• L-Theanine (200 mg): A non-protein amino acid derived from green tea that supports stress response and improves attention and working memory without causing drowsiness; best results observed at 200–400 mg per day.*[1-8]
• GABA (550 mg): Naturally occurring inhibitory neurotransmitter shown to promote relaxation and sleep quality in human trials; may act through gut-brain pathways.*[9-15]
• 5-Hydroxytryptophan (100 mg): A direct precursor to serotonin, 5-HTP supports the production of sleep-regulating neurotransmitters and melatonin.*[19]
• Vitamin B6 (10 mg as P5P): The active form of B6 is required to convert 5-HTP to serotonin and has been associated with healthier sleep duration and lower daytime sleepiness.*[16-18]
Ideal for individuals experiencing occasional stress or difficulty falling asleep due to lifestyle demands, stress, or irregular routines.*
Zen Sleep provides research-informed doses of L-theanine as well as GABA and precursors to serotonin and melatonin.*
