• Without preservatives, magnesium stearate, or other lubricants and diluents

Most of the iron in the body 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.

Thornes Iron Bisglycinate provides 25mg of elemental iron per capsule reacted with glycine for superior absorption in the GI tract, thus preventing the typical GI side effects.
