NCT ID NCT07288801
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking vitamin D supplements can prevent preeclampsia from returning in pregnant women who had it before. About 146 women will be randomly assigned to take either vitamin D or a placebo pill until 36 weeks of pregnancy. Researchers will track blood pressure and urine protein to see if vitamin D reduces the risk of recurrence.
