Summary

The purpose of this study is to give all mothers the best chance for a healthy pregnancy through vitamin D supplementation. We will study women of diverse racial/ethnic backgrounds who will receive either the current vitamin D standard of 400 IU/day (in the prenatal vitamin) or 4000 IU/day (dose found in previous pregnancy studies to achieve vitamin D sufficiency).

This research is sponsored by the W.K. Kellogg Foundation and the Medical University of South Carolina. The purpose of this study is to examine the effectiveness and infection-fighting properties of the body in relationship to vitamin D levels. This study is being done at the Medical University of South Carolina (MUSC) clinics, and will involve approximately 450 volunteers.

Vitamin D3 4000 IU in gummy form

Subjects randomized to the Vitamin D3 4000 IU gummy vitamin arm, the investigational drug, will consume 4 gummies/day beginning at 10-14 weeks of your pregnancy. All subjects will consume a prenatal vitamin (either chewable or pill form) also beginning at 10-14 weeks of your pregnancy.
