Sun Exposure may Deplete Folate Levels in Young Women

A recent study shows that women who are trying to increase their likelihood of conception by taking folic acid supplements may reduce their ability to conceive if they spend too much time in the sun.

According to researchers from Queensland University of Technology's AusSum Research Lab, they found that ultraviolet radiation exposure could significantly deplete folate levels in young women.

For the study, Professor Michael Kimlin and Dr. David Borradale of the university examined 45 young healthy women living in Brisbane, all between the ages of 18 and 47.

The findings showed that frequent sun exposure led to a 20 percent decrease in folate levels.

"This is concerning as the benefits of folic acid are well-known, with health professionals urging young women to take a folic acid supplement prior to and during pregnancy," Kimlin said, via a press release. "Folate has been found to reduce miscarriage and neural tube defects such as spina bifida in unborn babies. The NHMRC recommends pregnant women or those planning a pregnancy take 500 micrograms a day."

Researchers note that the latest findings showed how many of the participants had folate levels below the recommended levels for woman of child-bearing age.

"The women at risk were those who were outside during the most UV intense time of the day, between 10am and 3pm, with little sun protection," Kimlin added, via the release. "These were the women who had the highest levels of sun exposure and the lowest levels of folate, whilst not deficient in folate, they were on the lower side of normal."

"We are not telling women to stop taking folate supplements, but rather urging women to talk to their doctor about their folate levels and the importance of folate in their diet, especially those who are planning a pregnancy," Borradale added, via the release. "The results of this study reinforce the need for adequate folate levels prior to and during pregnancy."

The findings are published in the Journal of Photochemistry and Photobiology B:Biology.
