Lithium (Low-Dose)

Lithium is a naturally occurring trace mineral found in varying amounts in drinking water and certain foods, and at low doses it has attracted growing research interest for its potential role in brain health. Studies indicate that low-dose lithium may support neuroprotection by promoting the production of brain-derived neurotrophic factor and inhibiting glycogen synthase kinase-3, enzymes involved in neuronal stress and inflammation. Research suggests that populations with higher natural lithium levels in their water supply tend to show lower rates of cognitive decline and more stable mood patterns, though these are observational findings. Commonly available as lithium orotate or lithium aspartate, low-dose lithium is being explored as a nutritional approach to supporting long-term cognitive function, though more controlled clinical trials are needed to fully understand its benefits.
