I am not converting t4 to t3 very well. My endo doc said it's toxins and that I have autoimmune thyroiditis. I have four crowns and under 3 of them I have large amalgam fillings that I've had for the last 40 years. There is no way I'm having these out. $$$$$ I'd end up with dentures and that would only be if my doctor said it was that or death. I heard that you can swish organic coconut oil around your mouth 1/day and get rid of the heavy metals and drink distilled water which is supposed to tie up heavy inorganic metals and get them out of your body. I also heard poor t4 to t3 conversion can just be old age. Can somebody address all of this information. Please.
