Food supplement based on GABA (gamma-aminobutyric acid). Presentation: 60 720mg vegetable capsules. Net quantity: 43.20 g. Instructions for use: Take 1 capsule a day. GABA (Gamma-aminobutyric acid) is a neurotransmitter (like Serotonin or Dopamine) and therefore sends messages through the brain and nervous system. It participates in communication between neurons, reducing neuronal activity and playing an important role in behavior, cognition and the body's response to stress. GABA helps control fear and anxiety when neurons become overexcited.
