Study Summary
The goal of this project is to utilize stable isotopically labeled vitamin D3 and state of the art mass spectrometric methodology to assess vitamin D dynamics during pregnancy in relation to relation to obesity and vitamin D binding protein genotype. At the conclusion of this study, the investigators will have obtained novel information on the absorption and utilization of vitamin D in women and the degree to which vitamin D utilization during pregnancy is impacted by genetic ancestry, vitamin D binding protein concentration and genotype and by excess adiposity. The long-term goal is to better understand the unique metabolism of vitamin D during pregnancy.
Primary Outcome
A baseline blood sample (20 mL) will be obtained for analysis of the baseline concentrations of indicators of vitamin D status. Each woman will be asked to ingest two pieces of toast onto which a dose of 35 μg of \[6,19,19-d3\]-vitamin D3 has been added. Women will return to the at 4 hour, 8 hour, Day 2, 10, 25, and 40 (± 2 days) for an additional blood sample (15 mL each) to assess the disappearance of the tri-deuterated D3, conversion into 25(OH)D3, and serum half-life of 25(OH)D3.
