I just did a quick search to find out how much stronger estrogen is than phytoestrogens and got 3 different answers straight away. A couple of sources claim that phytoestrogens may be anywhere from 1/100th to 1/1000th the strength of estradiol, but other sources said 1/50th the strength of estradiol and 1/200th the strength.
