GABA. Gamma-Aminobutyric acid is an amino acid produced naturally in the brain. GABA functions as a neurotransmitter, facilitating communication among brain cells. GABA’s big role in the body is to reduce the activity of neurons in the brain and central nervous system, which in turn has a broad range of effects on the body and mind, including increased relaxation, reduced stress, a calmer, balanced mood, alleviation of pain and a boost to sleep.
Valerian extract. Valerian is most commonly used for sleep disorders, especially the inability to sleep (insomnia).
Chamomile. Chamomile has some unique properties that may benefit the quality of your sleep. It contains apigenin, an antioxidant that binds to certain receptors in your brain that may promote sleepiness and reduce insomnia, or the chronic inability to sleep.
