GABA (gamma-aminobutyric acid) is produced by neurons in the brain, and functions as the principle inhibitory neurotransmitter.1 GABA is associated with the parasympathetic side of the autonomic nervous system, which balances the sympathetic (fight-or-flight) response. Many pharmacological agents exert anxiolytic, analgesic, anticonvulsant and sedative effects by modulating GABA receptor activity or increasing GABA availability.2,3 L-theanine is an amino acid found at high amounts in green tea. L-theanine may support relaxation and mood by increasing alpha-wave activity, brain serotonin, dopamine, and GABA levels, and by blocking the binding of L-glutamic acid to excitatory glutamate receptors in the central nervous system.4,5
Quicksilver's Delivery Systems™ GABA with L-Theanine brings you a highly absorbable form of GABA partnered with L-Theanine for optimal parasympathetic support. Conventional oral forms of GABA do not easily cross the blood-brain barrier.6 however the small liposomal delivery systems such as those utilized by Quicksilver Scientific have demonstrated this ability, producing a quick and powerful effect.
