A product containing one or more vitamins, herbs, enzymes, amino acids, or other ingredients, that is taken orally to supplement one's diet, as by providing a missing nutrient. Common supplements include vitamins, minerals and herbal products, also known as botanicals. People take these supplements to make sure they get enough essential nutrients and to maintain or improve their health.
Most people do not need to take Health Supplements and can get all the vitamins and minerals they need by eating a healthy, balanced diet. Vitamins and minerals, such as iron, calcium and vitamin C, are essential nutrients that your body needs in small amounts to work properly.
