Iron Bisglycinate
Most of the body's iron is found in hemoglobin, the oxygen-carrying molecule in red blood cells. Smaller amounts 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 formation of red blood cells.*
To determine the iron status of persons in the United States, the Centers for Disease Control calculated the prevalence of iron deficiency and iron-deficient anemia from data collected from physical exams and household interviews within a sample of the U.S. civilian, non-institutionalized population. The prevalence of iron deficiency was 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 GI side effects – including nausea, vomiting, constipation, diarrhea, and dark-colored stools – because these conventional forms are poorly absorbed.
Thorne Research's Iron Bisglycinate provides 25 mg of elemental iron per capsule reacted with glycine for superior absorption in the GI tract, thus preventing the typical GI side effects.*
