|What are food supplements?|
Food supplements include tablets, capsules, powders, liquids and a wide variety of other forms which are taken for their health-giving properties. They are composed of micronutrients, such as vitamins and minerals, and a range of other substances such as amino acids, fatty acids, plants and extracts of plants.
|Why do people take supplements?|
Hundreds of millions of people around the world take supplements regularly for a range of different reasons, but the main one is to maintain good health. Many people take food supplements as a form of "health insurance", to ensure that they get an adequate intake of nutrients. With the growing body of scientific evidence that supports the potential benefits of taking higher levels of certain nutrients, people also take supplements to prevent the risk of certain illnesses and diseases.
|What are the benefits of supplements? Is there proof that supplements work?|
Many studies have already been carried out to establish the benefits of food supplements. Antioxidants, for example, may have a protective effect against free radicals in the body which cause damage to body cells. They may therefore be especially important in protecting against human diseases associated with free radical damage to cellular DNA, lipids and proteins. These diseases include cardiovascular diseases, coronary heart disease and cancer.
|What are antioxidants?|
Certain vitamins are classed as antioxidants. Antioxidants are naturally present in the body and are known to combat the damaging free radicals in our body. Antioxidants include the vitamins A, C, and E and the mineral selenium as well as a range of plant and other ingredients.
