L-Theanine, 5-hydroxytryptophan (5-HTP) and melatonin have all been shown to independently improve sleep quality and quantity, and/or lessen anxiety. L-Theanine is an amino acid found almost exclusively in tea, which influences the central nervous system through a number of mechanisms, primarily by influencing levels of the neurotransmitters dopamine, gamma-aminobutyric acid (GABA), serotonin, norepinephrine, and glutamate. These effects cause a significant increase in alpha brain wave activity, indicative of a state of wakeful relaxation, increased performance under stress, improved learning, and concentration, as well as decreased anxiety.

5-HTP is the intermediary between L-tryptophan and serotonin, a key neurotransmitter associated with sleep, mood and anxiety. 5-HTP bypasses the rate-limiting enzyme tryptophan hydroxylase, which normally limits the conversion of tryptophan to serotonin.
