It should also be kept in mind, that there is no "one size fits all" dose of iodine. Governments try to proclaim minimum amounts necessary for the whole population. Yet, we know that goitrogen consumption (bromate, bromide, brominated oils, cabbages, broccoli, nuts) varies among individuals.
We also know that women generally need more Iodine than men, and that breast tissue is a place which needs elemental iodine, as opposed to the thyroid, which stores and utilises it in its Iodide form. Thus, different tissues require differnt forms of iodine, as demonstrated by the late Dr. Benjamin Easkin. This is why Lugol's and Iodoral are superior, because they provide both forms.
The larger the breasts, the more Iodine is needed. Especially when lactating, and pregnant, becuase the mother then needs sufficient Iodine to supply both herself and baby.
To proclaim a single recommended amount as being applicable to the whole population, in my opinion , is flawed, because we know women need more than men, and variances in diet, genetics, and metabolism all play a role in determining the individual's true needs.
Fortunately, a healthy body is smart enough to eliminate excess by urination. There is much literature to suggest that the body's actual reuqirement of iodine is 100 times that recommended in the US. It is up to the individual to decide.
You ought to spend some time going over the old postings on this board as it would be well worth your time.
