 General Info

Many of L-Theanine’s most powerful mental effects are created by limiting the neurochemicals which cause stress reactions and reduce mental clarity. For example, L-Theanine spurs the production of GABA, an amino acid which works to calm the mind and body by literally blocking the parts of the brain which receive stress messages.

L-Theanine also works to block L-glutamic acid from binding to glutamate receptors, reducing sympathetic nervous system “fight or flight” reactions. Glutamic acid is known as an excitatory neurotransmitter, and has been linked to seizures. By calming these over-stimulating chemicals, L-Theanine benefits can create broad feelings of relaxation and tranquility. These studies lead to the speculation that L-Theanine has the capability to mimic the functionality of glutamate, a naturally occurring bodily amino acid that assists in the transmission of nerve impulses in the brain.  Additionally, L-Theanine has demonstrated a capacity to increase dopamine levels in the brain, and contains a low affinity for NMDA, AMPA, and kainite receptors.
