GABA (Gamma-Aminobutyric Acid) acts like a break to calm the nervous system. It also functions as a neurotransmitter, and is a significant inhibitor for reducing neuron and central nervous system overactivity, making you less impulsive. It promotes better sleep, improves mood, reduces anxiety and stress, and is a great supplement to take before bed to help with relaxation. GABA also stimulates neurogenesis (the creation of new neurons in the brain), to improve memory. GABA can help to reduce high blood pressure, and can help to alleviate many types of addictions - including sugar addiction. Without the proper amounts of GABA, our nerve cells would fire too often, creating a feeling of being on-edge, stressed and anxious; supplementing with GABA can help you to feel calm and relaxed. Additionally, GABA can help with ADD (attention deficit disorder); recent research has indicated that there may be a link between ADD and a deficiency of GABA. 100 capsules.
