A new research paper has been published by Hoermann, Midgley et al. It is published in the Clinical Endocrinology Journal.
There are some positive things happening in the endocrinology world, but I am expecting this to be very slow.
Some of the take-away conclusions are that:
“In some people, no amount of T4 will regain normal FT3 levels”
and that
“…gurus now admit that some people cannot handle T4 and regain health”!
Here’s the paper information:
