The plantPhytoestrogen and the human hormone estrogen can both bind to the cell nucleusIf the estrogen concentration in the cell is too high, the mild phytoestrogens compete with the highly active hormone estrogen for binding sites on the cell nucleus. As a result, fewer estrogens can bind to the cell nucleus and stimulate it excessively.During menopause, however, the estrogen concentration is too low, then the phytoestrogens can dock onto the free binding sites of the cell nucleus and thus support the metabolism.
