The following quote was found on pdrhealth.com, and is in reference to Soy Isoflavones. They do not list cautions and contra indications on their site for Red Clover, however like soy, the main active ingredient in Red Clover is Isoflavone, so we felt that we should provide you with the most current information. In Chinese Medicine, Red Clover is not viewed the same way as Soy. None the less, both substances do contain Isoflavone, which is considered a phyto-estrogenic acting similar to, but not the same as estrogen in the body.
PRECAUTIONS
Pregnant women and nursing mothers should avoid the use of soy isoflavone supplements pending long-term safety studies. Men with prostate cancer should discuss the advisability of the use of soy isoflavones with their physicians before deciding to use them.
Women with estrogen receptor-positive tumors should exercise caution in the use of soy isoflavones and should only use them if they are recommended and monitored by a physician.
