Gamma-
Aminobutyric Acid
A calming neurotransmitter supplement that may support relaxation, sleep, and healthy blood pressure.
Gamma-Aminobutyric Acid (GABA) is a neurotransmitter that helps inhibit nerve activity in the brain. While the body's own GABA reduces anxiety and promotes relaxation, supplemental GABA is used for stress relief, sleep, and possible cardiovascular benefits, though its effectiveness is limited by poor absorption into the brain.
Research shows modest effects for anxiety, sleep, and blood pressure, but oral GABA’s brain uptake and real-world benefit are limited by poor bioavailability.
May reduce anxiety and promote relaxation
LimitedSupplemental GABA may help lower feelings of anxiety and support a calm mental state.
May improve sleep quality and onset
LimitedGABA may help people fall asleep faster and experience better sleep quality, particularly in those with mild sleep disturbances.
Potential support for healthy blood pressure regulation
LimitedSome studies show that GABA supplementation or GABA-enriched foods may modestly reduce blood pressure, especially in individuals with mild hypertension.
