calcium ascorbate

Calcium ascorbate is a mineral ascorbate and a buffered form of vitamin C in which the ascorbic acid (vitamin C) is combined with calcium. It is used to prevent or treat vitamin C deficiency and provides both vitamin C and supplemental calcium[1][2][5]. As an antioxidant, it helps protect cells from oxidative damage and supports immune function. The addition of calcium makes this form less acidic than pure ascorbic acid, making it gentler on the stomach for those sensitive to acidity[1]. Calcium ascorbate is commonly used in dietary supplements for general health maintenance and to support skin, cartilage, teeth, bone health, blood vessels integrity, wound healing processes, iron absorption from plant foods (non-heme iron), and immune system function[1][4]. It may also be included in combination products for enhanced pain relief or immune support[5].
