What the brand says

Vitamin C, also referred to as ascorbic acid, is the single most commonly used vitamin supplement. It plays a major 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 natural defenses. The suggested use is to take 1 tablet 1 to 2 times daily. Please contact our in-house customer support if you have any questions.
