Summary

Derived from tea leaves. Tea is native to eastern Asia and is a member of the Theaceae family. This evergreen shrub or tree grows to over 9 m in height and is pruned from 60 cm to 1.5 m for cultivation. Its dark green, serrated-edged leaves are alternate and oval, while its white and fragrant blossoms appear singly or in clusters.

An amino acid that is not common in the diet (not one of the essential amino acids or even one of the common nonessential amino acids) and is deemed a nondietary amino acid similar to L-Ornithine or L-Citrulline ,has structural similarity to glutamine and both neurotransmitters that are produced from it (GABA and glutamate) and is known to reach the brain and act in the brain following oral ingestion.

Function


1) Stress

May help reduce the negative effects of stress, according to a small study published in Biological Psychology in 2007. In an experiment involving 12 people, researchers found theanine-treated participants were less likely to experience an increase in heart rate when performing a stressful task.


2) Immunity

Taking green-tea-derived L-theanine and antioxidants in supplement form may help prevent the flu, suggests a study published in BMC Complementary and Alternative Medicine in 2011. Every day for five months, the study's 197 participants took either a placebo or a capsule containing L-theanine powder and catechins (a class of antioxidants found in green tea).


3) Brain Health

A 2010 study from Nutritional Neuroscience suggests that a combination of L-theanine and caffeine may help improve cognitive performance. For the study, 44 young adults took either a placebo or a combination of both of them prior to performing a demanding cognitive task. Researchers found that the combination of L-theanine powder and caffeine significantly improved accuracy and alertness and helped to increase focus while performing the task.

Additionally, findings from an animal-based study published in Free Radical Biology & Medicine in 2009 suggest that theanine may inhibit the buildup of amyloid-beta (a substance that forms the brain plaques associated with Alzheimer's disease).


4) Depression

The l-theanine powder may help relieve depression, according to an animal-based study published in phytotherapy Research in 2011. In tests on mice, scientists discovered that L-theanine powder produced an "antidepressant-like effect."


5) Weight Loss

The l-theanine powder shows promise as a weight loss aid, according to animal-based research published in the journal In Vivo in 2004. In an experiment involving mice fed green tea powder, researchers found that theanine and caffeine found in the powder appeared to prevent weight gain and fight the buildup of fat.


Application Area

1. Traditional uses

Discovered as a constituent of green tea in 1949 and was approved in Japan in 1964 for unlimited use in all foods, including chocolates, soft drinks, and herb teas, except infant foods. It also provides unique umami (brothy or savory) taste and flavor to green tea infusion.


2. General uses

May help relieve stress by inducing a relaxing effect without drowsiness and may also possess immunologic attributes. The l-theanine powder may also have effects on the cardiovascular system and play a preventative role in cancer; however, limited clinical information is available to support these claims.
