Evaluation of Vitamin D Requirements During Pregnancy
In Brief
A Phase 3 clinical trial evaluating cholecalciferol (vitamin D3) and cholecalciferol for Vitamin D Deficiency. Completed, enrolled 501 participants across 1 site.
Detailed Summary
The purpose of this study is to determine the effectiveness of vitamin D supplementation during pregnancy starting at the beginning of the second trimester. Mothers will be randomized to one of three vitamin D dosing groups: 400, 2,000 or 4,000 international units per day. It is hypothesized that the highest dosing regimen will result in a better vitamin D status of women regardless of their ethnicity or race.
