A recent study performed by UK researchers analyzed the success rate of assisted reproduction therapy (ART) and their vitamin D status in 2700 women. They revealed only 26% women included in the study had sufficient vitamin D, whereas 35% were deficient and 45% had insufficient concentrations. The analysis showed that the women with sufficient vitamin D levels were one third more likely to have successful ART and live births.

This current analysis supports that vitamin D plays an important role in fertilization and pregnancy. However, its role, mechanism, and optimum blood concentrations are still unknown. However, vitamin D being relatively simple and cost-effective, would you consider testing of vitamin D level and recommending supplements before starting with ART in such women?
