Low-dose nutritional lithium is one of the most misunderstood-and most important-nutrients in modern medicine. This book brings clarity to a subject long clouded by stigma, confusion, and the conflation of pharmaceutical and nutritional forms of the same element. This book is not about replacing psychiatric medications or about a miracle cure. It is about science, restorative biology, and supporting the brain with a nutrient it needs to maintain balance, emotional regulation, cognitive resilience, and long-term stability. It is about the lithium revolution-and meeting the unique physical, mental, and emotional challenges of the 21st century.
