Red Clover Extract
Isoflavone-rich plant with weak estrogenic activity that reduces hot flashes and supports bone density and arterial flexibility.
Red Clover (Trifolium pratense) is a flowering plant rich in isoflavones, particularly genistein, daidzein, formononetin, and biochanin A. These compounds have weak estrogenic activity, making red clover popular for managing menopausal symptoms like hot flashes. Research also suggests potential benefits for bone health and cardiovascular function through its effects on lipid profiles and arterial flexibility.
