I need the link to where salt loading causes a multiplication of bromide being excreted. I looked at the FAQs, but maybe I am in too much of a hurry. Can someone help?

Thanks. I need it for my cousin, who started very slowly on Iodine and is doing the salt once a day, but she got the impression it was more for constipation and since she has taken care of that, she is not doing the salt 2-3 times like when she started. I promised her the link - can't break my promise!
