Iron is a mineral needed for optimal health. It’s important for healing and the immune system. It is also a part of hemoglobin, a protein in blood that carries oxygen from the lungs to the rest of the body. Low iron levels can cause you to feel tired, short of breath, and to be more susceptible to infection. Iron deficiency anemia can be related to low iron in your diet, poor absorption of iron in your body, or due to a medication or disease.
On the periodic table, iron is the symbol Fe, and in our bodies, it’s an essential mineral that helps blood carry oxygen and perform other critical functions.
