The World Health Organization’s guide, “Daily Iron supplementation in postpartum women (2016)” argues women should take iron supplements after giving birth. It does by citing facts of iron deficiency in women, developing the guidelines based on the WHO handbook for guideline development, and used a group of experts to do so. The purpose of the guide is to explain the importance of taking iron supplements after giving birth in order to improve maternal and infant health outcomes, help member states make informed decisions on the appropriate nutrition actions needed to achieve the Sustainable Development Goals developed by WHO, and help member states achieve the global targets of the comprehensive implementation plan on maternal, infant, and young child nutrition. It was created for a wide audience, including policy-makers and their advisers as well as program staff at organizations involved in the design of programs for anaemia prevention & control.
