You can get natural thyroid hormone though somewhere, which is safer and err - natural. The much better option. Just a word of warning.
I actually agree here, but not because natural is always better. In this case it contains all the hormones the thyroid makes rather than just one. For people with resistance to thyroid hormones caused by polyglandular syndrome it is the only choice, and for everyone it can help prevent osteoporosis.
