phytoestrogens and Headache

In recent years, considerable attention has been paid to isoflavones and their proprieties to alleviate the climacteric symptoms. The goal of this study was to evaluate the efficacy of standardized isoflavones extract (Soyfem) in moderate and medium-severe climacteric syndrome.. 555 postmenopausal women were recruited for the study. Out of this group, 169 women completed the study (12-month observation period). The patients were classified according to the intensity of climacteric symptoms (< or = 34 points in Kupperman index). 1 or 2 tablets of Soyfem were administered twice a day.. A regular decrease of Kupperman index value and improvement of life quality were observed in the group of 169 postmenopausal women. We have noted a decrease in the intensity and number of hot flushes, diaphoresis (p < 0.05), diminished sleep disturbances (p < 0.05), decreased headache, dizziness, and arthrosis pain. The diminished intensity of tiredness, palpitation and breathlessness have been also observed (p < 0.05). 80% of all investigated women noted the regression of paresthesis, 20% indicated the decreased number of paresthesis (p < 0.05). Influence of Soyfem on the variability and moderation of depressive mood (p < 0.05) have been also positive evaluated by patients.. Administration of Soyfem in the dosage 52 to 104 mg/24 hours (2 times daily 1 or 2 tablets) is a safe and effective therapy in the postmenopausal women with moderate and medium-severe climacteric syndrome evaluated according to the Kupperman index. Administration of Soyfem is connected with a good compliance and correlated with well-being in the investigated women allowing a long-term administration.

Up to 80 % of the Western female population experience premenstrual syndrome (PMS). Long-term pharmacological therapy is unacceptable to most women, and is not warranted for moderate symptoms. Nutritional therapies are popular, but lack a clear evidence base. Anecdotal evidence suggests beneficial effects of soy isoflavones because of their influence on endogenous oestrogen and actions on specific tissues. The effect of isolated soya protein (ISP) containing 68 mg/d (aglycone equivalents) soy isoflavones (IF) on premenstrual symptom severity was studied in a seven-menstrual cycle, double-blind, placebo-controlled, crossover intervention study in twenty-three women with prospectively confirmed PMS aged 18-35 years and BMI 19-30 kg/m(2). ISP containing IF or milk protein placebo was consumed for two complete menstrual cycles. ISP containing IF (genistein, daidzein, equol) were measured in 24 h urine samples. After two cycles of ISP containing IF intervention, total symptoms (F(2,36) 8.20, P=0.000) and physical symptoms (F(2,36) 8.18, P=0.000) were significantly reduced compared with baseline after both active and placebo treatments, although differences between active and placebo treatment were non-significant. Specific premenstrual symptoms, headache (F(2,32) 4.10, P=0.026) and breast tenderness (F(2,32) 4.59, P=0.018), were reduced from baseline after soy IF, but not milk protein placebo. Cramps (F(2,32) 4.15, P=0.025) and swelling (F(2,32) 4.64, P=0.017) were significantly lower after active treatment compared with placebo. Concentrations of genistein and daidzein were increased following soy IF consumption, but equol production did not enhance symptom reduction. The present study showed that ISP containing IF may have potential to reduce specific premenstrual symptoms via non-classical actions.
