Iron is an essential mineral for oxygen transport in the blood. It is a key component of hemoglobin, the protein in red blood cells that binds oxygen and facilitates its delivery to tissues throughout the body. Adequate iron levels are crucial for maintaining energy levels and overall vitality, especially in physically active individuals and athletes. Insufficient iron can lead to anemia, resulting in fatigue, weakness, and decreased performance. Ensuring sufficient dietary intake of iron-rich foods is vital for overall health.
