L-Theanine
Camellia sinensis is a flowering plant whose leaves are most commonly used to prepare green tea, but can be fermented and oxidized to produce a variety of dark and white teas. In 1949, theanine was first discovered as the main component of freshly brewed tea, and its pharmacological effects have been extensively studied since then. However, L-theanine, the biologically active levorotatory enantiomer, can only be produced by extraction from natural sources. The dextrorotatory enantiomer is often found in competitors' chemically synthesized products and, even if they are technically pure, does not exhibit the full benefits of L-theanine. The L-Theanine produced by Botaniex is 100% natural.

Mechanisms
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-amino butyric 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 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
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.
