Iodoral is Lugol's with binders & fillers. Who needs binders & fillers? Iodoral is recommended because it's patented(i.e. a moneymaker). Lugol's is not patented. Not that I don't think these guys deserve the money, in this case I do:) And I guess it's more precise than "drops". And, some people don't like the taste of Lugol's, I do. I crave it! :)
