First, isoflavones have been studied extensively and are a great alternative for women who can't or do not wish to take HRT. In addition to menopausal benefits, studies on large Asian populations have shown that isoflavones may play a role in cancer prevention, cardiovascular health, and bone and mineral metabolism. Isoflavones have been shown to have many estrogen-like effects in the body, but without estrogen's risks! There appears to be no negative effects on breast or uterine tissue and no apparent risk of blood clots or migraines.
Black cohosh is another popular natural treatment for many menopausal symptoms. Numerous studies on the standardized extract containing 27-deoxyacteine, have repeatedly shown its clinical benefit without any safety issues. The research on the menopausal benefits of black cohosh is even stronger than for isoflavones! Again, this is a great alternative for women who can't or do not wish to take HRT.
