I have tried Amour, Nature-Throid, and WP-Thyroid, which are natural hormones verses synthetic and felt great on it. But I had a hard time getting my prescriptions every month as it was constantly backordered and was switching between the 3 brands constantly. Then my insurance randomly dropped them. This is about 5 yeara ago so maybe supply has gotten better.

Amour helped me it too much money and levothyroxine is cheap
