Summary
L-Theanine is a unique amino acid present in ordinary tea leaves that has been proven to relax the mind without causing drowsiness.

When taken in combination with caffeine, L-theanine may relieve depression, enhance memory, focus, and overall cognitive performance.

L-Theanine is a recognized anxiolytic (anxiety reducer) that has been shown to improve the quality of sleep and positively affect both mental and physical stress symptoms by inducing a feeling of calmness and reducing heart rate and blood pressure.

Unlike some other natural anxiolytics such as valerian and hops, L-theanine does not act as a sedative that depresses central nervous system activity; on the contrary, it works by boosting levels of calming brain chemicals.

Studies show that it has enormous potential as a neuroprotectant that can help prevent oxidative damage in the brain, and may even help offset the cognitive decline associated with aging.

Benefits and Effects
L-Theanine provides a surprising array of benefits that can have positive effects both physically and mentally.

Reduces Stress and Anxiety
L-Theanine's ability to reduce anxiety, offset the physical effects of stress, and enhance feelings of calmness are among its most well-known benefits and are no doubt in large part responsible for the enduring global popularity of tea (which is the second most popular drink in the world after water).

Studies show that L-theanine effectively reduces concentrations of cortisol, often referred to as "the stress hormone," reduces both psychological and physiological stress responses,promotes alert relaxation.

Improves Memory, Attention, and Mood
L-Theanine's calming effects may have a variety of benefits, including boosting attention, focus, and learning ability through sensorimotor gating, or filtering environmental stimuli to prevent an overload of irrelevant information in the higher cortical centers of the brain.

Studies show that this "gating" effect reduces distraction and improves cognitive alertness, increasing the ability to focus and enhancing overall cognitive efficiency.

L-Theanine has been shown to be particularly effective as a nootropic when taken in combination with caffeine.

Combining the two eliminates the vasoconstrictive effect and behavioral effects of caffeine, thus improving cerebral blood flow and in turn enhancing cognition and mood.

The L-theanine-caffeine combination has also been shown to improve memory and selective attention and increase brain theta waves, which are an indication of cognitive alertness.

Improves Sleep
Research indicates that L-theanine is a safe, natural sleep aid that works by reducing anxiety as opposed to sedation.

L-Theanine has been shown to improve both the ability to fall asleep and the quality of sleep itself without causing daytime drowsiness or other negative side effects.

Reduces Blood Pressure
Oral administration of L-theanine has been shown to substantially lower both systolic and diastolic blood pressure. This effect was particularly pronounced among "high response" participants who demonstrated a significant rise in blood pressure in response to psychological stress.

Caffeine has been shown to elevate blood pressure during stress,but when taken in combination with L-theanine, caffeine did not increase blood pressure.

Because repeated temporary stress-related blood pressure elevation can lead to hypertension, L-theanine is believed to have some potential as a hypertension preventative for young adults who show a large blood-pressure response to psychological stress.

Improves the Effectiveness of Cancer Treatment
Research suggests that L-theanine may be a valuable adjunct therapy for cancer treatment.

Both human trials and animal studies show that theanine suppressed the growth of lung cancer and leukemia cells, enhanced the anticancer activity of cancer treatments such as trichostatin, and reduced cancer cell migration and invasion.

Research also suggests that L-theanine could be used as an effective chemopreventive agent for cancer.
