Phytoestrogens are plant-derived compounds structurally similar to human estrogens. Their use in supporting and treating vaginal dryness, especially in peri- and postmenopausal women, has a basis in scientific investigation. Vaginal dryness is often linked to reduced estrogen levels after menopause. Because phytoestrogens can bind to estrogen receptors, they have been studied as a potential alternative to hormone replacement therapy (HRT) for alleviating menopausal symptoms, including vaginal dryness.

Several randomized controlled trials and observational studies have explored the effects of phytoestrogen-rich supplements (such as those derived from soy isoflavones, red clover, and flaxseed) on vaginal health. Some studies report mild but statistically significant improvements in vaginal dryness and atrophy symptoms compared to placebo, while others find limited or no effect. A 2016 systematic review in Menopause suggested that isoflavones may have beneficial effects on vaginal symptoms, but the evidence was considered moderate and not universally conclusive. Professional guidelines, such as those from the North American Menopause Society, acknowledge the potential of phytoestrogens but generally rate the evidence as insufficient for strong recommendations.

In summary, there is scientific interest and moderate-quality evidence supporting the use of phytoestrogens for vaginal dryness, but results are mixed and effects are generally modest. Phytoestrogens are not considered as effective as local estrogen therapy, but may be a reasonable option for women seeking alternatives to conventional HRT.
