Feature Summary

L-theanine, 5-hydroxytryptophan (5-HTP), and melatonin may help support relaxation and maintain sleep quality and quantity.* L-theanine is an amino acid found almost exclusively in tea,1 and may help support the central nervous system function.* L-theanine may also help maintain levels of neurotransmitters dopamine,2  gamma-aminobutyric acid (GABA),3,4 serotonin,5,6  norepinephrine,6 and glutamate7,8   already within the normal range.* Balanced neurotransmitters help support alpha brain wave activity, indicative of a state of wakeful relaxation, which may help maintain performance under stress, support learning and concentration, and maintain a calm mood.*1,9

5-HTP is the intermediary between L-tryptophan and serotonin, a key neurotransmitter associated with sleep, mood, and calm.*10,11,12  5-HTP bypasses the rate-limiting enzyme tryptophan hydroxylase, which normally limits the conversion of tryptophan to serotonin.13

Melatonin is also closely related and is formed by converting serotonin in the pineal gland when in low light conditions. Melatonin may help support biological rhythms, including the circadian rhythm, helping maintain healthy sleep cycles without impairing daytime psychomotor performance*14,15,16
