Thorne - PharmaGABA-250 60 caps

Contains natural-source GABA, a brain chemical to promote a calm state of mind and restful sleep* Natural-source GABA (gamma-aminobutyric acid) Gamma-aminobutyric acid (GABA) is a major calming brain chemical or neurotransmitter.* Clinical studies show that the natural form of GABA that is in Thorne's PharmaGABA can decrease the brain's stress-related beta waves and increase the production of its alpha-waves, creating a profound sense of physical relaxation while maintaining mental focus.*  Other studies have shown reduced pupil diameter, heart rate, and two natural biomarkers of stress – salivary cortisol and chromogranin A – all signs of relaxation.* In addition, studies also indicate GABA can enhance sleep.* In a head-to-head, double-blind trial of natural PharmaGABA versus synthetic GABA, the synthetic GABA did not demonstrate these positive effects.*  PharmaGABA-250 offers 250 mg of natural GABA per capsule, while PharmaGABA-100 offers 100 mg per capsule. Both are non-habit forming.
