An important 2009 study shows that Vitamin D plays a very important role in preventing pregnancy complications. This is in addition to other studies that demonstrate the importance of getting enough of the sunshine vitamin while pregnant.
This particular study, carried out by Dr. Bruce Hollis and Dr. Carol Wagner of the Medical University of South Carolina, gave 600 women of various races, 4000 IU of Vitamin D per day, and followed them throughout their pregnancies and beyond (for 2.5 years). The control group received 400 IU per day, the official recommended amount of Vitamin D.
In the group receiving 4000 IU of Vitamin D, there were half the premature births as the c0ntrol group. Fewer babies who were “small for date” were born in the 4000 IU group. The treatment group also had 25% fewer infections. The “core morbidities” of pregnancy were reduced by 30%; these include diabetes, preeclampsia, and high blood pressure. Additionally, babies getting extra Vitamin D also suffered from fewer colds and less eczema after birth. In other words, consuming 4000 IU of Vitamin D per day, 10 times the RDA, was associated with better health of mother and child. And, during the course of the study, there were no adverse effects reported from taking that much Vitamin D.
Sadly, many Americans have now lost the ability to make Vitamin D because we are in the autumn, and the sun’s rays are not strong enough to cause our skins to produce Vitamin D. This means many mothers (and babies) will be at risk of preventable pregnancy complications, unless they take Vitamin D supplements.
