Overview

NOW Foods GABA provides 750mg of gamma-aminobutyric acid — the brain's primary inhibitory neurotransmitter responsible for calming neural activity. GABA supplementation is popular for promoting relaxation, reducing anxiety, improving sleep quality, and supporting growth hormone release. While there's debate about whether supplemental GABA crosses the blood-brain barrier, many users report noticeable calming effects within 30-60 minutes. The mechanism may involve GABA receptors in the gut-brain axis (enteric nervous system) rather than direct brain penetration.
