I am searching for any information about the dangers of drinking too much soy milk. Is there a risk of too much estrogen (I realize that it is more of an herb that is similar to estrogen) but have concerns with getting too much from soy milk?

Welcome to 3FC! Interesting first post.

Soy milk is neither an herb nor does it contain estrogen. It does contain estrogen-like isoflavonoid substances which act like weak forms of the estrogens naturally produced in a woman's body.

As in all things, investigation and practical moderation is prudent.
