Estrohalt is both an estrogen blocker and an aromatase inhibitor. I looked it up and it is used for estrogen dominance (too much estrogen). If it were effective in reducing estradiol below detectable levels, wouldn't the side effects be the same as a pharmaceutical AI? On the other hand, I would like to know what a doc (integrative or not) thinks about the effectiveness of this for cancer, if it does not reduce estradiol below the detectable level. Does it still help reduce risk?
