Discovered in 1949 as a component of green tea, L-Theanine is an amino acid analog of the proteinogenic amino acids L-Glutamine and L-glutamic acid. It was then further isolated from the leaves of the Japanese Gyokuro tree. Traditionally, the leaves were brewed for a green tea known to promote relaxation and mental clarity. It can also be found in specific species of fungus as well as, in small amounts, other plants. For centuries, followers of Chinese traditional medicine have used green tea to promote health; physical and mental. Due to the infrequent presence of L-Theanine in our everyday diet, the western world has difficulty reaching a therapeutic level of L-Theanine.
