Increasing number of studies during the last years reveal that steroid hormone vitamin D not only regulate calcium metabolism but it influences and other biological processes like glucose metabolism, neural function, cardio-vascular and reproductive systems. More and more clinical data suggests that normal plasma vitamin D levels are required for physiological pregnancy. Vitamin D deficiency is considered as an independent risk factor for developing preeclampsia. Specific pathophysiological mechanisms are not established yet.
