3.1 Introduction Vitamins are classically defined as a group of organic compounds required in very small amounts for the normal development and functioning of the body. They are not synthesised by the body, or only in insufficient amounts, and are mainly obtained through food (Machlin and Huni, 1994). There are thirteen vitamins: four are fat-soluble, namely vitamins A (retinol)
