Food supplement based on GABA (Gamma-aminobutyric acid). Presentation: 60 vegetable capsules of 720mg. Net quantity: 43.20 g. Directions for use: Take 1 capsule daily. GABA (Gamma-Aminobutyric Acid) is a neurotransmitter (like Serotonin or Dopamine) and therefore sends messages throughout 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.
