you have a daily bromide intake, depending on your environment. fire retardants are the main culprit. all the new stuff like carpet and cars and pulic transportation and buildings. you can thank insurance companies for making their rates more expensive than the chemicals.
bromine comes off in layers as the Iodine level in the body rises. sufficiency of Iodine in the body can take up to three years to reach. that too is dependant on dosage.
even so, being fully sufficient and taking over a gram a day in iodine, if i go off it for more than two days i can get bromine detox upon resuming my dose.
our environment sucks. its full of shitty chemicals which are harmful to human (and everything else) health. the situation is much more dire than most people can imagine.
