Argue not with idiots, lest they drag you down to their level and beat you with experience.
Iodine-Induced hypothyroidism. [Thyroid. 2001] - PubMed - NCBI
Seems the effect only lasts a few days in most people until the Thyroid adapts to the higher levels, but in some it may trigger a cascade that could result in permanent Hypothyroidism.
Wow it got quiet around here. I am wondering if certain parties have been warned/suspended or something? Maybe the discussion will be more pleasant (if not as amusing.)
An update from me: I was titrating up and taking around 30mg of Iodine and feeling just fine. However, James' questions about the whole Bromine poisoning falsity and questioning how Iodine would displace Bromine when it really happens the other way around (which was a question I also had) have caused me to lower my dose back down to 5mg (2 drops 2% Lugols). I feel this is definitely a safe amount.
Not sure I agree with the whole Iodine poison thing at 100mg (seems too low an amount to create an issue unless you have an underlying condition), but I am happy at my 5mg for now.
It's rather impossible to say, Bosnic, because natural foods vary according to season, amount of sunlight, etc and from day to day in iodine content. Lugol's solution has been standardized to contain no more nor any less than stated. But, in general, your estimate may be right. I'd go for the 2% myself, as it's much more controllable in dosage, then eat seaweeds as and when.
