Give the newbie a break.
Obviously the poster is not stupid; he was smart enough to post the question.
What you want, darling new person, is an
Iodine solution in water, which is
Lugol's solution, or that same type formula made into a tablet, which is Iodoral. You don't want to take anything like what you describe. Unfortunately you cannot just go pick up either of these items. They have to be ordered. J Crows has a website which sells it, as does
Science company and
Science stuff. I get mine from
Science company.
I apologize for J Crows' rudeness. We are not normally like that here. To his credit, he has some good information about
Iodine on his site.
Keep reading, go back to the earlier pages, especially the R and RN posts. When you are ready to order, check out the posts on the various companies that sell it.
