Lithium
5-20mg
With meals
Lithium is a naturally occurring trace mineral present in varying concentrations in drinking water, grains, and certain vegetables. While high-dose lithium carbonate is a well-established psychiatric medication, low-dose lithium (typically as lithium orotate) has gained interest for its potential neuroprotective and mood-supporting properties at much smaller doses.
