Summary

This study tests whether taking vitamin D and prebiotics (inulin) during early pregnancy can help control blood sugar in women at high risk for gestational diabetes. 500 pregnant women will receive supplements or placebos from 6-15 weeks of pregnancy. The goal is to see if these simple additions can lower fasting glucose and HbA1c levels.
