I can confirm that I didnt have much bromide detox symptoms until lately; after almost 3 years of Iodine supplementation.
If I take lets say 100 mg daily for a week I now get the typical bromide Acne on my forehead.
- or maybe it is my teens coming back, lol.
As far as I know I have not been exposed to bromides; so It must be in the air so to speak.
