Researchers at the University of Copenhagen have discovered that long term exposure to higher levels of lithium in drinking water appears to be associated with a lower risk of developing dementia. The relationship is non-linear in nature, however, for some unknown reason:
“The highest levels cut risk, but moderate levels were worse than low ones”.
Further research is required to explore the potential benefits (and harms) of lithium microdosing.
