Magnesium in important for a wide variety of physiological processes; prominent among them is the control of muscle contractions, cardiac function, and carbohydrate metabolism. In pregnancy, low magnesium status is associated with hypertension, pre-eclampsia, gestational diabetes, leg cramping, and preterm labour. Magnesium has been used extensively in obstetrics to reduce uterine contractility in threatened preterm labour. Although current evidence does not support a requirement for magnesium supplementation for most pregnant women, those who are overweight, have risk factors for hypertensive or metabolic disorders or malabsorption syndromes, or who are carrying multiple fetuses, should pay particular attention to their diets and should be monitored for signs of magnesium deficiency. Consuming a magnesium-rich diet throughout pregnancy is recommended.
