Phytoestrogens are weaker so they might compete for receptors with estrogen from your hrt

True!  Don't combine strategies....  Could be deadly even!

I'm not. There's foods I eat and supplements I take for my chronic illness that have phytoestrogens in them. I was wondering how much of this is theoretical in terms of blocking. I can't make any sense out of studies on this subject.

Are you under Doctor's care for HRT or DIY?  If you are seeing a Doctor, it's best to consult with him/her.   I would think normal foods would not have enough estrogenic properties to be much of a problem...  But PM , soy and the like could have a negative impact.

How much soy would have an impact? I mean soy is really hard to avoid, it's in pretty much all processed foods, and yeah it's healthier to not eat processed foods, they're cheap and easier to make than making food from scratch with fresh ingredients.
