How Maternal Vitamin D Status Impacts Preterm Birth Risk

First trimester vitamin D levels significantly affect baby length and preterm birth risk, with every 10 nmol/L increase in maternal vitamin D corresponding to measurable increases in fetal length
Pregnant women with severe vitamin D deficiency (below 10 ng/mL) face nearly eight times higher risk of preterm birth and more than four times greater risk of developmental delays in their children
Vitamin D triggers production of natural antimicrobial substances that help protect against infections that could lead to preterm birth
Vitamin D plays a role in placental blood vessel development and helps control inflammation during pregnancy, directly impacting fetal brain development and overall pregnancy health
Strategic sun exposure is the optimal way to boost vitamin D, but care must be taken with timing and duration, especially for those consuming seed oils, which increase UV sensitivity
