Brief summary

This is an individually randomized controlled trial to assess the effect of multiple micronutrient supplements (MMS) containing 60 and 45 mg iron as compared to MMS containing 30 mg of iron (standard UNIMMAP formulation) on maternal moderate or severe anemia. This study will help inform countries like Tanzania that currently use IFA containing 60 mg of iron regarding the dose of iron to use in MMS.

Interventions

MMS with 30 mg iron is the active comparator group. The standard UNIMMAP MMS formulation includes 30 mg of iron which will be taken orally once daily from the time of randomization until delivery.

MMS with 45 mg iron is an intervention group. MMS with 45 mg of iron plus standard UNIMMAP formulation for other 14 micronutrients will be taken orally once daily from the time of randomization until delivery.

MMS with 60 mg iron is an intervention group. MMS with 60 mg of iron plus standard UNIMMAP formulation for other 14 micronutrients will be taken orally once daily from the time of randomization until delivery.
