itamin D is a crucial nutrient during pregnancy, yet deficiency is very common, especially among our vegan patients. This fat-soluble vitamin is found in fortified dairy products, fish, and supplements, and can also be naturally produced in the skin with sun exposure.
Severe vitamin D deficiency can increase the risk of skeletal issues in a developing baby, but even milder deficiencies have been linked to a higher risk of preeclampsia, gestational diabetes, and preterm birth. Because of this, checking vitamin D levels has become a routine part of our prenatal lab work.
Since vitamin D is fat-soluble, it’s important to supplement appropriately—too much isn’t beneficial either. That’s why I typically recheck levels in the third trimester or postpartum to ensure proper balance.
