Magnesium and calcium work in combination: Magnesium relaxes muscles, while calcium stimulates muscles to contract. Research suggests that getting adequate magnesium during pregnancy can help prevent the uterus from contracting prematurely. Magnesium also helps build strong teeth and bones in your baby.

Magnesium Deficiency during pregnancy can lead to preeclampsia, poor growth, and infant mortality.

During pregnancy: 350 mg/day is the recommended dietary intake (RDI) for pregnant women aged 19-30 years. Pregnant women aged 14-18 years is 400 mg/day and 360 mg/day for women aged 31-50 years.
