GABA Oolong can increase the natural levels of Gamma Amino Butyric Acid (GABA) in the body. Under typical conditions, tea is oxidized with oxygen (aerobic), producing glutamic acid in the tea leaves. Processed anaerobically with nitrogen (instead of oxygen), nearly all glutamic acid is replaced with GABA. A naturally occurring amino acid in your body, GABA aids the central nervous, immune, and endocrine systems. GABA reduces neural excitability throughout the nervous system and is also directly responsible for the regulation of muscle tone. Finally, GABA Oolong is rich in antioxidants, which can help keep free radicals at bay in our bodies. Plus, this oolong tea may help reduce overeating due to stress.
