"I am not sure how many mcg there are per drop, but i can tell you that the bottle dropper that comes in the lid contains .05ml per drop. This means that i drop of 3% will give you 1.46mg of Iodine and 1 drop of 7% will give you 3.4mg of iodine".
Asset Chemist sell Aqueous Iodine Oral Solution. Is this the correct stuff? I read an old post where a poster said that it has the same BP as Lugols 5%, so I assume that would be 6.25mcg per drop?? Silly question but is the aqueous stuff ready to go or does it have to be diluted?
