What are vitamins?
Vitamins are substances which, in small amounts, are necessary to sustain life. They must be obtained from food as they are either not made in the body at all, or are not made in sufficient quantities for growth, vitality and wellbeing. Lack of a particular vitamin or mineral can lead to incomplete metabolism, fatigue and other health problems; and in severe cases, to deficiency disease. A deficiency of a particular vitamin causes disease symptoms which can only be cured by that vitamin.
Vitamins are chemically unrelated substances and are all organic. Organic substances are those that contain carbon and come from materials that are living, such as plants and animals; or that were once living, for example, petroleum or coal. It is impossible to sustain life without all the essential vitamins.
