Lithium Orotate Restored Memory and Reversed Brain Damage in Mice
In recent studies, a synthetic compound called lithium orotate has shown promising results in the prevention and treatment of Alzheimer's disease (AD). This compound, formed by combining lithium, a naturally occurring mineral, with orotic acid, a substance produced naturally in the body, has been found to reverse brain damage and restore memory in mice [1][3][4][5].
Lithium, a trace element found in various foods and drinking water, is known to have major natural dietary sources including cereals, potatoes, tomatoes, cabbage, and some mineral waters [6]. However, it's worth noting that lithium in drinking water is not effectively removed by conventional drinking water treatment processes [7].
The study from Harvard Medical School reveals that lithium naturally occurs in the brain and is essential for maintaining the normal function of all major brain cell types [8]. A deficiency of lithium in the human brain is one of the earliest changes leading to AD [9].
Lithium orotate crosses the blood-brain barrier and maintains stable brain lithium concentrations at low doses (5-10 mg elemental lithium daily) [2]. Compared to lithium carbonate, a common therapeutic lithium salt for bipolar disorder, lithium orotate better evades sequestration by amyloid-β plaques, enhancing its protective effects against AD pathology in mice [3][5].
Effective doses in mice were at micro or low doses far below those used to treat bipolar disorder—approximately one-thousandth the typical prescription lithium dose—to mimic natural brain lithium levels without toxicity [5]. Long-term treatment in mice showed no evidence of toxicity or organ damage at these low doses [2][5].
The recommended dosage in human supplementation based on available supplement products and preliminary human data is typically 5 to 10 mg of elemental lithium daily [2]. This mirrors doses used to achieve brain lithium stability and mood benefits in humans with a good safety profile at these low levels.
However, it's important to note that no clinical trials in humans have yet confirmed efficacy or safety for Alzheimer’s prevention or treatment specifically. Experts urge caution in extrapolating mouse findings directly to humans and emphasize the need for controlled clinical trials to determine optimal dosing and formulation in humans, long-term safety profiles in elderly populations, and actual preventive or therapeutic benefits against AD progression [1][3][4][5].
If considering supplementation, consultation with a healthcare provider is advised, especially for those on medications or with pre-existing conditions [2].
Across the United States, the prevalence of dementia and Alzheimer's disease varies significantly. For instance, Florida has one of the highest rates, with approximately 12.5% of Floridians aged 65 and older having Alzheimer's disease [10]. In contrast, the dementia rate for the population aged 65 and older in Oregon generally ranges from about 9.0% to 11.0%, varying by county [11].
In regions such as Northwestern Texas, the dementia rate is higher than many areas but generally lower than Florida's dementia prevalence among those 65+ [12]. As research continues, the potential role of lithium orotate in preventing and treating Alzheimer's disease may become clearer, providing hope for those affected by this debilitating condition.
