food for thought:
When I saw Brownstein talk 2 years ago he said he took 50mg of Iodine for 4 years before his high level of bromide output dropped. He has the lab equipment for testing in his office so he was monitoring regularly.....
He also said when he goes below 50mg he doesn't feel as good and when he goes above 50mg he doesn't notice a difference. So he stays at 50mg.
I am only 6 months in so I can't comment from personal experience yet.
My bromide was high when I tested in February. So I am waiting for my new test results.
