L-Theanine is an amino acid found in green tea that produces calming effects in the brain by increasing levels of serotonin and dopamine, and blocks the binding of L-glutamic acid to glutamate receptors. A "feel good" supplement, L-Theanine causes no adverse reactions. In fact, in Japan L-Theanine is added to soft drinks and chewing gum for the purpose of inducing relaxation.
