The Active Ingredient Is: Vitamin C (Calcium Ascorbate)

Vitamin C, also called ascorbic acid, is a water-soluble vitamin crucial for everyday bodily functions.

This buffered version uses calcium ascorbate, a mild neutral-pH pick friendly to sensitive stomachs.

What Does Vitamin C (Calcium Ascorbate) Do?

Vitamin C helps to shield cells against oxidative stress by acting as an antioxidant and supports everyday immune function.

It contributes to collagen production for skin, blood vessels and joints, and the buffered form gives gentler gastric comfort.
