Daily Iron Supplementation in Adult Women and Adolescent Girls: Guideline

The World Health Organization (WHO) released global guidance documenting the recommended daily iron supplementation in menstruating adult women and adolescent girls as an intervention for preventing anemia and iron deficiency. The new guideline recommends a daily supplement of 30-60 mg of elemental iron for three consecutive months in a year, for all menstruating women and adolescent girls where the prevalence of anemia is 40 percent or higher. The guideline summarizes those recommendations and supporting evidence, as well as other considerations and research priorities. It is intended for a wide audience, including policymakers, technical staff at government institutions, and program implementers.
