Preventing Health Disparities During Pregnancy Through Vitamin D Supplementation
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.

Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
|Official Title:||Preventing Health Disparities During Pregnancy Through Vitamin D Supplementation|
- Maternal and neonatal health status as a function of maternal and infant vitamin D status [ Time Frame: These visits will include the initial recruitment of mother at 10-14 weeks of pregnancy, monthly study visits, delivery study visit. Nine months total. ]Because the primary endpoint of the study is change in 25(OH)D from baseline to delivery, the primary analysis will be restricted to participants who have remained in the study until delivery and provided a blood sample within 6 weeks prior to delivery, at delivery, or at the post-delivery visit (completers-only analysis).

|Estimated Primary Completion Date:||April 2017 (Final data collection date for primary outcome measure)|
Active Comparator: Vitamin D 4000 IU
Subjects randomized into this arm will receive supplementation with 4000 IU/day vitamin D3 in gummy vitamin form, plus the standard prenatal vitamin (containing 400 IU vitamin D3.
Drug: 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.
Placebo Comparator: placebo gummy vitamin
Supplementation with placebo gummy vitamin form, plus the standard prenatal vitamin (containing 400 IU vitamin D3)
Drug: Placebo gummy vitamin
Subjects randomized to receive placebo, also in gummy form but manufactured without Vitamin D3, will consume 4 gummies/day beginning at 10-14 weeks of pregnancy. All subjects will take a prenatal vitamin (either chewable or pill form) also beginning at 10-14 weeks of pregnancy.
