PHARMACOLOGICAL ACTION: Dietary supplementation. Vitamin C or ascorbic acid is a water soluble vitamin easily lost to the body and unstable, being sensitive to light and air. Illness, diet, drugs, cooking and modern food processing destroy it and supplementation for nutritional support may then be required.
Ascorbic acid functions in a number of metabolic reactions such as collagen synthesis of teeth and bones.
Recent research indicates that ascorbic acid plays an essential role in fighting infection.
