L-theanine, 5-hydroxytryptophan (5-HTP), and melatonin have each been shown to independently improve sleep quality and quantity and/or decrease 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 the neurotransmitter levels of dopamine, gamma-aminobutyric acid (GABA), serotonin, norepinephrine, and glutamate. These effects result in a significant increase in alpha brain wave activity, indicating a state of wakeful relaxation, increased performance under stress, improved learning and concentration, and decreased anxiety.

5-HTP is the intermediate 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.

Melatonin is also closely related and is formed by the conversion of serotonin in the pineal gland under low light conditions. Known for regulating many biological rhythms, including the circadian cycle, melatonin has shown clinical benefits for inducing sleep or adjusting sleep cycles. Randomized trials have shown it to reduce sleep latency and improve perceived sleep quality, without impairing daytime psychomotor performance.
