Iron (Fe)

Iron (Fe) is a mineral essential for human health, primarily because it helps produce hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. It also supports immune function and energy metabolism. Iron is found in various foods, especially in red meats, beans, spinach, and fortified cereals. The body absorbs iron to ensure adequate oxygen delivery, but both iron deficiency and excess can cause health issues. Maintaining a balanced intake is important for overall well-being.
