Hi, I just wrote in about how taking 3 sski (potassium iodide) pills a day cured my ovarian cyst in 3 weeks. I take it at night before going to sleep. I also wanted to report two other cures. One, I have lost weight without trying to on this supplement! 4 pounds to be exact. I really feel it speeds up my metabolism. I have tried to take apple cider vinegar for weight loss and it didn't do much for me. But after taking sski steadily for the past 6 weeks (since October), I can really feel a difference if I forget to take the supplement. It's weird and hard to explain, but food feels like its moving "sluggishly" when I don't take the sski. Two, sski has helped cure the itchy, peeling rash around my nose that I have had for about 15 years. I forget the medical term for it, not eczema, but close. I have slight redness in the creases around my nose but no peeling, which is remarkable because it is usually getting really bad at this time of the year in the cold weather. I wonder now if this supplement can help cure a whole range of skin conditions. Oh one more thing. You definitely need to be careful not to take too much iodine. If I take 4 sski tablets, I wake up the next morning with a nasal drip and a slight headache. I read that this is a sign of too much iodine, so I cut back or skip an entire day's dose of sski when I get these symptoms. 2-3 pills a day seems to be okay for me. On the bottle it says not to take the supplement for more than 14 days in a row. So I think I will come off the supplement for a day or two each week. When I ran out and didn't buy anymore in the past my ovarian cyst came back within a month, so I don't think I will stay off for very long. Hope this info helps someone out there because I think it's a great supplement. Haven't tried kelp and I haven't tried Lugol's for a long period of time, so I can't comment on the differences between them.
