Plant estrogens (phytoestrogens) are approximately how much weaker than animal estrogens?

Explanation:
Phytoestrogens work by mimicking estrogen, but they bind estrogen receptors with far less affinity than animal estrogens. In practical terms, their estrogenic effects are hundreds of times weaker, commonly described as about two to four hundred times weaker than estradiol. This explains why they can have mild estrogen-like effects without the strong potency of endogenous estrogens. The other magnitudes would either overestimate or underestimate their relative strength, whereas the typical understanding places phytoestrogens in the range of roughly 200–400 times weaker.
