What it tests, as registered
Sumadhur; Multiple micronutrient supplement MMS
Registered summary
Preconception micronutrient status (including anemia) is a critical determinant of maternal, newborn, and child health that remains undervalued in Nepal. However, providing micronutrient supplements (MMS) alone is not enough. In the Nepali context, the gap between marriage and the first birth is short and newly married women have the lowest household status. The full summary is on the listing.

What it tests, as registered
Multiple micronutrient supplement (MMS) for pregnancy
Registered summary
Malnutrition among pregnant women in low- and middle-income countries (LMICs) can cause micronutrient deficiencies that result in adverse maternal and neonatal health outcomes. The World Health Organization has recently recommended antenatal multiple micronutrient supplementation (MMS) that includes iron and folic acid (IFA) to improve maternal and neonatal health outcomes. MMS likely provides additional antenatal benefits over IFA supplementation alone. The full summary is on the listing.
