About PharmaGABA

A naturally-sourced GABA

Gamma-aminobutyric acid (GABA) is a calming brain chemical – a neurotransmitter.* Clinical studies show that the natural form of GABA (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.*

PharmaGABA is produced via a fermentation process that utilizes Lactobacillus hilgardii, the same bacteria strain used to ferment cabbage in the preparation of the traditional Korean dish known as kimchi.

The Thorne Difference

Thorne uses patented PharmaGABA, a natural form of GABA, because it has been the subject of numerous clinical studies (see “The Science” below). Evidence indicates that PharmaGABA has superior benefits compared to synthetic GABA. In an unpublished, double-blind comparison trial, PharmaGABA, but not synthetic GABA, was shown to produce relaxation.* Relaxation measures included brain wave patterns, pupil diameter, heart rate, and reduction of the stress markers salivary cortisol and chromogranin A (a marker of adrenal stress).
