You can't really get too much iodide from iodized salt, if that's what you're getting at. The only thing you can get is too much sodium.
The advantage is that we all need a little iodide in our diets, and there are few sources to get it, and table salt is used so much that it's a handy place to get it from. Iodide prevents goiter.
The other disadvantage is that it's terrible for canning and pickling. You need pure salt for that (check the label, even non-iodized salt has an agent to make it pour freely in humid climates, called prussiate of sodium, and a tiny tiny amount of sugar, .004%, about 1 tablespoon per bushel, to keep the potassium iodide stable and not turn into iodine). For canning and pickling, you need salt that contains nothing but salt. Anything else will make the final product cloudy.
"Potassium iodide
Potassium iodide is added as a nutrient, to prevent goiter, a thyroid gland problem caused by lack of iodine, and to prevent mental retardation associated with iodine deficiency. A project started by the Michigan State Medical Society in 1924 promoted the addition of iodine to table salt, and by the mid 1950's, three quarters of U.S. households used only iodized salt. Potassium iodide makes up 0.06% to 0.01% of table salt by weight. Sometimes cuprous iodide (iodide of copper) is used as the source of iodine.
Iodized salt is the best to use !
Iodized salt is not organic. It's inorganic.

why is iodized salt important to the midwest
Iodized salt comes from Iodine, a necessary micronutrient!
No margarita salt is not iodized. If it was the margarita would be fizzy.
It is an error: ionized salt (NaCl) doesn't exist. Correct is iodized salt.
the temperature of boiling water that is mixed with iodized salt will decrease.
Sea salt does not have iodine added to it. The only salt that has iodine in it says iodized, such as table salt.
Yes, non-iodized salt can conduct electricity because it contains sodium and chloride ions, which are free to move and carry electric charge. The conductivity of non-iodized salt is lower compared to iodized salt because the added iodine in iodized salt can slightly enhance its conductivity.
Iodized salt helps prevent goiter and mental retardation. The non-iodized salt helps maintain the color and texture of pickled food and it does not affect the taste of food when cooking.
Sea salt can be iodized or uniodized depending on whether iodine has been added.
