What Is Iron?
Iron is an essential mineral your body needs to produce hemoglobin — the protein in red blood cells that carries oxygen throughout your body. Without enough iron, your cells don’t get the oxygen they need, leading to fatigue, weakness, and low energy.
Iron deficiency is one of the most common nutrient deficiencies in the world.
