Terry,
The information I read is located at
http://www.breastcancerchoices.org/I...stigation.html. This site offers a Iodine Loading test to determine how much Iodine you secrete in your urine after you take the tablets. Please go to this site and let me know what you think about this info. This site offers a book by Dr. Brownstein. Is this the same book you are reading?
