GABA (Gamma Amino Butyric Acid) is a key neurotransmitter, which actually blocks some neurotransmission leading to a less aroused nervous system. As a result GABA is considered a calming influence on the brain. Found in Kimchee, kefir, miso, sauerkraut, tempeh and yogurt and made in the brain, GABA is used for the management of anxiety, depression and insomnia as well as increasing human growth hormone.
