Vitamins are organic substances (made by plants or animals), minerals are inorganic elements that come from the earth; soil and water and are absorbed by plants. Animals and humans absorb minerals from the plants they eat. Vitamins and minerals are nutrients that your body needs to grow and develop normally.
Vitamins and minerals, have a unique role to play in maintaining your health. For example Vitamin D helps your body absorb the amount of calcium (a mineral) it needs to form strong bones. A deficiency in vitamin D can result in a disease called rickets (softening of the bones caused by the bodies inability to absorb the mineral calcium.) The body cannot produce calcium; therefore, it must be absorbed through our food. Other minerals like chromium, copper, iodine, iron, selenium, and zinc are called trace minerals because you only need very small amounts of them each day. The best way to get enough vitamins is to eat a balanced diet with a variety of foods. You can usually get all your vitamins from the foods you eat.
Many products are marketed as dietary supplements. It is important to remember that supplements include vitamins and minerals, as well as herbs, botanicals and other substances.
