After menopause Soy isoflavones and other phytoestrogens can provide suf icient estrogenic activity as to reduce
hot flashes and other menopausal symptoms, as well as help to support bone density. Soy intervention trials have
shown a reduction in hot flashes by up to 40 percent in various studies.1,6,7,8
Soy constituents (especially diadzein and genistein) have been linked to favourable ef ects on bone density in
postmenopausal women and in animal experimental studies, often using ovariectomized rats.
Dailais et al found that early postmenopausal women had a 5 percent increase in bone mineral content compared
with baseline values after only 3 months of consuming Soy flour. Ipriflavone, a semisynthetic compound similar to
the Soy isoflavone, diadzein, has been shown to increase bone density in postmenopausal women, at a dosage of
200 mg, three times daily.1 It is approved in Japan, Hungary and Italy as a drug for the treatment and prevention of
osteoporosis.1,9
