The tap water we consume is comprised of various components, some of these are designed to make the water cleaner and clearer, whilst some, like fluoride, are added to improve the general public’s health. Most recently is the potential of Lithium, it is thought that Lithium could be added to water in order to improve mental health. Of course there are many variables that contribute to mental health, but lithium is currently used as a mood stabilising drug, usually for bipolar disorder.
Although doses would be very low, it is still anticipated that this addition will be controversial. What do you think?
