C Vit Chew is a brand of ascorbic acid and sodium ascorbate. Antioxidants are molecules that interact with free radicals and terminate the chain reaction they cause before vital molecules are damaged. Without antioxidants our bodies would rust from the inside out, in a way similar to how metal rusts after exposure to a barrage of salt or the elements. Vitamin C is mainly necessary for cell mediated immune responses including leucocyte and macrophage functions, neutrophil motility and phagocytosis, but also for antimicrobial activity, interferon synthesis and antihistamine properties. It has been used to treat vitamin C deficiency, scurvy, delayed wound and bone healing, urine acidification, and in general as an antioxidant.
