Hi, I am one of those people who have had great success with Iodine supplementation to cure uterine fibroids. I use Lugols solution, as it has more I2 than SSKI , and the I2 (elemental iodine) is really important for women with uterine fibroids or fibrocystic breast disease, (which I also had).
I started with 50mg Lugols per day (6-8 drops) in a glass of water, first thing in the morning. I did have a week or so of detox reaction, but upped the dose to 100mg per day, and these detox symtoms passed quickly. In a few weeks I saw dramatic reduction in my FBD, and the uterine fibroids started shrinking. After six months of Iodine supplementation most of the FBD was gone, and the uterine fibroids were almost gone. After 9 months, I had a breast examination and no FBD could be detected at all, I also had an ultrasound and no uterine fibroids could be detected either. My cycle is now normal, with no pain, and regular as clockwork.
As for buying iodine, that would depend on which country you live in.
There is a lot of info on this forum, and lots of women who have had success with uterine fibroids.
