A new study has found that daily supplementation with Vitamin D is more effective than sun exposure on a daily basis for raising pregnant women’s Vitamin D levels.
87 pregnant women with Vitamin D levels below 30 ng/ml participated in this study. The study lasted 10 weeks. Half of the participants received 4,000 IU of Vitamin D3 daily. The rest of the participants were told to expose at least 30% of their skin to the sun for 30 minutes, between the 10 AM and 4 PM hours, using no sunscreen. All of the participants were 14-18 weeks into their pregnancies, had 2 or 3 different skin types and worked indoors.
Researchers found that there were no significant differences in the participant’s baseline Vitamin D levels. Vitamin D levels increased significantly in both groups. At the end of the 10 week trial period the group of women who had supplemented the Vitamin D had a significantly higher Vitamin D level when compared to the sun exposed group of women. Researchers concluded that Vitamin D supplementation was the preferred means of increasing Vitamin D levels in pregnant women with a Vitamin D deficiency.
