Glutamine is a naturally occurring amino acid. It is found abundantly in the central nervous system (CNS) where it participates in a variety of metabolic pathways. Glutamine is an important source of energy for the brain – It helps improve mental alertness, mood, and clarity of thinking.
In the brain, Glutamine is a precursor for two major neurotransmitters, glutamate and GABA (Gamma-aminobutyric acid).
Glutamate is the principal excitatory neurotransmitter in the central nervous system – It plays important roles in a wide variety of brain functions. At normal concentrations, glutamate is essential for brain functions such as learning and memory.
