Iron is crucial for oxygen transport and energy production because it helps form hemoglobin, the protein in red blood cells that carries oxygen throughout the body. While iron is essential for preventing anemia and supporting overall vitality, it is not the mineral responsible for maintaining bone health. Unlike calcium, which provides structural integrity to bones and teeth, iron serves a completely different function. A deficiency in iron can lead to fatigue, weakness, and decreased immune function, but it does not directly contribute to bone strength or density. Confusing iron with calcium may cause someone to neglect the nutrients most vital for skeletal health. To properly support bones, calcium should be the mineral you focus on.
