Promotes relaxation and supports natural sleep onset through clinically
studied L-theanine and melatonin precursors.*
Zen Sleep supports a calm, relaxed state and promotes healthy sleep
patterns by combining clinically studied nutrients that influence
neurotransmitter activity.*
It supports the stress response and provides
nutritional building blocks for serotonin and melatonin production.*
How It Works
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].
Who It’s For
Ideal for individuals experiencing occasional stress or difficulty
falling asleep due to lifestyle demands, stress, or irregular routines.*
