Hi, I'm waiting on my delivery of Thyroid-S. I was reading up on how best to make the switch, and how to be successful with NDT. Someone here suggested on another thread that you can just switch over, I assume that means one day I take the last levo and then the next start NDT? Then I've read elsewhere I'll need to stay off levo for at least a week, supplement with ferritin and selenium. But then! I've also read that taking iron supplements can bind with NDT and make it unusable??
Also, when reading here about taking Thyroid-S, people say begin with 1 grain, move up in quarters, but pretty sure Thyroid-S is tablets? Should I buy a pill cutter and cut them in 4?
