    Many brands of vitamins are sold at chemists and supermarkets, but most people know very little about them.

    The vitamin industry

    There are over 85,000 vitamin products and dietary supplements available. Almost one billion people take vitamin tablets, and the world market is worth about $100 billion.

    Vitamin C

    Vitamin C, also known as ascorbic acid, is found in citrus fruits, kiwi fruits, red capsicums, tomatoes and strawberries. Eating fresh fruit and vegetables regularly will supply the daily vitamin C need for most people.

    It is widely believed to be a cure for the common cold. Although this is not proven, there is evidence that it does help to strengthen the immune system, and even helps prevent skin wrinkling.

    Vitamin D

    Vitamin D is essential for absorbing calcium. You can get vitamin D from sunlight, but you also need to guard against harmful UV rays. The best time of day is between 11am and 1pm.

    Foods containing vitamin D include tuna, mackerel, salmon, egg yolks and some dairy products.

    The vitamin D in most supplements comes from lanolin, a mixture of fatty acids in the greasy wool of sheep.

    Vitamin breakdown

    Nutrition tables show the vitamin quantity in fresh foods, not foods that have been stored. Vitamins break down very quickly as food ages, because of heat, light, and storage conditions. For example, 75% of the vitamin C in an apple can be lost in one week.

    Over-use

    It is possible to take too many vitamins and become ill as a result. Fat soluble vitamins A, D, E and K are stored in our liver and fatty tissues. If you take too much, they can build up to toxic levels. This is especially dangerous for small children.

    Synthetic materials

    Most vitamins in tablet or capsule form are produced in chemical factories. They are chemically identical to the natural form, but don’t have the fibre and other nutrients in fresh food. At least eight vitamins contain components which are also found in nail polish remover, petrol and bitumen.
