IVF and vitamin DAn analysis of recent studies found that women undergoing in vitro fertilization appear to have a higher rate of successful births if they're getting adequate vitamin D.

Vitamin D deficiency is common among women who have trouble conceiving, but it's also common among the general population. Individual studies linking vitamin D levels to conception success have shown mixed results.

But when researchers analyzed data from 11 of those studies, they found women with sufficient vitamin D did have a better chance of successful embryo implantation and experienced fewer complications during their pregnancies. The vitamin levels did not seem to affect the woman's chances of a miscarriage.

The study's authors said testing vitamin D levels is relatively inexpensive and women seeking fertility treatments could use those test to optimize their levels and improve their chances.

The journal Human Reproduction published the meta-analysis in its January issue, studying cases involving 2,700 women in North America, Europe and western Asia.

Dr. Leigh Wagner, formerly of Integrative Medicine at The University of Kansas Health System, says there aren't many foods with naturally high levels of vitamin D, so most people with deficiencies do opt to take supplements. Some foods that do have higher levels of vitamin D include salmon, fish oil, Asian mushrooms and vitamin-D fortified milk.

Wagner says sunshine is another way to get vitamin D, and anyone needing more of it should spend more time outside during the daylight hours.
