Introduction
Pure l theanine Powder, a unique amino acid found almost exclusively in the tea tree (Camellia sinensis), is becoming one of the premier natural compounds for reducing stress and anxiety. In green tea, L-theanine is the major amino acid accounting for 1 to 2% of the dry weight of the tea. The highly purified L-theanine in the dietary supplement is produced through a fermentation process that mimics the natural process of green tea leaves.

Benefits
● Pure l theanine Powder and Neuropsychiatric Disorders
L-Theanine has been shown to potentially improve learning, memory, and cognitive function, and enhance selective attention during mental tasks. Epidemiological studies have shown that regular consumption of tea made from the leaves of the Camellia sinensis tree may be associated with a lower incidence of cognitive decline. L-theanine may be a promising enhancement therapy for schizophrenia and may be beneficial for mood disorders, attention deficit hyperactivity disorder (ADHD), as well as panic, obsessive-compulsive disorder (OCD), and bipolar disorders.
● L-Theanine, Anxiety and Stress
The anxiolytic effects of L-theanine are mediated through different mechanisms, including elevating α-brainwave activity, increasing GABA synthesis, and its role as a weak antagonist of AMPA glutamate receptors . The general calming benefits of L-theanine are reflected in increased brain electrical activity in the alpha frequency range (8 to 13Hz). Changes in brain electrical activity measured by electroencephalography (EEG) were dose-dependent and resembled the beneficial EEG changes observed during meditation, including increased alpha waves in the occipital and parietal regions. After administration of a 200 mg dose of L-theanine, increased alpha activity was shown that may persist for 60 minutes, and this effect was more pronounced in individuals with higher trait anxiety. Finally, the study found that consumption of green tea high in L-theanine may attenuate adrenal hypertrophy in mice exposed to chronic stress.
● L-Theanine and Other Psychiatric Disorders
A placebo-controlled study found that taking L-theanine 100 mg twice daily may significantly improve sleep quality in boys with ADHD, suggesting that L-theanine may be an effective adjunct therapy for ADHD. L-theanine does not cause drowsiness, but taking 200 mg of L-theanine before bed may optimize sleep by relieving anxiety.
● L-Theanine Cerebrovascular Disease and Stroke
Results from animal studies suggest that L-theanine may help prevent cerebrovascular disease and lessen the effects of cerebrovascular accidents (ie, stroke). The neuroprotective effect of L-theanine after transient cerebral ischemia may be related to its role as an AMPA glutamate receptor antagonist. Rats treated with L-theanine (0.3 to 1 mg/kg) before undergoing experimentally induced repeated bouts of cerebral ischemia may exhibit a significant reduction in spatial memory impairment and a significant reduction in neuronal death.
Application
Pure l theanine Powder can be used in health food, cosmetics, nutraceutical, and pharmaceutical supplement. It has been studied for its potential applications in health and wellness, particularly its ability to reduce stress and improve cognitive performance. In terms of health benefits, research suggests that L-Theanine powder may help promote relaxation, support healthy sleep patterns, reduce anxiety and depression, improve attention span and memory recall, and enhance alertness without causing fatigue or drowsiness.
