Forgot to mention... please read previous post.

I've taken levothyroxin all my life, switched to synthroid for just one month of the 112mg . Decided to go back to levothyroxin with my new dosage 125mg was told by a friend to stick with brand I've always used. Does it really matter?

I'd say you are under medicated.

Also ferretin and vitamin D are very low I'd supplement.

Have you thought of trying NDT?

Levothyroxine is just T4 replacement whereas NDT gives you all the T's

I feel so much better on it.

Send your results to Clutter or one of the other admin to decipher.

I believe synthroid is just another brand of levothyroxine. It shouldn't make a difference unless you are sensitive to some of the fillers used in the tablets (which most people aren't). So unless you can feel a difference it doesn't matter.

About 10 yrs ago when new to thyroid meds, I took Synthroid at first. Then started to have bad palpitations; eventually figured out it was due to the Synthroid. Switched to Levothyroxine and was good to go; no more palpitations. Have been with that drug, ever since.
