Introduction
L-Theanine is an amino acid commonly found in tea products. Usually found in dietary supplements, L-Theanine has shown promise in relieving anxiety disorders, lowers your risks of high blood pressure and helps prevent Alzheimer's disease.
GABA
One of the main ways that L-Theanine works is in how it affects gamma-aminobutyric acid (GABA). GABA is a chemical found in the brain that when released naturally creates a calm feeling in the body. L-Theanine increases the amount of GABA the body creates and distributes to the brain. The calming effect can be a great natural way to relieve some of the symptoms associated with anxiety.
Serotonin
L-Theanine also works by increasing the amount of serotonin that is made and distributed into the bloodstream. Serotonin works as a neurotransmitter for controlling emotions such as anger and happiness. The greater amount of serotonin in the body, the better ability you have to control your mood. This has helped in treatment of disorders such as depression and anxiety disorder.
Norepinephrine
L-Theanine also works by decreasing the amount of norepinephrine released in the body. Norepinephrine is a chemical that is produced when the body enters a "fight-or-flight" status. This also dramatically increases your blood pressure. Lowering the amount of the chemical in your blood can both help relieve anxiety, as well as hypertension.
