Thorne PharmaGABA – Natural GABA for Sleep, Stress Relief & Muscle Support Thorne PharmaGABA delivers a clinically studied, natural form of gamma-aminobutyric acid (GABA)—the brain’s primary calming neurotransmitter—to support stress management, restful sleep, focused relaxation, and physical performance*. Clinical studies show that natural PharmaGABA helps decrease stress-related beta brain waves while increasing alpha waves, creating a deep sense of physical relaxation without mental fog or sedation.* This unique brain-wave shift promotes calm alertness, making PharmaGABA useful both during high-stress periods and before sleep.* Additional research demonstrates measurable physiological markers of relaxation, including reduced pupil diameter, lowered heart rate, and decreased levels of salivary cortisol and chromogranin A, two well-recognized biomarkers of stress.* Studies also indicate that GABA can enhance sleep quality*. In a head-to-head, double-blind clinical trial, synthetic GABA failed to demonstrate these benefits, underscoring the importance of PharmaGABA’s natural, fermentation-derived form*. Muscle & Performance Support PharmaGABA has also been studied for its role in muscle development and recovery*. In a 12-week study, men who supplemented with whey protein plus 100 mg of PharmaGABA experienced a significantly greater increase in lean muscle mass compared to those using whey protein alone, when combined with regular strength training.* This makes PharmaGABA a valuable option for sports performance and recovery support*. Naturally Fermented for Superior Activity The natural GABA in Thorne’s PharmaGABA is produced through a fermentation process using Lactobacillus hilgardii—the same beneficial bacteria used to ferment cabbage in traditional kimchi. This natural production method is a key reason PharmaGABA performs differently than synthetic GABA.* Available Strengths PharmaGABA-100 – 100 mg natural GABA per capsule PharmaGABA-250 – 250 mg natural GABA per capsule Both formulas are non-habit forming and suitable for daily use.
