Fluoride chemicals used for water fluoridation schemes
Are you "fluoride deficient"? According to various health organizations and data on diseases this is impossible. As to date there is no known biological process that requires the fluoride ion to function healthily even in trace amounts. The only known use of fluorine in any organism is as a defensive mechanism for one bacterium to kill another.
