According to the National Institutes of Health, vitamin C is a water-soluble vitamin that is essential for humans, helping tissues and cells to grow properly and repair themselves. Vitamin C is also an antioxidant and can prevent free radicals from damaging cells in the body. Additionally, the vitamin boosts the immune system.
Vitamin C is necessary for the replication and repair of cells throughout the body. It is used to form the vital proteins that comprise the skin, tendons, blood vessels and ligaments in the body, states the National Institutes of Health. The vitamin also helps the body heal quickly and maintain cartilage, teeth and bones. Since the vitamin is an antioxidant, it can also help people appear youthful by preventing the buildup of free radicals in the body. Free radicals also play a role in cancer development and heart disease. Therefore, vitamin C may help prevent these diseases.
