Mechanism of action

Red clover is rich in isoflavones (genistein, daidzein, formononetin, biochanin A) that have structural similarity to estradiol and can bind estrogen receptors with varying affinity. These phytoestrogens may exert selective estrogen receptor modulator (SERM)-like effects, potentially influencing bone metabolism, vasomotor symptoms, and cardiovascular function. The mechanism remains incompletely characterized and effects are generally modest.
