L-Theanine: What is L-Theanine and what does it do
L-Theanine is an amnio acid found in teas, particularly green and black tea. It has been shown to be synergistic with caffeine and possesses unique benefits of its own.
What L-Theanine does
Because it increases GABA, an inhibitory neurotransmitter, it can induce relaxation and decrease stress response. Therefore, L-Theanine can reduce both physical and mental stress. Stress is detrimental to cognition and by reducing stress response, one can retain their peak cognitive function during what would otherwise be stressful events. Chronic stress has a large toll on the body and can largely affect cognition in a negative manner. Some symptoms of chronic stress include:
- Intense mood swings
- Poor concentration
- Poor motivation to complete tasks
By reducing stress response, L-Theanine is able to effectively reduce or even eliminate the effects of chronic stress on cognitive functioning. As it also promotes relaxation, it can reduce anxiety and aid in sleep. Anxiety negatively affects mental performance, memory, and overall cognition. Sleep is also important for memory, learning, and overall cognition and poor sleep quality has been linked to decreased mental performance, increased sleep time, and poor energy upon waking up. Therefore, by promoting relaxation, L-Theanine is able to enhance sleep quality and reduce the effects of poor sleep quality on cognitive functioning.
How L-Theanine works
L-Theanine is an analog to glutamic acid as well as glutamine and readily crosses the blood-brain barrier. There, it increases dopamine release in the brain and increases overall levels of the inhibitory neurotransmitter, GABA, which induces relaxation and helps prevent insomnia.
L-Theanine is remarkably safe and there have been no reported side effects from its use. Even at extremely high doses, it is still safe and shows little to no harmful psychological and physical effects.
