Across 4 studies, all reported beneficial effects of iron supplementation or fortification on reducing iron deficiency, with effect sizes ranging from small to large (2 large, 1 moderate, 1 small). The strongest evidence comes from meta-analyses in pregnant women and general populations, showing large reductions in iron deficiency risk (e.g., RR 0.24 for maternal deficiency at term; RR 0.36 for iron deficiency with food fortification). Doses varied widely (0.2–112.8 mg/day or per serving), and the most-studied population was pregnant women.
