A Guideline Development Group (GDG) reviewed existing new evidence for two antenatal nutrition recommendations regarding Multiple Micronutrient Supplements (MMS) during pregnancy and Vitamin D supplements during pregnancy for updating of recommendations in the World Health Organization (WHO) 2016 Antenatal Care (ANC) guidelines, in accordance with WHO’s living guidelines approach. The 2020 guideline presents that evidence and updated recommendation on antenatal MMS, which supersedes the corresponding recommendation issued in the WHO 2016 ANC guideline.
