Glutamic acid, also known as glutamate, is an amino acid that is used by the body to build proteins. According to the University of California San Diego, glutamate is the most common stimulating neurotransmitter in the central nervous system of the body. They go on to state that most people do not require glutamic acid supplementation because an adequate amount of the amino acid can be found in high protein foods like fish, dairy, eggs and meat.
