Thanks for the reply. What dose are you maintaining at? I am probably going to start thyroid meds again. I absolutely don't want to be hypo and pregnant. Maybe the combo of meds and Iodine is what I need. I think that the Hashimoto's has probably damaged some of my gland beyond repair. I've been hypo most my life and didn't know it until a few years ago (lots of time for lots of damage). Where do you get your kelp from? I would like to add some to diet and found one source Maine coast sea vegetables that at least states that they test their seaweed for contaminates and are certified organic.
