                                According to the World Health Organization, iron deficiency is the most common nutritional disorder globally. If you have no iron, your body cannot produce enough hemoglobin, a protein in red blood cells that transports oxygen, leading to a serious medical condition called iron deficiency anemia. This can trigger a cascade of severe health issues affecting your heart, brain, and immune system.
