Iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. Without enough iron, the body cannot produce an adequate amount of healthy red blood cells, leading to a condition called iron-deficiency anemia. Symptoms of iron deficiency anemia include fatigue, weakness, and impaired cognitive function.
