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 standardized phytoestrogen on Taiwanese menopausal women.
OBJECTIVE To investigate the effects of st and ardized soy extract on climacteric symptoms , lipid profiles , bone markers , and serum isoflavone concentration in healthy Taiwanese postmenopausal women . MATERIAL S AND METHODS A multicenter , open-labeled , r and omized , prospect i ve , comparative study design was used . A total of 130 out patients who had undergone natural menopause were r and omly administered either 70 mg or 35 mg soy extract daily for 24 weeks . RESULTS The evidence suggests that the soy extract treatment that was administered to both groups for 1 month could help reduce climacteric scores ( reductions of 19.66 % [ p<0.01 ] and 18.85 % [ p<0.01 ] in the 35 mg and 70 mg groups compared with baseline , respectively ) , and the efficacy was more potent after 6 months of treatment . Soy isoflavone significantly reduced the total cholesterol ( reductions of 4.50 % [ p<0.01 ] and 3.06 % [ p<0.05 ] in the 35 mg and 70 mg groups , respectively ) and low density lipoprotein cholesterol levels ( reductions of 4.67 % [ p<0.05 ] and 5.09 % [ p<0.05 ] in the 35 mg and 70 mg groups , respectively ) in patients with total cholesterol > 200 mg/dL after 6 months of treatment . In patients with high bone turnover ( urinary deoxypyridinoline/creatinine > 7.4 nM/mM ) , soy extract treatment reduced the deoxypyridinoline/creatinine level by 10.53 % ( p<0.05 ) and 11.58 % ( p<0.05 ) in the 35 mg and 70 mg groups , respectively . Serum levels of isoflavone increased in both groups after 6 months of treatment . CONCLUSION Soy extract is highly efficacious at relieving menopausal symptoms and demonstrates a positive effect on the cardiovascular system and skeleton
