I take 1/4 to 1/2 teaspoon of redmonds every day for adrenals. I take vit c daily too. 2-3G. Interesting theory though. Yours haven't gone then, with taking iodine.
I read somewhere about aloe vera being a cure for someone, it contains enzymes, vits etc and i read that one study done showed a lack of this certain enzyme in people with this, forgot which one now, begins with C. Also it boost the immune system and helps the digestive system. Worth a try. I did read though that vitiligo is definately not caused by a lack of vitamins/minerals etc. Not convinced about that.
There has been little research on this problem.
Thanks for your imput.
