Iron Deficiency


Iron deficiency is the most common known form of nutritional deficiency. Iron is present in each human red blood cell and its most vital function is to carry oxygen to the tissues from the lungs through our blood. Recognizing the signs of iron deficiency is the first step to making sure your iron levels are normal. If you experience any of the symptoms of iron deficiency listed below, you may have an iron deficiency.
