A healthy dose of Vitamin C protects our body from infections and maintains healthy bones and teeth. It also improves our body’s ability to repair wounds and keeps us immune from bacteria, viruses and infection. Not only is it a well-known component of our immune system, it is also necessary for collagen, the main structural protein found in connective tissue. Vitamin C, taken orally, helps wounds heal faster and better. Applied topically, it protects the skin from free radical damage from the exposure to UV rays.
