underactive thyroid
"I used Synthroid (25, 50 or 75 for over more than 10 years, but had to use the original, not the generic because generic does not work in some people.  I've not been operated, but for over 2 years I've been using NatureThroid (32.5) instead which was recommended by my ND and have to say that all my side effects that Synthroid caused, had gone.  I almost lost all my hair and had terrible heart beats, headaches, joint pains, etc.  I do not have hashimoto, and really don't know if it works for people with this condition, but I tried NatureThroid and I am very happy with the results."
