Description
L-theanine is an amino acid found most commonly in tea leaves and in small amounts in Bay Bolete mushrooms. It can be found in both green and black tea. L-theanine (or L-gamma-glutamylethylamide) was discovered in 1949. It exists only in the free (nonprotein) form. It is derived from the leaves of Camellia sinensis (tea) and 2 other Camellia species (Camellia japonica and Camellia sasanqua). This evergreen shrub or tree grows to over 9 m in height with dark green, serrated-edged leaves that are alternate and oval. Available as a dietary supplement, theanine is used to boost focus and concentration as well as to promote relaxation.
