The human pupil provides a rough measure of the degree of stress a person is under. When we are under stress, the pupil dilates. When we are relaxed and focused, the pupil relaxes due to activation of the parasympathetic nervous system. Because PharmaGABA^® activates the parasymptathetic nervous system, it has been shown to constrict pupil diameter and bring the body and mind into a state of increased feelings of relaxation with greater mental focus and clarity within 30 minutes after ingestion.

In a recent GABA’s sleep aid clinical study, PharmaGABA^® has shortened sleep latency, the time that takes a person to fall asleep and extended Non-Rem sleep time, the deepest stage of sleep. The increased Non-Rem sleep followed by an ideal sleeping rhythm through PharmaGABA^® results in the natural deep-sleep healing process.
