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.*
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.*
