The Root Cause Medicine Podcast

James Greenblatt explores the evolving science of low-dose lithium as a neuroprotective intervention — highlighting its potential to prevent, slow, and even reverse cognitive decline associated with Alzheimer’s disease. He emphasizes that safe, nutritional lithium (2-10 mg) can support brain health by reducing neuroinflammation, promoting neuroregeneration, and stabilizing mood—without the risks associated with pharmaceutical doses. Clinicians are encouraged to assess lithium status through hair mineral analysis, monitor thyroid and kidney function, and consider environmental and dietary influences on endogenous lithium levels. By integrating low-dose lithium into a comprehensive, individualized care plan—including lifestyle modifications and targeted testing—practitioners can leverage this simple mineral to support mental clarity, impulsivity regulation, and long-term cognitive resilience.
