"The third item is one that I like to recommend, although there is very little literature on it, and that's simply a very small amount of iodine. It turns out that the prostate gland is the male body's second-greatest repository for iodine - after the thyroid gland, of course. In women, the second greatest accumulation of iodine is in the ovaries.
"It has been my clinical observation, not published in the scientific literature, that when women have low estriol and more estrone and estradiol - remember Dr. Lemon's theory that low estriol levels represent a cancer risk - added iodine helps to raise the levels of estriol and concomitantly lower the levels of estrone and estradiol (which are more procarcinogenic). I don't know how it works, but I've seen it work enough times since I first observed it in the 1970s that I know it's true."

"… 2 drops of the Lugol’s solution contains 5 mg of the reduced elemental form of iodINE (preferred by the breast, ovary and prostate) and 7.5 mg in the iodIDE form (preferred by the thyroid gland)."
