Lithium Orotate
A low-dose, over-the-counter lithium salt marketed for mood, anxiety, and 'longevity.' Critically: there are NO randomized controlled trials of microdose lithium orotate for any outcome. The marketing borrows from trace-lithium-in-drinking-water epidemiology and the pharmacology of high-dose PRESCRIPTION lithium — neither of which validates the supplement. Lithium has a narrow safety margin and real toxicity, thyroid, and kidney risks.
What the evidence says
Most Lithium Orotate studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from medium-quality meta-analyses and randomised trials published 2007–2026 with a typical study size of 9 participants.

Lithium orotate is an organic lithium salt sold over the counter, typically supplying ~5 mg of elemental lithium per dose — far below the ~150-900 mg of elemental lithium in a therapeutic lithium-carbonate prescription. It is marketed for mood, anxiety, and longevity/neuroprotection. The honest evidence picture is weak: there are NO microdose lithium-orotate efficacy RCTs. The supporting arguments are indirect — (1) ecological/epidemiological studies associating higher naturally-occurring lithium in drinking water with lower suicide rates (with significant heterogeneity and publication bias), and (2) the well-established pharmacology of high-dose PRESCRIPTION lithium for bipolar disorder, plus emerging low-dose-lithium dementia research that explicitly calls for trials NOT yet run. A small 7Li-MRI pilot (n=9) confirmed that 5 mg/day lithium orotate produces detectable brain lithium, and a survey of supplement users reported perceived benefits but also more side effects and withdrawal than expected. None of this is efficacy proof. Lithium is a narrow-therapeutic-index agent: even though microdoses rarely reach toxic blood levels, lithium genuinely affects the thyroid and kidneys, interacts dangerously with common drugs (NSAIDs, ACE inhibitors, diuretics), and has documented supplement-overdose toxicity cases. This is a supplement that warrants real caution and medical oversight, not casual self-experimentation.
Lithium inhibits glycogen synthase kinase-3β and induces Bcl-2/BDNF signaling — demonstrated at therapeutic doses, extrapolated (unproven) to microdoses.
Preclinical low-dose lithium promotes neurogenesis and reduces oxidative stress — animal/mechanistic, not validated in human microdose trials.

Take with food
| Form | Type |
|---|---|
| 💊Lithium orotate (low-dose, with medical oversight) | Recommended |
| 💊Lithium aspartate (also OTC, similarly unvalidated) | Alternative |
Prescription lithium carbonate is a different, monitored medical product — do not conflate.
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: With food and adequate hydration; never combine with anything that raises lithium levels without medical supervision.
Dose-response data unavailable. The current published research for Lithium Orotate does not provide sufficient dose-specific outcome data to generate reliable dose-response curves.
Refer to the Dosage & Timing section above for recommended dose ranges based on available evidence.
There are no RCTs of microdose lithium orotate for mood, anxiety, or longevity.
Supplement-user surveys report perceived improvements in mood, anxiety, and cognition — uncontrolled.
Survey users reported side effects and withdrawal phenomena more often than expected.
Avoid — lithium is teratogenic (cardiac malformations) and passes into breast milk.
Avoid unless directed and monitored by a physician.
Do not combine without medical supervision — these can raise lithium to toxic levels.
Higher toxicity sensitivity and more polypharmacy — extra caution and monitoring.
NSAIDs reduce renal lithium clearance and can raise lithium to toxic levels — a classic dangerous interaction.
Reduce lithium excretion and can precipitate toxicity.
Tip: Reduce/stop dose; seek medical advice
Tip: Take with food
Tip: Periodic thyroid monitoring; discontinue if abnormal
Tip: Taper rather than stop abruptly; medical guidance
The best time to take Lithium Orotate is in the morning. Take it with food. Taken with food for tolerability; note there is NO efficacy-validated dose.
Lithium Orotate should be used with caution — talk to a healthcare provider before taking it. The most commonly reported side effects are tremor, nausea / GI upset, thyroid suppression (with sustained use). Use caution if any of these apply to you: Kidney disease or impaired renal function; Thyroid disease; Pregnancy and breastfeeding (lithium is teratogenic — Ebstein's anomaly risk).
Universal antioxidant that works in both water and fat, supporting blood sugar control, nerve health, and cellular energy.
Decrease renal lithium clearance, raising blood lithium and toxicity risk.
Additive serotonergic effects — theoretical serotonin-syndrome risk.
Lithium can suppress thyroid function; may interfere with thyroid management.
