Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Soy has been widely studied for its potential to alleviate hot flashes, particularly in menopausal women. The scientific interest centers around isoflavones, a class of phytoestrogens found in soybeans that can weakly mimic the action of estrogen in the body. Since declining estrogen levels are a key driver of hot flashes in menopause, it is hypothesized that soy isoflavones may help reduce the frequency or severity of these symptoms.
A number of randomized controlled trials and meta-analyses have investigated soy's effects on hot flashes. Results are mixed: some studies report a modest reduction in the frequency and intensity of hot flashes among women consuming soy or soy isoflavone supplements, while others find no significant benefit compared to placebo. Meta-analyses generally conclude that soy isoflavones may offer a small, statistically significant benefit, but the clinical relevance is debated and the effect is usually less pronounced than that seen with hormone replacement therapy.
The North American Menopause Society and other expert groups recognize soy isoflavones as a reasonable, but not universally effective, non-hormonal option for some women seeking relief from hot flashes. Overall, the evidence supports a potential benefit, but it is considered modest, and response varies among individuals. More research is needed to clarify optimal dosing and identify which women are most likely to benefit.
