According to a study conducted by NIH, women who had sufficient levels of vitamin D were more likely to become pregnant as compared to women with insufficient levels of the vitamin.
Vitamin D facilitates overall growth of the unborn baby and plays a key role in modulation of cell growth, improving immunity and healthy growth of the musculoskeletal system.
Vitamin D is one of those essential vitamins during pregnancy that must be taken in the right amount- too much or too little can lead to health problems. It has been known via studies that vitamin D toxicity affects bone development and neurological function of developing a baby.
But the insufficient amount of exposure to vitamin D is also important for maintaining pregnancy. According to the authors of the study, women who have higher levels of vitamin D before undergoing in vitro fertilization have higher pregnancy rates than those with lower levels.
“Our findings suggest that vitamin D may play a protective role in pregnancy,” said Sunni L. Mumford, study’s principal investigator.
1200 women’s blood levels of vitamin D were tested before pregnancy and in the eighth week of pregnancy. The researchers say that the vitamin D levels should be above 30 nanograms per millilitre.
The study showed that the women who had sufficient preconception vitamin D concentrations were 10% more likely to become pregnant and 15% more likely to have a live birth in comparison with women who had insufficient concentrations of the vitamin.
Further studies are needed to prove the certainty that providing vitamin d to women at risk for pregnancy loss could increase their chances of pregnancy and live birth.
The study was published in the journal The Lancet Diabetes & Endocrinology.
