What the evidence says. Graded preliminary: lithium itself is a proven psychiatric drug, but no controlled trial has tested the low-dose orotate supplement for any mood or cognitive claim. The supporting human data are one uncontrolled 1986 case series plus ecological water-lithium and pharmaceutical-dose trials that do not apply to the doses sold. (Preliminary evidence: Early or small human trials; promising but not yet conclusive.)
What is Lithium Orotate?
Lithium Orotate (Lithium orotate) is a sleep and mood supplement used for marketed for mood & irritability. NutriDex grades the human evidence as Preliminary. Lithium orotate is an over-the-counter salt that delivers tiny amounts of lithium — roughly 0.13–0.19 mg of elemental lithium per 5 mg tablet, a fraction of the ~150–900 mg of lithium carbonate used in psychiatry. It is sold for mood, irritability and sleep, but no randomized controlled trial has tested the orotate supplement at these doses for any outcome. The human record is one uncontrolled 1986 case series in 42 people with alcoholism (150 mg/day) and indirect evidence: ecological studies link trace lithium in drinking water to modestly lower suicide rates (pooled effect inverse but heterogeneous), and pharmaceutical-dose lithium trials in mild cognitive impairment and Alzheimer's show some biomarker and clinical signals. Claims that the orotate form uniquely floods the brain rest on a 1978 rodent study and are unproven in humans. At marketed doses harm is unlikely, but efficacy is essentially unestablished.
Purported Benefits
✓Marketed for mood & irritability
✓Marketed for calm & sleep
✓Marketed for stress
✓Trace-dose lithium delivery
Evidence by outcome
The same supplement can be well-proven for one use and unproven for another — here is the human evidence graded outcome by outcome.
Supplements supply ~5 mg lithium orotate per tablet (~0.13–0.19 mg elemental lithium); no validated effective dose exists for the marketed mood claims.
Active Compounds
Lithium (Li⁺)Orotic acid (orotate carrier)
Safety & Cautions
⚠
At the trace doses sold (well under 1 mg elemental lithium), toxicity is unlikely and overdose case reports show only mild symptoms. However, lithium has a narrow therapeutic window and supplement labels are poorly standardized, so high or stacked dosing can cause tremor, nausea, thyroid and kidney effects, and serious toxicity. Lithium levels rise dangerously with dehydration, NSAIDs, ACE inhibitors/ARBs and thiazide diuretics, and it can worsen hypothyroidism; avoid in pregnancy and kidney disease. Anyone on prescription lithium, thyroid medication, or with renal impairment should not use it without medical supervision. Educational only — always check with your doctor or pharmacist before combining Lithium Orotate with any medicine.
Lithium Orotate is most often taken for Marketed for mood & irritability, Marketed for calm & sleep, Marketed for stress, Trace-dose lithium delivery. Low-dose lithium salt sold for mood — minimal human evidence.

What is the typical dose of Lithium Orotate?
Supplements supply ~5 mg lithium orotate per tablet (~0.13–0.19 mg elemental lithium); no validated effective dose exists for the marketed mood claims.
Is Lithium Orotate safe? Any cautions or side effects?
At the trace doses sold (well under 1 mg elemental lithium), toxicity is unlikely and overdose case reports show only mild symptoms. However, lithium has a narrow therapeutic window and supplement labels are poorly standardized, so high or stacked dosing can cause tremor, nausea, thyroid and kidney effects, and serious toxicity.
