A Randomized Clinical Trial with Oral Magnesium Supplementation in Pregnancy

Joao Guilherme Bezerra Alves from the Instituto de Medicina Integral Professor Fernando Figueira in Brazil will perform a randomized controlled trial to assess whether a daily oral supplement of magnesium citrate can prevent placental vascular disease, which can lead to preterm birth. Placental vascular disease restricts the flow of nutrients to the fetus and can cause growth restriction and maternal hypertensive disorders. Magnesium is known to promote placental vascular flow, and magnesium citrate is safe, inexpensive and easily absorbed in the body. They will perform a clinical trial in two large hospitals in Brazil in which 3,000 pregnant women will be offered a daily magnesium supplement or a placebo control starting from up to 20 weeks of gestation and continuing until birth. The effect on various outcomes including placental function, preterm labor, and mother and child health will be evaluated.
