as Vitamin C, is a water-soluble vitamin and a potent antioxidant essential for human health. Naturally found in citrus fruits, berries, and leafy greens, it is commercially produced through fermentation (using glucose and microbial strains) or chemical synthesis. Ascorbic acid is widely used in food, pharmaceuticals, cosmetics, and industrial applications due to its antioxidant, pH-regulating, and collagen-synthesis-boosting properties. It complies with USP, BP, EP, FDA GRAS, and EU food additive (E300) standards.

Key Features

Antioxidant Power: Neutralizes free radicals, preventing oxidative damage in food and biological systems.
Nutrient Fortification: Restores or enhances vitamin C content in processed foods and supplements.
Acidity Regulator: Lowers pH in beverages and preserves color in fruits and vegetables.
Collagen Production: Critical for skin health, wound healing, and connective tissue repair.
Natural & Synthetic Forms: Available as L-ascorbic acid (natural isomer) or sodium/calcium ascorbate for pH-sensitive applications.
