• New research from Penn State reveals that vitamin D deficiency in early pregnancy is associated with a fourfold increase in preterm birth rates and smaller infant size at delivery.
• A complementary study by the University of Southampton demonstrates that maternal vitamin D supplementation during pregnancy leads to stronger, denser bones in children that persist until at least age 7.
• Scientists emphasize that vitamin D monitoring should be prioritized alongside other essential nutrients during preconception and early pregnancy to promote optimal fetal development and long-term health outcomes.
