Lithium Orotate for Dementia | Evidence & Safety

Research on low-dose lithium and neuroprotection has raised interest in whether lithium orotate could play a role in cognitive decline and dementia. This page summarizes what the evidence says—and what it does not.

What the evidence says

Lithium (as prescription lithium carbonate) has been studied in bipolar disorder for decades. Some observational and preclinical work has looked at lithium and dementia risk or neuroprotection. Lithium orotate is a different salt form sold as an over-the-counter supplement; human clinical trials specifically for lithium orotate for dementia are lacking. A 2021 scientific review concluded that more research is needed on lithium orotate’s mechanisms and safety before claims about dementia can be made.
