Vitamin C is a water-soluble vitamin that supports the formation of collagen for the normal function of bones, cartilage, skin, teeth, gums and blood vessels. It also helps the body absorb iron.

Vitamin C is a powerful antioxidant and has been shown to reduce the duration of the common cold, and to reduce the risk of developing a cold when in extreme conditions (e.g. endurance athletes, subarctic soldiers, etc.) It furthermore contributes to maintain the normal function of the immune system during and after intense physical exercise.
