L-Theanine is an amino acid that is found in tea leaves. It was identified in tea by Japanese scientists in 1949. While tea is the most common dietary source for L-Theanine, this compound is also found in some types of mushrooms. L-Theanine promotes relaxation and facilitates sleep by contributing to a number of changes in the brain. L-Theanine elevates levels of GABA, as well as serotonin and dopamine. These chemicals are known as neurotransmitters, and they work in the brain to regulate emotions, mood, concentration, alertness, sleep, appetite, energy, and other cognitive skills. Increasing levels of these calming brain chemicals promote relaxation and can help with sleep.
