Do packaged foods like soy sauce use iodized salt? Would it be best to assume they do?
Well, iodized salt costs more, so I would assume not... also, from the Salt institute:
I don't think there is a reliable source on it, but I'd agree with 1man Island, follow the money. Iodine supplements are pretty inexpensive, or just buy and use iodized salt.
A lot of food manufacturers here in Europe will go so far as to specify that they use non-iodized salt in their products, so I can't assume it's any different than in the States.
The iodine/vitamin D mix from life extension is a good option, kills two birds with one stone IMO.
I take the same product, but the one with vitamin K.
