Calcium orotate, is a salt of orotic acid and calcium. It is available as the monohydrate, C10H6CaN4O8. In this compound, lithium is non-covalently bound to an orotate ion, rather than to a carbonate or other ion. It is marketed as a dietary supplement, though only barely researched between 1973-1986 to treat certain medical conditions, such as alcoholism, and Alzheimer's disease.

Calcium orotate is capable of providing calcium to the body, like lithium carbonate and other calcium salts.
