Red Clover Extract contains specific isoflavones, including genistein, daidzein, biochanin and formononetin. Isoflavones are phytoestrogens, plant compounds with a weak estrogenic effect, which can help balance the body's estrogen levels. When estrogen levels are high, they may work by competing for and binding to the body's estrogen receptors, causing excess circulating estrogen to be sent to the liver for elimination. When the body is low in estrogen, the situation during menopause, phytoestrogens may substitute for the lack of human estrogen, mitigating the effects of its absence. Research shows that red clover may help in maintaining a healthy cardiovascular system during menopause.
