L-Theanine 150mg L-Theanine 150mg

Doctor’s Best Suntheanine L-Theanine is a dietary supplement, in the composition of which there is a certified form of pure L-Theanine, isolated from green tea. It is a natural nootropic substance used to increase concentration and improve mental efficiency. Thanks to exceptional properties modulating alpha brainwaves, L-Theanine has a soothing effect on the nervous system and causes the state of relaxation.

The preparation is recommended to people exposed to large intellectual effort, living under large pressure and in chronic stress, which are negatively reflected in psychological well-being and mental efficiency. It alleviates negative emotions and relaxes, without causing sleepiness and fudding. Quite the opposite – it facilitates concentration, improves memory and strengthens cognitive functions. It allows to maintain the highest intellectual efficiency and good mood even in the periods of increased stress and tension.

L-Theanine is the most commonly used in supplementation and the easiest assimilable form of theanine for the organism – non-protein amino acid extracted from green tea (Camellia sinensis). When it comes to its structure, L-Theanine is analogous to glutamate and glutamine. It is quickly absorbed to the bloodstream and easily crosses blood-brain barrier, affecting various neurochemical parameters in the brain. It is a compound soluble in water, which does not accumulate in the organism, therefore overdosing L-Theanine is practically impossible.

Activity in the nervous system
L-Theanine demonstrates a rage of positive effects related to the work of the brain. The main mechanism of its operation includes the influence on the activity of brainwaves and the level of key neurotransmitters.

L-Theanine influences the creation of electric impulses on the surface of the brain, called brainwaves. It increases model intensity of alpha waves, which correlates with the feeling perceived as the state of relaxation with the simultaneous maintenance of alertness.

L-Theanine regulates the level of key neurotransmitters – dopamine and serotonin. Moreover, it increases the activity of gamma-aminobutyric acid (GABA). The balance of neurotransmitter concentration is the guarantee of mental well-being and positive mood, devoid of irrational anxiety or concern.

L-Theanine inhibits the arousal of adrenocortical glands. It maintains cortisol under control, positively modulating the response of the nervous system to stress.

L-Theanine is a good  base surface for glutamine transporters, therefore similarly to glutamine, it may have a positive influence on brain functions.

L-Theanine stimulates the release of proteins necessary for the growth of neurons. Additionally, it protects them from damage by blocking excessive stimulation of cells.

Benefits from supplementation
L-Theanine brings many benefits for psychological well-being, cognitive functions and general state of health. The main effects of using it is general feeling of calm and relaxation.

However, it is not related to excessive sleepiness, dopiness or distraction that usually accompany using synthetic sedatives. Quite the opposite – the growth and modulation of alpha brainwaves thanks to L-Theanine not only promotes relaxation, but also contributes to the increase of the level of concentration and alertness, sharpening senses and mind clarity.

In the opinion of its many users, L-Theanine is conducive to creativity and inspiration. It increases intellectual efficiency, improves memory and increases the pace of mental processes.

Many studies proved that L-Theanine facilitates learning. People taking L-Theanine achieved much better scores in tests checking the pace of knowledge acquisition and the ability to count that the group taking placebo.

L-Theanine decreases the response of the sympathetic nervous system during stress, thanks to which it noticeably reduces tension, anxiety and concern, which often accompany chronic stress.

L-Theanine has antidepressant effect. It is a precursor of serotonin, which constitutes the most important neurotransmitter from the point of view of psychological well-being.

Cooperation with caffeine
L-Theanine works synergistically with caffeine and both these substances mutually reduce their weak sides. Combining them brings about surprisingly good effects for mental efficiency and well-being.

Thanks to L-Theanine, caffeine stimulates, but does not cause jitteriness, nervousness or the feeling of anxiety, which are usually felt when it is taken solo. L-Theanine in turn, gains higher stimulation, motivation and the so-called “boost”.

It is a great news for the amateurs of „little black coffee” and the supporters of caffeine, who want to enjoy only the positive sides of its activity. It is possible thanks to the supplementation with L-Theanine.

Summing up, Suntheanine L-Theanine is revolutionary supplement, which allows to achieve seemingly impossible feeling of blissful peace and relax, simultaneously maintaining the sharpness of mind and concentration. At the same time, it is not burdened with any risk, connected to side-effects. It will work perfectly in the period of increased intellectual effort or chronic stress.
