Your body needs iron to make a protein called hemoglobin. This protein is found in red blood cells. It carries oxygen from the lungs to the rest of the cells in your body. If you don't get enough iron, your body makes fewer and smaller red blood cells. As a result, your body's cells may not get enough oxygen.
Most people can get the iron their bodies need by eating enough iron-rich foods. Your doctor may advise you to take an iron supplement along with eating an iron-rich diet.
You can get iron from many foods. Beef and turkey are good sources of iron from meat. Beans are good sources of iron from plants. Some fortified cereals and grains are rich in iron. Ask your doctor or registered dietitian about how to be sure you are getting enough iron.
