The small intestine quickly absorbs ALL of the Iodine like a sponge and sends it into the blood stream to supply Iodine to every cell in the body. The cells of the body absorb Iodine with cell receptors designed to attract iodine. The immune system then ues this iodine to fight off & kill bad cells, fungus & disease. Unused iodine then goes through kidneys into the bladder. Even here, iodine kills kidney, bladder & UTI infections.
