Iron Deficiency: Beyond Anemia

Iron deficiency is the most common nutritional deficiency worldwide, affecting approximately two billion people. While iron deficiency anemia, the stage at which iron stores are depleted enough to impair red blood cell production, is the most recognized manifestation, iron deficiency affects health at earlier stages before anemia develops. Understanding these broader effects and the factors that influence iron status supports better prevention and management. Iron plays essential roles throughout the body beyond its role in hemoglobin. It is required for energy metabolism in all cells, immune function, neurotransmitter synthesis including dopamine and serotonin, thyroid hormone metabolism, and DNA synthesis. Iron deficiency without anemia, sometimes called non-anemic iron deficiency, can cause fatigue, reduced exercise capacity, impaired cognitive function, hair loss, restless legs syndrome, and reduced immune competence even when hemoglobin remains normal. Groups at highest risk for iron deficiency include women of reproductive age with heavy menstrual periods, pregnant women with dramatically increased iron requirements, infants particularly those born premature or with low birth weight, toddlers and adolescents during periods of rapid growth, frequent blood donors, vegetarians and vegans who consume only non-heme iron of lower bioavailability, and individuals with conditions causing impaired iron absorption such as celiac disease or those who have undergone gastric bypass surgery.

Dietary iron comes in two forms. Heme iron found in animal products including red meat, poultry, and fish is absorbed efficiently. Non-heme iron found in plant foods including beans, lentils, tofu, fortified cereals, nuts, and dark leafy greens is less efficiently absorbed. Consuming non-heme iron foods with vitamin C significantly enhances absorption. Coffee, tea, calcium-rich foods, and foods high in phytates reduce non-heme iron absorption. Iron status is assessed through blood tests including serum ferritin, which reflects iron stores, serum iron, total iron-binding capacity, and transferrin saturation. Ferritin is the most useful single test for evaluating iron stores.
