Is it true that iron supplementation raises hemoglobin levels in people with iron deficiency anemia?
Yes. A 2024 systematic review and meta-analysis of randomized trials reports that both daily and non-daily oral iron supplementation effectively increase hemoglobin concentrations in patients with iron deficiency anemia. Several smaller studies and clinical references also describe hemoglobin improvement with iron supplementation, though most cover narrower populations or add other treatments.
