This is part one of Dr. Greenblatt's Nutritional Lithium series. Part two can be found here.

On earth, lithium remains a major mineral component of granite rock, and also lingers in significant amounts in sea water, mineral springs, and soils. 

Lithium has also found its way into our cell phones, electric cars, and holiday fireworks. Every organ and tissue in the human body contains the mineral lithium, with particular importance in health, specifically brain health.

On the other, aggression is innate and essential to the human condition, even instrumental to our survival as a species for attainment of resources, determent of competitors, and organization of social hierarchies.

In part 1 of this series, we discussed the importance of correcting trace mineral imbalances of copper and zinc to reduce behavioral symptoms and improve medication efficiency in children with ADHD.
