GABA (Gamma amino butyric acid) is one of the non essential amino acid that is synthesized in the brain from another amino acid Glutamic acid. In brain GABA acts as a neurotransmitter (chemical messenger that transmits signals from one cell to another) that works efficiently for calming your mood and reduces anxiety. It also plays an important role in improving the brain functions. During the stressful situation GABA can recover the brain functioning by blocking the stress related messages that are reaching the brain hence GABA can be useful in decreasing the emotional stress and hypertension. GABA can also be beneficial in reducing the symptoms of hopelessness. GABA has been used to enhance the secretion of growth hormone from the pituitary gland (master gland of the body that affects secretion of most of the hormones). Since human growth hormone is involved in the fat metabolism its deficiency causes accumulation of fat around the hips and waist.
