What Is Lithium?
Lithium is a naturally occurring mineral trace element. In medicine, it plays a therapeutic role for mood disorders and has emerging interest for brain health and aging.
Types of Lithium Supplements
Lithium supplements come in two common forms: lithium carbonate and lithium orotate. You’ll find lithium carbonate in prescription medications for bipolar disorder at therapeutic doses above 300 mg. You’ll see lithium orotate offered as an over-the-counter micronutrient, typically in doses ranging from 1 to 20 mg. Research cited in publications such as Nutrients (2018) notes that supplemental lithium orotate delivers a much lower dose than psychiatric protocols.
Common Uses and Benefits
Lithium gets prescribed in psychiatry to stabilize mood and prevent manic episodes, with decades of clinical use documented (National Institute of Mental Health). Low-dose lithium, such as lithium orotate supplements, has gained interest for neuroprotective effects, supporting brain cell resilience and cognitive performance. Preclinical and observational studies report associations between trace lithium exposure and lower rates of dementia and neurodegenerative disease (Forlenza et al., 2014; Nunes et al., 2013).

Peter Attia’s Perspective on Lithium Supplementation
Peter Attia examines lithium supplementation with a focus on longevity, neuroprotection, and clinical evidence. He analyzes research on trace lithium intake, addressing both possible benefits and practical safety issues for healthy adults.
Safety and Dosage Considerations
You see Attia emphasize that safety considerations dominate decisions on lithium supplementation. He highlights that pharmaceutical doses—600 mg to 1800 mg lithium carbonate for bipolar disorder—differ substantially from the microdoses sometimes discussed for general brain health, typically between 1 mg and 5 mg elemental lithium daily. He warns that high prescription doses may cause toxicity, with symptoms like tremors, kidney strain, and cognitive changes, referencing FDA safety guidelines and clinical pharmacology reviews.
You notice Attia reviews population studies suggesting environmental trace lithium exposure from drinking water is associated with lower rates of neurodegenerative conditions, yet he cautions against extrapolating these findings to supplementation without robust randomized controlled trial data. He stresses that individuals evaluate kidney health, existing medications, and interactions before considering even low-dose lithium, citing American Society of Nephrology publications and advising physicians supervise any supplementation.
Potential Benefits Discussed by Attia
You get Attia’s summary of emerging evidence showing potential neuroprotective effects of low-dose lithium. He discusses rodent studies where chronic trace lithium exposure protected against Alzheimer's-like pathology and improved memory scores. He cites epidemiological research from Japan and Texas, noting populations with higher natural lithium in drinking water showed lower suicide and dementia incidence, referencing JAMA Psychiatry and Translational Psychiatry articles.
You hear Attia explain that lithium’s mechanisms may involve anti-inflammatory activity, neurogenesis support, and inhibition of glycogen synthase kinase-3 (GSK-3), an enzyme linked to neurodegeneration and cell death. He clarifies that clinical trials in humans with low-dose lithium are limited and that current findings are preliminary, not definitive.
Scientific Research Supporting Lithium’s Effects
Extensive research explores lithium's neuroprotective, cognitive, and longevity-associated outcomes. Cellular, animal, and population data form the foundation for current claims.
Studies on Mood and Cognitive Health
Researchers examining lithium's mood-stabilizing effects focus primarily on high-dose prescriptions for bipolar disorder, as highlighted in meta-analyses (Cade, 2000; Malhi et al., 2017). Population-based analyses, such as Schrauzer and Shrestha (1990), connect trace lithium levels in drinking water with reduced suicide rates and improved mental health markers. Preclinical models reveal chronic low-dose lithium can preserve brain volume and neuronal integrity in rodents, supporting neurogenesis and memory function (Forlenza et al., 2012). In limited human studies, low-dose lithium (0.3 mg to 1 mg daily) delayed cognitive decline among elderly adults at risk for dementia, yet results remain inconclusive (Nunes et al., 2013).
Longevity and Aging Research
Animal studies link microdose lithium exposure with extended lifespan and age-related disease resistance (Zarse et al., 2011). Epidemiological findings from Japan and Texas suggest communities with higher environmental lithium experience increased longevity and reduced dementia prevalence (Oura et al., 2021; Kessing et al., 2017). Mechanistic data show lithium regulates key aging pathways, including GSK3β inhibition and autophagy, mirroring some caloric restriction effects in cellular models. Rigorous human longevity trials remain sparse, so associations can't confirm direct anti-aging benefits.

Risks and Side Effects of Lithium
Taking lithium, even at the low doses discussed for neuroprotection or longevity, carries known risks and side effects. Adverse effects depend on dose, duration, and individual factors such as age or existing kidney impairment.
- Kidney Function
Lithium can affect renal health. Chronic exposure, especially at higher prescription doses, sometimes results in nephrotoxicity or reduced glomerular filtration rate. Attia notes that microdoses show lower risk, but baseline and ongoing serum creatinine monitoring remains standard in clinical protocols.
- Thyroid Health
Lithium interrupts thyroid hormone synthesis and release. Rates of hypothyroidism increase in chronic users taking therapeutic doses. People with preexisting thyroid conditions carry higher risk.
- Gastrointestinal Symptoms
Nausea, diarrhea, and vomiting sometimes occur after lithium ingestion. Prescription lithium more frequently produces these effects; they’re rare with low-dose supplementation.
- Neurological and Cognitive Effects
Cognitive dulling and tremor commonly appear at therapeutic lithium concentrations. Cognitive impairment isn’t commonly linked to microdoses, but Attia underscores the need for more studies in aging populations.
- Electrolyte Imbalance
Lithium alters sodium and water regulation. Risk of dehydration or hyponatremia increases when combined with certain medications (such as diuretics) or coexisting health issues.
- Drug Interactions
Antihypertensives, NSAIDs, and some antidepressants raise lithium concentrations, amplifying risk of toxicity. Always assess current medication regimens before considering even low-dose lithium.
- Toxicity
Symptoms of acute toxicity include confusion, seizures, arrhythmias, and severe tremor, mostly at prescription levels. Microdose exposures haven’t shown major acute toxicity in studies, but no-dose safety is absolute.
| Side Effect | Typical Dose Range (mg) | Risk at Low Dose | Risk at Pharmaceutical Dose |
|---|---|---|---|
| Kidney dysfunction | 1-5 (microdose) / 600-1800 (Rx) | Low | High |
| Hypothyroidism | " | Low | High |
| GI distress | " | Very low | Mild to moderate |
| Tremor/cognitive blunting | " | Very low | Moderate |
| Electrolyte disturbance | " | Very low | Moderate |
| Acute toxicity | " | Rare | Moderate to high |
Attia advises medical supervision, baseline lab screening, and periodic monitoring when evaluating any lithium supplementation. Published research highlights the importance of tailored dosing and safety personalization based on individual biomarkers.
