Kapusta ND, König D. Naturally occurring low-dose lithium in drinking water. The Journal of clinical psychiatry. 2015 Mar;76(3):e373-e374.
Recently, a series of ecological studies on antisuicidal properties of naturally occurring lithium contents in drinking water have sparked interest among researchers. In this issue, Ishii and colleagues present further argument for the hypothesis that even low lithium doses-or rather, doses of lithium at a supplemental level-might have their place in suicide prevention.With limitations, there is some evidence from randomized controlled trials (RCTs) supporting lithium in therapeutic doses as a suicide preventative in individuals with unipolar depression, bipolar disorder, schizoaffective disorder, dysthymia, or rapid cycling.
