About this supplement
Calcium ascorbate is a buffered form of vitamin C, which combines ascorbic acid with calcium. This form is less acidic than ascorbic acid alone, making it gentler on the stomach and suitable for individuals who may experience gastrointestinal discomfort from standard vitamin C supplements. It is used as an antioxidant and plays a crucial role in collagen synthesis, immune function, and the absorption of iron from plant-based foods.
