Covita Plus Capsule contains vitamin E and vitamin C. 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. Vitamin E is a dietary supplement which has cardio-protective activity and also used for treating diabetes and its complications. It is used for preventing cancer particularly lung and oral cancer in smokers; colorectal cancer and polyps; and gastric prostate and pancreatic cancer. Use under medical supervision.
