As far as cosmologists can tell, there were only three elements present when the universe was first formed some 13.8 billion years ago: hydrogen, helium, and lithium.
As one of the three original elements, lithium is found throughout our atmosphere. The sun, stars, and meteorites burn brightly with the gleam of this highly reactive element. 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.
