Genistein? Soy vey...

Supplements containing a soy compound called genistein may help increase women's bone mass after menopause, a study suggests. Researchers found that a combination of genistein, calcium and vitamin D helped protect postmenopausal women's bone density better than calcium and vitamin D alone. In fact, women who took the soy compound showed a modest increase in bone density over two years, compared with a small decrease among women who used only calcium and vitamin D, the researchers report in the Annals of Internal Medicine.
