To be frank I've lost count of how many times I've read stories of people who seemingly have no clue why they're taking thyroid or how to take thyroid intelligently. Many haven't read Broda Barnes, or Ray's articles, and start off on 2 grains right off the bat, and then they switch to a different product the week after, then wonder why it doesn't work on them...This explains the vast majority of problems encountered on this forum.
Are you saying you take thyroid because you don't think you can make it naturally? :)
