Armour is made from pig hormone. Synthroid is totally synthetic hormone. Go to the manufacturers web site to see the ingredients that are active and inactive. Sounds like you read something that isn’t true. I thought you weren’t going to read the internet late at night anymore. The Aboutthyroid web site has lots of good information on what’s in the different thyroid hormone choices from different companies.
I’m not sure where you got the information about the content of Synthroid. If you go to the manufacturer’ s (Abbott) of Synthroid website to — http://rxabbott.com/pdf/synthroid.pdf —you will be able to find out from the company the ingredients.
