Vitamin D levels are very important to your personal health as well as that of your baby. I have previously written about how Vitamin D reduces pre-eclampsia, or toxemia of pregnancy. Vitamin D supplementation during pregnancy and infancy prevents childhood Type 1 diabetes. And low levels of Vitamin D during pregnancy and lactation have caused preclinical rickets which have caused African American women whose skin absorption is lower, to lose custody of children on charges of suspected child abuse.
A South Carolina study of pregnancy complications and Vitamin D found:
- The 400 iu level of Vitamin D in a prenatal vitamin was inconsequential
- 4000 iu of Vitamin D reduced bad pregnancy outcomes by half compared to 400 iu.
- 4000 iu of Vitamin D is safe in pregnancy
- Virtually all African American women in sunny SC had serious deficiencies of Vitamin D
- 30% of all pregnant women in the study were severely deficient
