Vitamin C is an essential dietary component in a healthy diet. Since water-soluble vitamin C is not stored in the body, it must be replenished daily. Vitamin C is an essential nutrient necessary for the formation of collagen, a fibrous protein present in bone, tendons, ligaments, cartilage and connective tissues of skin and blood vessels. Daily requirements of vitamin C increase with age as the need to regenerate collagen increases. Vitamin C helps support the immune system and helps prevent iron-induced oxidation due to its antioxidant properties. It systematically interacts with other nutrients to provide maximum nutritional benefits.
