Every living cell, whether plant or animal, contains iron. Iron is an integral part of many proteins and enzymes that maintain good health.
Iron is an essential element for red blood cells production. About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. A deficiency in iron limits oxygen delivery to cells, resulting in fatigue, poor work performance and decreased immunity.
Iron deficiency is the most common nutrient deficiency worldwide. It affects all ages, with children, women who are pregnant or menstruating, and people receiving kidney dialysis among those at highest risk for this condition.
According to the World Health Organization (WHO), Iron deficiency is estimated to contribute 50% of all cases of anemia. Maintaining the optimal balance of iron within the body is therefore essential to one's health.
