By the fourth week of the clinical trial, subjects that were given soy supplement showed a significant reduction in the mean number of hot flushes per 24 hours. By week 12, there was a 15% (p less than 0.01) decrease in the number of hot flushes in soy group subjects compared to the control.

This study confirms that genistein which has weak estrogenic property is able to counteract the natural loss of estrogen in post-menopausal women.Genistein is now commercially available as health food to combat such symptoms and bone loss.A note of caution however; genistein at high concentration in the body can work the reverse; it exhibits anti-estrogenic activity.This activity may be linked to genistein anti-tumour effect on breast cancer
