As I said; it is the Iodine that replace the other halogens.
Boron cannot do it. But can help with the removal of fluoride, possibly. Via the calcium connection.
For bromide and chlorine, it is more the salt / chloride that helps.
I would love to link a good study about this, but I am afraid you are whipping a dead horse. The studies cost millions of dollars, who would finance such, when there is no patentable medication behind it?
