I did not start consistently peeing brown until I reached 26mg...
Iodine IN SUFFICIENT DOSES will displace undesirable halogens...
J.C. Jarvis, M.D. (Folk Medicine, Henry Holt & Co., 1958, HB, p. 136), wrote:
"The clinical activity of any one of these four halogens is in inverse proportion to its atomic weight. This means that any one of the four can displace the element with a higher atomic weight, but cannot displace an element with a lower atomic weight. For example, flourine can displace chlorine, bromine and Iodine
because flourine has a lower atomic weight than the other three. Similarly, chlorine can displace bromine and Iodine
because they both have a higher atomic weight. Likewise, bromine can displace Iodine
from the body because iodine has a higher atomic weight. But a reverse order is not possible. A knowledge of this well-known chemical law brings us to a consideration of the addition of chlorine to our drinking water as a purifying agent. We secure a drinking water that is harmful to the body not because of its harmful germ content but because the chlorine content now causes the body to lose the much-needed iodine..."
BTW, Jarvis was wrong on a key point. A reverse order IS possible...iodine, in sufficient doses WILL elevate the excretion of bromide, for instance. voila! brown pee:)
