Thorne PharmaGABA-100

Thorne PharmaGABA – Natural GABA Support for Sleep, Stress & Focus

Thorne PharmaGABA features a natural form of gamma-aminobutyric acid (GABA)—the brain’s primary inhibitory neurotransmitter—designed to support restful sleep, stress regulation, and a calm yet focused state of mind*. GABA functions like a neurological “brake,” helping quiet excessive brain activity and promote relaxation without sedation.*

Clinical research shows that the natural PharmaGABA used in Thorne’s formula can help reduce stress-related beta brain waves while increasing alpha waves, which are associated with relaxed alertness.* This shift supports physical calm while maintaining mental clarity—making PharmaGABA useful during periods of stress, before sleep, or when focus under pressure is needed.*

Additional studies demonstrate physiological signs of relaxation with natural PharmaGABA, including reduced pupil diameter, heart rate, and key stress biomarkers such as salivary cortisol and chromogranin A*. These findings support PharmaGABA’s role in promoting the body’s natural relaxation response.*

Importantly, in a head-to-head, double-blind clinical trial, synthetic GABA did not demonstrate the same supportive effects as natural PharmaGABA.* This highlights the importance of GABA’s natural fermentation-derived form.

• PharmaGABA-100 – 100 mg of natural GABA per capsule
