Vitamin C is an antioxidant vitamin essential to the body's health and is especially important for maintaining healthy skin, but unlike most other animals, humans cannot make their own vitamin C.
It is also known as ascorbic acid and is a water-soluble vitamin.
With vitamin C playing a role in being part of more than 300 bodily functions, life itself depends on daily replenishment.
Its primary function is to maintain collagen, a protein necessary for the formation of skin, ligaments, bones and teeth, and for the strength of blood vessel walls.
In addition, vitamin C plays an important part in the absorption of iron, which is necessary for the formation of red blood cells.
It also plays a role in the utilisation of folic acid, one of the B-complex vitamins.
