Iodine is a massive no no. I took it and my eyes looked like they were popping out. The whole thyroid issue is so complicated, its fine if your thyroid is the root cause but for some people they never respond to medication as their problem is due to something else. ie mine is mercury. Also diagnosing thyroid problems is a joke. in the UK, it's even worse than the USA. The TSH range here is .5-4.5 fall within that range and youre fine. I had two tests done..one was .08 and the other was 4.0, these were done within a month!! So my thyroid was clearly on a rollercoaster but doctors said it was fine. They're clueless. I begged them to do T3/T4 testing but labs simply wont do them if your TSH is within the range. I had them done privately and it showed i was not converting or producing enough T4 and T3. My pituitary wasn't working. Of course this produces massive problems with your endocrine system and the whole thing breaks down. So you get adrenal fatigue, liver problems etc. Thats why using milk thistle for a lot of people makes them worse when they're attempting to detox, they think its a liver problem but its an endocrine system problem caused by the mercury. The whole process is a huge chain reaction. Quite simply put one disease causes another. You can buy thyroid meds off the internet but if you're mercury toxic, its pretty pointless as you'll just put greater strain on your body.
