What is the consequence of low iron levels in the body?

Low iron levels in the body significantly impair oxygen transport to cells. Iron is a crucial component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. When iron levels are insufficient, hemoglobin production decreases, leading to lower oxygen availability. This can result in symptoms such as fatigue, weakness, and shortness of breath, which are characteristic of iron deficiency anemia. The ability of cells to function optimally is reliant on adequate oxygen, making it vital for overall health and energy levels.

While options related to energy production, immune function, and metabolism are important in their own rights, low iron levels primarily compromise the oxygen-carrying capacity of the blood, leading to broader effects on health and vitality.
