Soy Isoflavones Treatment Menopausal Symptoms.

Soy Bean Extract INCI Name Glycine Soja Extract Soy Isoflavones Genistein Daidzein CAS 84776-91-0 Genistein CAS 446-72-0 Daidzein CAS486-66-8 photo picture image Hot flushes (flashes) are the primary reason that women seek medical attention for menopausal symptoms. Concern over potential adverse effects of hormone replacement therapy has led to increased interest in the use of phytoestrogen supplements by women experiencing menopausal symptoms. The effects of increasing soy isoflavone intake on the frequency of hot flushes have been examined in a number of randomized controlled trials. Out of 8 randomized controlled trials of soy foods, only one found a significant reduction in the frequency of hot flushes, while 3 out of 5 controlled trials of soy isoflavone extracts reported a significant reduction in hot flush frequency.
 In general, any reductions observed were modest (10-20%) compared to placebo. Breast cancer survivors in particular may experience more frequent and severe hot flushes related to therapies aimed at preventing breast cancer recurrence. However, none of the randomized controlled trials in breast cancer survivors found that soy isoflavone supplementation was significantly more effective than a placebo in decreasing the frequency or severity of hot flushes. Overall, there is little evidence that increasing soy isoflavone intake from food or supplements substantially improves menopausal hot flushes.
