Four trials that were not combined in meta-analyses suggested that extracts with high ( > 30 mg/d ) levels of genistein consistently reduced the frequency of hot flushes .
BACKGROUND Vasomotor symptoms , such as hot flushes and night sweats , are very common during the menopausal transition .
Hormone therapy has traditionally been used as a highly effective treatment , but concerns about increased risk of some chronic diseases have markedly increased the interest of women in alternative treatments .
Some of the most popular of these treatments are foods or supplements enriched with phytoestrogens-plant-derived chemicals that have estrogenic action .
OBJECTIVES To assess the efficacy , safety and acceptability of food products , extracts and dietary supplements containing high levels of phytoestrogens when compared with no treatment , placebo or hormone therapy for the amelioration of vasomotor menopausal symptoms ( such as hot flushes and night sweats ) in perimenopausal and postmenopausal women .
Effects of a red clover extract (MF11RCE) on endometrium and sex hormones in postmenopausal women.
OBJECTIVE To evaluate the effects of a non-prescription red clover extract ( MF11 RCE , Melbrosin International , Vienna , Austria ) on selected sex hormones and endometrium in postmenopausal women . PATIENTS AND METHODS One-hundred and nine postmenopausal women with an age > or = 40 years were r and omly assigned to one of two groups either two capsules of MF11RCE ( 80 mg isoflavone ) per day for a 90 day period , or placebo of equal design . After a 7 day washout period , medication was crossed-over for another 90 days . RESULTS Combined evaluation demonstrated that supplementation with MF11RCE ( verum ) , in contrast to placebo , significantly increased plasma testosterone levels and decreased endometrial thickness . CONCLUSION MF11RCE exerts a moderate effect on testosterone levels in postmenopausal women , while estradiol levels remained unchanged . The observed reduction of endometrial thickness provides further support for a safe role for isoflavones in terms of endometrial hyperplasia
