Medical uses
In the medical field iodine is used as a disinfectant. Not having enough or too much iodine in your system can cause
goitre, which will enlarge your thyroid gland. As the thyroid gland is in your neck your neck will continually get larger. Iodine is put in salt to prevent iodine deficiency. Iodine is also used as a supplement in animal feeds to prevent thyroid deficiency. There is no substitute for many of the things that iodine is used for: inlcuding the nutrition it gives to the thyroid gland and its pharmaceutical use. Although as an ink it can be substituted for bromine and for disinfectant purposes it can be substituted for chlorine.
