I take Iodoral (50mg total Iodine, 30mg as KI and 20mg as Iodine) orally whenever I have a "bug" that Vitamin C won't completely kill. Iodine kills both viruses and bacterias. It may also kills fungus. I use it to resolve dental infections (abscessed teeth), for example. My dentist said "You're a better man than I am" because he thought that I had suffered through abscessed teeth without treatment. I used Iodine and didn't tell him. Antibiotics don't work well whenever I have an abscessed tooth but Iodine sure does. I take one Iodoral a day with tooth problems but have taken two a day when more was needed.
I have also used Iodoral to kill infections in the mucus in my lungs. Vitamin C kills most of the infection but to kill all of it I need Iodine. Maybe some of the infection is caused by a bacteria?
Iodine works better than any antibiotic I have ever used. I use this source http://www.drbrownstein.com/Iodoral-p/iodoral.htm
This doc is a thyroid specialist and uses Iodine extensively in his practice. I do not have a thyroid problem.
