Scientists Find Correlation Between Lithium in Drinking Water and Reduced Suicide Rates

A Japanese study has found a significant correlation between lithium levels in the water supply and reduced suicide rates. The new data is consistent with another study conducted several decades ago which produced similar results.

Scientists have described the findings as intriguing and have called for further study. In significantly greater doses lithium is used as a mood stabiliser. It is theorised that it may have cumulative effect through the water.

Any move to add lithium to drinking water is likely to provoke lively debate not dissimilar to discussions over the addition of fluoride to water. Researchers say the benefits could be significant but have called for caution and thorough research.
