Harmony of Anti-Anxiety, Relaxation, and Sleep NutraceuticalsThis unique formula specifically targets these pathways to turn down your brain activity so you can slip into deep relaxation and restful sleep.
GABA and Glycine are the two most important inhibitory neurotransmitters. They calm your mind and have a powerful role in managing anxiety and stress. 
The amino acid Taurine stimulates both GABA and glycine pathways, so you can let go of that tension keeping you awake at night. 
Glycine can improve sleep quality and even reduce the effects of sleep deprivation  while Glutamine activates relaxation response in the brain and stimulates GABA production.
Pyroxidol 5-phosphate (aka activated vitamin B6) also helps your brain make GABA as well as melatonin, the sleep hormone. 
PLUS 5-HTP, the precursor to serotonin, which is involved with regulating your sleep cycle, mood, and sense of well- being.
And most importantly, 3mg of Melatonin, a scientifically proven dose of the sleep hormone shown to best aid deep sleep.
