Technical Brief: Multiple Micronutrient Supplementation During Preconception in Low- and Middle-Income Countries (Spanish)

Guidance on micronutrient supplementation before conception varies globally, ranging from folic acid alone to IFA or MMS, reflecting differences in evidence strength, nutritional risk, and programmatic considerations. Countries are increasingly asking whether starting MMS before conception provides additional benefits beyond initiating supplementation during pregnancy, particularly in settings with a high burden of micronutrient deficiencies. This technical brief translated to Spanish reviews the current evidence on preconception MMS in low- and middle-income countries.
