Natural levels of lithium in drinking water help reduce suicides

Very low levels of lithium in drinking water may help prevent suicide in the general population, according to a new study. The study has prompted calls for further research into the possibility of adding lithium to drinking supplies – like water fluoridation to improve dental health.

Researchers at Oita University in Japan measured natural lithium levels in tap water in 18 communities in the surrounding region of southern Japan. Writing in the British Journal of Psychiatry, the researchers said: “Our study suggests that very low levels of lithium in drinking water can lower the risk of suicide. Very low levels may possess an anti-suicidal effect.”

And to think that my body was just getting used to being contaminated by the fluoride in our water supply.
