Soy Supplements Can Cool Hot Flashes

In continuation of my update on Soy...

Taking soy to relieve hot flashes has received mixed reviews over the years. Now, researchers who took another look at 19 published studies find that soy supplements may help, at least over time. Soy has been touted as an alternative treatment to hormone replacement therapy after HRT was linked to an increased risk of breast cancer.

“For many women with symptoms and especially with concerns about hormone replacement therapy, trying soy for six to 12 weeks to see if it relieves their symptoms could be a first line of treatment,” says Melissa Melby, PhD, a professor of medical anthropology at the University of Delaware.

Researchers conclude that, Soy isoflavone supplements, derived by extraction or chemical synthesis, are significantly more effective than placebo in reducing the frequency and severity of hot flashes. Additional studies are needed to further address the complex array of factors that may affect efficacy, such as dose, isoflavone form, baseline hot flash frequency, and treatment duration.
