A new randomized controlled trial published in American Journal of Obstetrics and Gynecology found that high-dose vitamin D supplementation did not reduce the recurrence of bacterial vaginosis.
Bacterial vaginosis (BV) is the most common vaginal infection for women of reproductive age, affecting nearly 30% of women in the United States.
BV occurs when the natural balance of vaginal bacteria is disturbed by an overgrowth of one type of bacteria. Doctors do not know yet how BV develops, but there are known risk factors, such as unprotected sexual intercourse. However, BV is not considered a sexually transmitted infection (STI).
