L-Theanine
Camellia sinensis is a flowering plant whose leaves are most commonly used for the preparation
of green tea, but can be fermented and oxidized to produce a variety of dark and white tea leaves.
Theanine was first found to be a major constituent of fresh brewed tea in 1949, and since then its
pharmacological effects have been researched extensively. However, only extraction from natural
sources will produce L-Theanine, the left handed enantiomer which is bioactive. The right handed
enantiomer which is often found in competitor products which are chemically synthesized and do
not exhibit the full potency of L-Theanine’s collection of benefits even if they are technically pure.
Benifit of L-theanine
•Stabilizes mood
•Reduces chronic stress responses (both mental and physical)
•Reduces anxiety levels
•Improves cognitive function (memory, reaction time, and learning)
•Promotes alpha brain wave production (present during relaxed and calm mental states)
•Can naturally regulate blood pressure
•Alleviates some symptoms of schizophrenia
Mechanisms
Tea polyphenols are widely used in foods, cosmetics, supplements and pharmaceuticals.
Green tea catechins have shown a number of benefical effects, modern research and scientific data
demonstrates that the beneficial effects of green tea are largely due to its main catechin,
Epigallocatechin Gallate (EGCG). EGCG makes up about 30%-50% of the total catechin content
and has an antioxidant activity about 25-100 times more potent than Vitamin C and E.The
EGCG90%, 95% is a pure and defined substance delivering all the healthful benefits associated
with green tea, which provides the best of green tea in its purest form, is highly compatible with a
broad range of foods, beverages and dietary supplements. It is colourless and has little impact on

L-Theanine is an analogue amino acid to the proteinogenic L-glutamate and L-glutamine, two of
the twenty essential amino acids the body uses are precursors to protein synthesis. Once
L-Theanine is ingested, it is absorbed into the bloodstream through the small intestines and is able
to cross the blood-brain barrier intact, where it mediates an increase in levels of multiple
neurotransmitters. Serotonin, dopamine, glycine, and gamma-aminobutyric acid (GABA) levels
are all increased. Serotonin is central to regulation of mood, sleep, and learning. Dopamine is
utilized extensively in the central nervous system and is implicated the the regulation of motivation,
mood, and stabilization of muscle movements. Increased levels of glycine have been shown to
improve sleep quality in humans, and has been used as an effective add-on treatment for
schizophrenia. GABA is an inhibitory neurotransmitter that is shown to have a calming effect on
mood when present in the brain and is also directly responsible for muscle tone.
Safety
There have been no reports of adverse effects caused by the consumption of Tea Polyphenols
and Tea Polyphenols supplements.
Theanine has been approved for use in all foods in Japan, and is considered Generally Regarded as
Safe (GRAS) by the FDA. Independent studies on mammals such as rats have also found that even
extremely high doses of L-Theanine do not produce any negative physiological and psychological
effects.
Dosage
Typical dietary doses of L-Theanine range from 200-250mg/day,however doses as high as
1200mg/day can be used.
