Hey ladies, since we're going to be pregnant all through winter please go on the vitamin d council website and read about vitamin d levels and pregnancy. There are so many studies being done and I feel like most doctors are unaware of how important it is. Plus, the USA has one of the lowest normal ranges of any country. Read about it and ask to be tested. Low vitamin d is linked to preterm labor, gd, preeclampsia, autism and many mental health outcomes for baby and mom. The vitamin d level they recommend for pregnant women is 40 - 80 ng/ml.
