Possible Interactions with: SoySoy; Soy isoflavones; Soy protein; Soy protein extract; Soybean
The phytoestrogen components of soy may interfere with the drug tamoxifen (Nolvadex), used in breast cancer treatment for men and women, and the drug raloxifene (Evista), used to prevent and treat osteoporosis. The minerals zinc and iron may also interfere with the absorption of soy and could theoretically lower soy levels in the body. Further research is needed.
