Life Extension L-Theanine is a dietary supplement containing 100mg of L-theanine in one capsule. It should be added that it is not an extract from green tea leaves, but a product obtained during the patented process of fermentation, which imitates the natural one taking place in the plant. It is the purest, the most thoroughly researched with the highest quality L-theanine available on the market, containing 100% of this isomer.

It is worth to know that in present times of rather weak control over the supplementation market, a lot of products containing in its name „L-Theanine”, contains only half of this substance in the total product mass. The other half constitutes a totally different form, known as D-theanine, which was not properly researched and its usage is not recommended.

L-theanine used in the product Life Extension L-Theanine is the only pure form Suntheanine®, protected by 40 American and international patents. It was scientifically proven that it is a safe agent with a potentially interesting array of uses.

L-Theanine is an amino acid isolated from green tea (Camellia sinensis), which may cause calming effect in the brain. In Asian countries certain practices are used to enrich beverages and chewing gums with theanine in order to cause the state of relaxation. It is believed that, although this compound brings the feeling of relaxation, it does not limit the brain activity and does not cause sleepiness, which appears very often during using preparations of similar kind.

The abilities to learn
The research on rodents proved that theanine may increase the ability of learning and memory. The operation of this phenomenon mechanisms is attributed to “dampening” the part of the brain responsible for worrying. Thanks to this, we let our central nervous system rest and it is possible to use our resources more efficiently to develop the ability to focus and to gather our thoughts.

L-Theanine and gamma-Aminobutyric acid
As a glutamine derivative it exhibits certain structural similarity to this amino acid and to neurotransmitters for which it is a precursor (GABA, glutamate). Contrary to caffeine, L-Theanine may increase GABA amounts, which are said to let one rest better and elevate moods. Caffeine, on the other hand, causes the decrease of the available gamma-Aminobutyric acid in synapses, which may generate anxiety, nervousness and sleep disorders.

Alpha brainwaves
It is thought to be a compound with nootropic effect, which may calm down, decrease stress and anxiety and elevate mood. It seems that L-Theanine increases alpha brainwaves intensity used in fast-learning techniques. Such an effect may contribute to the advantageous increase of working productivity and learning effectiveness.

L-theanine and glutamate toxicity
During in-vitro research of growing cell neurons and in vivo research on rodents, theanine substantially reversed the toxicity induced by glutamate, which is a substance that is harmful to the human organism. It disturbs the activity of the cerebral cortex and artificially causes appetite stimulation. It may influence a limbic system, causing increased perspiration, stress relations, increased blood pressure, palpitations and migraines. Moreover, it limits perception, learning ability and concentration. Neuro-toxicity of glutamate may be one of the reasons for developing neurodegenerative diseases.

Thanks to the fact that Life Extension L-Theanine has nootropic properties, it is a product recommended to all the people, who are burdened with mental and physical effort. The product may be used by those, who are in the middle of the intensified studying periods (exams) or who perform intensive and long mental work (during big projects realization). It is also recommended to sportsmen, whose disciplines require concentration and good memory as well as to physically active people, whose regeneration may be disturbed by the effects of chronic stress and little sleep.
