Iron is a vital mineral that helps your body function properly. It is necessary for producing hemoglobin, the protein in red blood cells that carries oxygen from your lungs to the organs, muscles, and tissues.
When iron stores—measured by ferritin levels—drop too low, the body cannot produce enough healthy red blood cells. This can lead to Iron Deficiency Anemia, a condition where tissues receive less oxygen and the body may feel weak or fatigued.
