| Scientific title | |
| Study objectives | A randomised double blind, placebo controlled trial of the effects of supplementation of phytoestrogens (PO) (isoflavones - 100 mg/day) on premenstrual symptoms and cognitive performance in 50 women with at least mild premenstrual symptoms for two menstrual cycles per condition is proposed. The main objective is to determine whether PO are more beneficial than placebo supplements in relieving symptoms of PMS and to assess whether the consumption of PO affects cognitive performance in the premenstrual and follicular phases of the menstrual cycle. |
