Hi
@cspc,
First of all, thanks for rating my above post as "genius". It's been a long time since anybody has referred to me as genius--in fact, NEVER. lol
Regarding dosage, since I'm sensitive to most things, including supplements, I started out slowly at 1 mg. That's more than the 600 mcg MDR, but from all the literature I'd read (which was a LOT), that 600 mcg is ridiculously low. UNLESS, you're one of the very few people who apparently can actually be allergic to it--or at the least, extremely sensitive. But I did fine at 1 mg. I then increased it by a mg a day until I got up to 12 mg, which is what a number of leading iodine researchers have been recommending. Also, I've been prescribed with chelated iron for low ferritin 2 weeks ago. From what I've read chelated iron is ototoxic too.
At 12 mg/day, most people can get their iodine levels back to optimum within 6-12 months (estimates are that as much as 90% of the population is deficient in iodine). -- Also, many people who are battling cancer often times take as much as 50-100 mg/day, until the cancer starts to recede. Some women with ovarian cancer (over 90% mortality rate) have taken as much as 200-300 mg/day. So 12 mg/day feels quite conservative to me.
One thing to be aware of is that a group of toxic materials called halides (flourines, chlorines, bromines, etc,) that are ubiquitous in our environment have settled into most people's bodies at the iodine cell receptor sites. When these halides are in turn displaced from those receptor sites by adequate iodine intake, it can lead to detoxification symptoms. So anything you can do to assist detoxification is ideal. I myself supplement with 5 grams of sodium ascorbate powder daily, regularly do epsom salts baths, drink milk thistle seed tea, and a number of other things to keep my detoxification at as high a level as I can. -- Below is link a thread I recently started here on TT.
