Iodine deficiency
Iodine deficiency is also linked to weaker (less detectable) forms of bromism. Iodine and bromine are closely related to each other in behavior and thus location on the periodic table, and high levels of bromine will displace iodine in tissues and blood when there is an opportunity to do so. Supplementary intake of iodine should be preceded by a salt loading protocol, or consumption of dietary sulfur beforehand.
