Is there a connection between fluoride and hypothyroidism?
“Do you have any information on the connection between fluoride and hypothyroidism? In a publication entitled “Vitamins, Minerals and Supplements” by H. Winter Griffith, M.D., it states not to take fluoride if you have underactive thyroid function. I have not heard of this before and am wondering what the implications are.” ANSWER: Fluoride is a halogen like iodine and is therefore briefly picked up by the thyroid gland, but, unlike iodine, fluoride is not incorporated into thyroid hormone. It does NOT interfere with thyroid function in any way and there is NOT concern about using fluoride even if a person is indeed hypothyroid. This is, of course, particularly true if that patient is taking thyroxine, which is certainly not interfered with by fluoride or any other substance.
