World Health Organization: Pregnancy publication date 2012
Recommendations
- Vitamin D supplementation is not recommended during in pregnancy to prevent the development of pre-eclampsia and its complications (47) (strong recommendation)
- In addition, due to the limited evidence currently available to directly assess the benefits and harms of the use of vitamin D supplementation alone in pregnancy for improving maternal and infant health outcomes, the use of this intervention during pregnancy as part of routine antenatal care is also not recommended (conditional recommendation)2,3.
Note: WHO bases their vitamin D ban during pregnancy on a single small Random Controlled Trial
Note that WHO states that the RCT was of VERY LOW quality
The rest of the world is arguing about 600 ==> 8,000 IU during pregnancy
Also, WHO mistakenly says no vitamin D for infant until 6 months old, and then only 200 IU
