Vitamin C is also known as ascorbic acid - a micronutrient that best

body tissues such as skin, bones, tendons, muscles and cartilage, enhances iron
absorption, and prevents cataracts. Vitamin C is also known to be an
antioxidant, which helps protect cells from free radical damage. Free radical
cell damage causes cardiovascular disease, cancer and other chronic diseases.
