February 19 2018. A study reported on February 14, 2018 in Endokrynologia Polska resulted in improvement in female sexual desire, orgasm and satisfaction, as well as mood, after supplementation with vitamin D.

Based on researchers Robert Krysiak and colleagues’ previous finding of an association between deficient vitamin D levels and abnormal female sexual function, a trial that examined the effects of six months of oral vitamin D supplementation was conducted among 47 women with deficient or insufficient plasma vitamin D levels. Women with vitamin D deficiency, defined as plasma 25-hydroxyvitamin D levels that were lower than 2 nanograms per milliliter (ng/mL), were given 4,000 international units (IU) vitamin D per day, and participants with insufficient levels of 20-30 ng/mL were given 2,000 IU daily or no vitamin D.

Questionnaires that evaluated female sexual function and depressive symptoms were completed before and after the treatment period.

At the beginning of the study, female sexual function questionnaire scores were significantly lower (indicating increased impairment of sexual function) and depression scores were higher (indicating a greater level of depression) in women with deficient vitamin D levels compared to women with insufficient levels. Supplementation with vitamin D was associated with improved sexual desire in both deficient and insufficient women. Among participants with vitamin D deficiency, vitamin D improved total sexual function scores and scores for sexual satisfaction and orgasm, while decreasing total depression scores.

In their discussion of the findings, the authors remark that “It is possible that genital blood flow, as well as hormonal and neural regulations of sexual function are disturbed in women with hypovitaminosis D and correlate with its severity.”

“The obtained results indicate that vitamin D supplementation improves female sexual functioning and mood in women with low vitamin D status,” they conclude.
