Multiple Micronutrient Supplementation (MMS) Basics

What is MMS?

Multiple Micronutrient Supplements (MMS)

MMS is a daily nutritional supplement of vitamins and minerals for pregnant women.

It consists of 15 micronutrients.

It is also called:

  • prenatal vitamins

Multiple micronutrients in MMS help the mother and baby

The earlier a woman begins taking MMS and consistently takes 1 each day, the greater the impact the multiple micronutrients may have on her health and the health of her child.

MMS helps:

  • Reduce anemia, night blindness, and other symptoms caused by vitamin and mineral deficiencies
  • Improve birth outcomes including proper weight
  • Decrease preterm births
  • Reduce stillbirths
  • Reduce risk of infants dying before 6 months of age
  • Support a healthy immune system
  • Promote physical and mental development in infants
  • Builds a strong foundation for your baby to grow and develop into a healthy child

  1. Vitamin B3 and E: Healthy cells
  2. Vitamin B1: Healthy nerves
  3. Vitamin D: Healthy bones

MMS are easy to take

  • Take 1 (one) MMS pill/tablet a day, every day throughout pregnancy
  • A woman should begin taking MMS as soon as she knows she is pregnant
  • If there are MMS remaining in the bottle after birth, take the remaining tablets while breastfeeding
  • Do not take together with IFA
  • If a day is missed, continue taking 1 tablet a day after the missed day.  Do not take 2 pills/tablets the next day
  • Keep MMS out of reach of children
Side Effects

Minor Side Effects 

When taken as directed, some women experience:

  • Upset stomach
  • Constipation
  • Headaches
  • Unusual or unpleasant taste in their mouth after taking MMS

Managing Side Effects 

Side effects are usually temporary and will go away as the body adjusts to the MMS.

Taking MMS at night and/or with food and water may help reduce side effects.

If side effects persist, advise the pregnant woman to speak to her antenatal care specialist.

Has additional benefits for the pregnant woman
Has benefits for the baby
  • Do not offer MMS to a woman who is already taking IFA supplements.
  • Do not take both MMS and IFA.  This results in too much iron in the pregnant woman’s body.  Choose 1 or the other and take that throughout pregnancy.
  • Do not alternate MMS and IFA pills every day.  Take either 1 or the other throughout pregnancy.
Increasing Adherence

Ideas to encourage pregnant women to continue taking MMS throughout their pregnancy:

  • Discuss where to keep the MMS in her home.  Remind her to keep the MMS pills in a safe, cool, dry place as that will prevent the pills from turning color.
  • Ask the woman if she has any concerns about MMS or if there is a reason she might not take it. If so, help answer any questions and address her concerns.

☑ Take MMS at the same time each day

☑ Set an alarm or reminder to take MMS daily

☑ Keep the bottle in a location where it is seen every day (out of reach of children)

☑ Ask family or friends to help give reminders
