Vitamin D in Pregnancy Results in Stronger Bones for Kids

A study from the MAVIDOS trial found that gestational supplementation of 1000 IU/day of vitamin D3 from early pregnancy until delivery improves bone mineral content, bone mineral density (BMD), and bone mineral apparent density in children at age 6-7 years. The trial involved 1134 pregnant women, with 454 children followed up at age 6-7. Previous results showed increased BMD at age 4, but no differences at birth. This post hoc analysis reaffirms the long-term benefits of prenatal vitamin D supplementation on children’s bone health.

Research shows that taking 1000 IU of vitamin D3 during pregnancy strengthens children’s bones at ages 4 and 6-7. How might this finding influence prenatal care recommendations in the future?

That’s super interesting! I’ve always heard about how important vitamin D is during pregnancy, but I didn’t realize it could have such a long-term impact on a child’s bone health. Do you know if there are any specific factors (like diet or environment) that might influence how well the vitamin D supplementation works during pregnancy? Would it be recommended for all pregnant women, or only those with certain deficiencies?
