hashimoto's disease
"After being on Synthroid for years, I went to a wellness clinic and was put on Nature-Throid.  I cannot believe the difference it made in my life. I finally have my life back!  The head fog is gone, my energy level is back and the depression has subsided also.  The only thing Synthroid did for me is change the numbers on my thyroid blood test, nothing else. I would NEVER take Synthroid again."
