Most of the body's iron is found in hemoglobin, the oxygen-carrying molecule in red blood cells. Smaller amounts of iron are found in the tissues as myoglobin and as cofactors for many enzymes. Because of its central role in the hemoglobin molecule, iron is essential for the formation of red blood cells.

The U.S. Centers for Disease Control has calculated the prevalence of iron deficiency and iron-deficient anemia in the United States from data collected from physical exams and household interviews and determined the prevalence of iron deficiency is greatest among toddlers, ages 1-2 years (7%), and menstruating adolescent and adult females, ages 12-49 (9-16%).

An iron deficiency can manifest as weakness, fatigue, shortness of breath on exertion, dizziness, tinnitus, spots before the eyes, drowsiness, irritability, infrequent menstruation, and loss of libido.

Conventional iron supplementation, including forms such as ferrous sulfate, can cause gastrointestinal side effects ? including nausea, vomiting, constipation, diarrhea, and dark-colored stools ? because these conventional forms of iron are poorly absorbed.

Thorne Research's Iron Bisglycinate provides 25 mg of elemental iron per capsule reacted with glycine for optimal absorption in the gastrointestinal tract, thus preventing the typical gastrointestinal side effects.
