Don't you have to have the colored iodine to do that test? I do agree that iodine is certianly not a supplement you want to mess with since it works with one of the major glands, the thyroid. I just know that the first two days it made a difference in my energy levels and the third day I had that anxiety feeling, which I used to get when I had stimulants in my system which of course now I don't take any thing, not even vitaimins. The only thing I am taking right now is the dewormer and calcium balance. I thought the iodine would help with my metabolisim since I seem to loose weight slowly. I am trying to get my system back in balance after using a lot of stimulant type drugs in the past which have messed up my adrenals. Do you know how to do the iodine test? Someone told me a long time ago to put the red kind in the shape of a circle on your abdomen to see if it dissapeared. If it did in a certian period of time, it meant you were deficient. I guess I could try to do a search, huh? :)
