NCT00076050

Brief Summary

The purpose of this study is to determine if soy-derived phytoestrogens (naturally occurring compounds similar to estrogen) can prevent bone loss and other menopausal symptoms in women who have recently gone through menopause. Study hypothesis: Tablets of high-dose, purified soy phytoestrogens spare the normally occurring spinal bone loss and improve biological and other emotional changes of menopause.
