General Statements: All Other Content
Calcium ascorbate is non-acidic (pH neutral), making it gentle on the digestive system. Vitamin C plays a vital role in the formation of collagen (a structural protein in connective tissue), amino acid metabolism and hormone synthesis, and the utilization of many nutrients, such as folic acid and iron. It is also a key factor in the body’s immune system.
