Re: chloride vs. chlorine?

these are different right? So we should not worry about the chloride displacing our iodine?

A while back I discovered that potassium chloride helped me sleep better, one side effect from taking it was brown urine. Do you think this brown urine was because of the bromides? (I eat only whole foods such as fruits, veggies and nuts so I wonder where I might have picked up the bromide)
