[quote]So lets say one needed to take in 0.75 grams if iodine for IR. How many days would it take to intake 0.75 grams with the RDA of 150mcg. Simple, 0.75 grams /0.00015 grams per day = 5000 days. But over 5000 days you would loose most of that and for all intents and purposes, the RDA will never fix ID.
For IR you can take up to 50 mg iodine per day and get .75 grams in two weeks. I did that and started to feel better in 2-3 days. Some health food stores will have high potency iodine supplements. Many get a product called Iodoral from internet stores which is 12.5 mg iodine. Iodine was a common disinfectant in every home years ago. Rarely seen now. It was applied to cuts etc. But that stung and fell out of favour. So in large doses such as 50mg, it starts to kill of some of the bacteria in your gut. That can cause some disturbances for some, farting and loose stools etc. After a while I had that problem and skipped the iodine for a day then went on with a lower dose. So you can do something similar as needed. [/quote]
So 50mg/day for two weeks for IR. Or, if symptoms occur from the high dosage during IR, one can prolong the IR phase by taking a smaller dosage or taking days off.
After that is just maintenance, during which a total of 12.5mg/month is fine. So half a tab every two weeks.
