So after doing a bit of searching I found this article: https://www.uclahealth.org/news/article/3-ways-increase-estrogen-naturally
This seems like a bit more of a realistic plan for designing foods/drinks that help boost estrogen levels. Not a substitute for HRT by any means, but rather something that could supplement/enhance it that is also relatively safe to consume regularly.
The liver ruins it so no.
Had to look it up but there is an oral version used to treat breast cancer, there’s some differences but science has gotten close enough without even trying so it’s probably doable.
I mean it’s a general known fact around here that oral e is not the best.
