What is L-Theanine? L-theanine is an amino acid primarily found in green and black tea. In fact, as early as the 9th Century, Chinese Monk monks started consuming matcha (which contains high amounts of both L-Theanine and Caffeine) in preparation for long hours of meditation, which required them to be calm and focused. What is Caffeine? Caffeine is naturally found in tea, coffee, guarana and cacao plants. Coffee was reportedly discovered by an Ethiopian shepherd who noticed the extra energy the coffee bushes gave his goats after they grazed on them. In the modern day, billions of people consume caffeine when they wake up in the mornings or to get through an afternoon slump.
