Product Description
Calcium Ascorbate is a calcium salt of ascorbic acid (vitamin C), formed by combining ascorbic acid with calcium carbonate. This compound is a pH-neutral, buffered form of vitamin C, offering both the antioxidant benefits of ascorbic acid and the mineral calcium. It is widely used in food, pharmaceuticals, and dietary supplements due to its stability, bioavailability, and gentle nature on the digestive system.
Key Features:
Buffered & Non-Acidic: Unlike pure ascorbic acid, calcium ascorbate is pH-neutral, making it less irritating to the stomach and suitable for individuals with acid sensitivity.
Dual Nutrient Source: Provides bioavailable vitamin C (antioxidant, immune support) and calcium (bone health, muscle function) in a single compound.
High Stability: Resists oxidation better than pure ascorbic acid, especially in aqueous solutions, extending shelf life in formulated products.
Water-Soluble: Easily dissolves in water, ideal for beverages, effervescent tablets, and liquid supplements.
Antioxidant Properties: Protects foods and cosmetic formulations from oxidative damage, preserving color, flavor, and nutrient content.
Safety & Compliance: Approved by regulatory agencies (e.g., FDA, EFSA) as a food additive (E302) and dietary supplement ingredient.
