Just seen this FREE online 'Heavy Metal' summit (Jan 2018) - no it's not the music genre ;-D but about environmental toxins we're all exposed to.
Dr Durrant-Peatfield talks about environmental toxins affecting thyroid function, in his book 'Your Thyroid & How To Keep It Healthy'.
I have a long history of thyroid problems and have discovered that I have 'lead, arsenic and mercury' toxicity. I wonder if this the root cause of my thyroid hormone problems? Could it be the cause of yours too?
Here's the link to register on the summit:
NB I am not affiliated to this summit, I just saw it and thought it maybe of interest, so sharing the link with you
