Vitamin D Suppositories for Vaginal Dryness and Sexual Function in Postmenopausal Women


After menopause the decline in estrogen levels (produced from the ovaries) is associated with significant symptoms, one of the common symptoms being vaginal dryness and reduced sexual function. Typical treatments are focused on using hormone replacement therapies (such as bioidentical estrogen) have associated health risks. New studies are evaluating for the impact of Vitamin D vaginal suppositories on vaginal dryness and sexual function in post-menopausal Women.


Vaginal dryness is the second most common symptom associated with menopause, after hot flashes. The vaginal atrophy that occurs is due to increased fractures in the collagen elastin fibres and decreased lubrication and can lead to irritation, dryness, painful intercourse, and soreness.


Vitamin D has been observed, when taken orally or used in a vaginal suppository, to reduce vaginal dryness and improve cell proliferation of the epithelium of the vaginal canal. This is possible because the basal and parabasal cellular layer in the vaginal epithelium has Vitamin D receptors, and with a decline in estrogen levels there is a decline in these receptors. Animal studies have shown that providing Vitamin D in menopause can help to increase the number of Vitamin D receptors again and support healthy cell growth in the vaginal epithelium.


As more research is being continued in this field, future research will help us determine if this is a plausible and safe treatment option to try, perhaps prior to hormone therapies, to help reduce vaginal atrophy, support healthy lubrication, and support healthy sexual function.
