Understanding the Importance of Iron in the Body
Iron is an essential mineral that plays a critical role in maintaining overall health. It is a key component of hemoglobin, the protein in red blood cells responsible for transporting oxygen throughout the body. Without adequate iron, the body cannot produce enough healthy red blood cells, leading to conditions such as anemia, which is characterized by fatigue, weakness, and decreased immune function. Beyond oxygen transport, iron also supports muscle function, cognitive development, and energy production.
