Although the relevance of magnesium in obstetrics has been known for a long time and its effect in many diseases is well documented, oral magnesium supplementation during pregnancy is a subject of discussion. The evaluation of the variety of studies regarding magnesium supplementation in pregnancy clearly shows positive effects of oral substitution, in contrast to the Cochrane analysis. In addition to the needs of the growth of the fetus and the maternal tissue, elevated renal magnesium excretion is a reason for an increased magnesium requirement during pregnancy. This enhanced renal loss leads to a decreased serum magnesium concentration, which can also be recognized in the myometrium.
