The present invention relates to a hormone replacement therapy, and a composition useful therein, for women having reduced levels of endogenous estrogen. A mammalian estrogen and an isoflavone which is incapable of being metabolized to equol are co-administered to a woman having a reduced level of endogenous estrogen. The hormone replacement therapy is effective to inhibit or prevent diseases or conditions resulting from, or exacerbated by, a reduction in endogenous estrogen including: coronary heart disease, cardiovascular disease, osteoporosis, loss of cognitive function, urinary incontinence, weight gain, fat mass gain, and vasomotor symptoms. A composition for use in the hormone replacement therapy of the present invention contains a mammalian estrogen and at least one isoflavone, where the isoflavone is incapable of being metabolized to equol by a human, and where the composition contains less than 10% by weight of isoflavones and phytoestrogens capable of being metabolized to equol by a human.

The present invention is a composition for preventing, minimizing, or reversing the development or growth of breast cancer. The composition contains a combination of a selective estrogen receptor modulator selected from at least one of raloxifene, droloxifene, toremifene, 4&prime;-iodotamoxifen, and idoxifene and at least one isoflavone selected from genistein, daidzein, biochanin A, formononetin, and their respective naturally occurring glucosides and glucoside conjugates. The present invention also provides a method of preventing, minimizng, or reversing the development or growth of breast cancer in which a selective estrogen receptor modulator selected from at least one of raloxifene, droloxifene, toremifene, 4&prime;-iodotamoxifen, and idoxifene is co-administered with at least one isoflavone selected from genistein, daidzein, biochanin A, formononetin, and their naturally occuring glucosides and glucoside conjugates to a woman having or predisposed to having breast cancer.
