Palafer Iron Supplement (Ferrous Fumarate) may be recommended to take if you have low blood levels of iron. Without iron, your body is not able to produce enough hemoglobin; the part of red blood cells that bind and carry oxygen in your blood. This can cause you to feel tired, have shortness of breath, and could increase the risk of an infection. By including more lean red meat, chicken, turkey, and fish to your diet you may improve your levels of iron in your body. If you are vegetarian, you can include more legumes, lentils, beans/peas, and nuts or seed that have high levels of iron so you do not become anemic.
