Body identical hrt is all plant derived from yams and soya, and standardised - you must also take progesterone to protect the lining of the womb from extra oestrogen. I didn't want to touch soy as it can affect thyroid levels as does oral oestrogen of any sort as it goes through the liver (eg contraception or hrt.)
I don't understand why people are so suspicious tbh.
For me it's like taking thyroxine (and a few do need t3 which nhs do give if it's identified as a need) v natural dessicated thyroid from pigs which isn't regulated.
Newson has cashed in from the medical industry's neglect of womens health for sure, but she did initially seek out nhs funding and there was none. So she was forced to go private, I'm uncomfortable with all that but it's clear the nhs have failed women when most medical degrees don't even cover menopause.
The menopause industry is enormous and mostly expensive supplements.
Women are clearly struggling or there's be no need for either.
I devoured all the supplement advice form lara briden (taurine does help) but it eventually didn't work enough.
