Glutamic acid is a non-essential amino acid, meaning your body can synthesize it, so dietary intake is not always required. It plays essential roles in various physiological processes including:
Acting as a key excitatory neurotransmitter to stimulate and activate nerve cells in the central nervous system
Serving as a precursor to gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter that promotes relaxation and calm brain function
Participating as a vital component in protein and peptide synthesis
Adequate glutamic acid supports healthy brain signaling, balanced nervous system activity, protein metabolism, and even sensory functions.
Rich dietary sources of glutamic acid include: meats and poultry, dairy products, certain grains and vegetables.
