Vitamins such as A, B (there are several), C, D and E, and minerals, like calcium, iron and sodium, are needed by the body to trigger chemical reactions necessary to maintain good health. Vitamins enhance the body’s use of carbohydrates, proteins and fats and are critical in the formation of blood cells, hormones, nervous system chemicals known as neurotransmitters, and DNA. Minerals are small amounts of metallic elements that are vital for the healthy growth of teeth and bones. They also help in such cellular activities as enzyme action, muscle contraction, nerve reaction, and blood clotting.
Most Americans do not eat a balanced, nutritious diet, and, therefore, are not getting enough vitamins and minerals. For this reason, it is suggested that most people supplement their diet with high quality vitamins to ensure proper levels are consumed.
