NCT ID NCT02705287
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is tracking how pregnant and non-pregnant women absorb and use vitamin D, especially in relation to obesity and genetic background. Researchers will give 160 women a tiny, safe dose of labeled vitamin D and take blood samples over 40 days. The goal is to learn how pregnancy changes vitamin D dynamics, not to test a treatment.
