Vitamin C is a water soluble vitamin necessary for the production of skin, tendons, ligaments, and blood vessels. It is essential for wound healing and for the repair of cartilage, bones, and teeth. Vitamin C is a powerful antioxidant and helps reduce free radicals that have been shown to contribute to cancer, heart disease, and the aging process. It is important to include plenty of Vitamin C containing food in your diet throughout the day.
