PURE Theanine is a dietary supplement with the top-quality L-theanine. Each capsule provides as much as 500 mg of the active substance. The formula reduces mental tension and promotes relaxation without causing drowsiness. It helps maintain high intellectual performance and maximum alertness and focus even in very stressful situations.
L-Theanine is an easily absorbable and highly bioavailable form of the amino acid theanine. This compound is characteristic especially of green tea (Camellia sinensis) and found also in some species of fungi. It is a structural analogue of glutamate and glutamine. It crosses very easily the blood-brain barrier and does not accumulate in the body. This eliminates the risk of overdose.
L-Theanine has a sedative effect but not in the traditional sense. It does actually reduce greatly stress, tension and anxiety, but without causing drowsiness, absent-mindedness and decrease in alertness which occurs often in sedation.
The basic mechanism of action of L-theanine correlates with the activity of brainwaves. These are electrical impulses on the brain area which get you into a specific state of mind. It has been observed in studies that L-theanine helps increase the standard alpha brain wave activity. At a sensory level, it is perceived as a sense of emotional balance and stability and mental relaxation, but with increased consciousness and focus.
In addition, L-Theanine regulates the concentration of important neurotransmitters which are critical to mental well-being. It maintains dopamine and serotonin levels and boosts GABA activity. Optimising the brain’s chemical balance ensures a good, stable
mood without unnecessary nervousness or anxiety.
Resistance to stress
L-Theanine may be helpful in the periods of excessive stress and unfavourable circumstances which affect adversely your mental and physical health. Supplementation with this compound helps reduce the main stress markers, such as heart rate, immunoglobulin A levels and alpha-amylase activity in the saliva. L-Theanine decreases the stimulation of the adrenal cortex and inhibits excessive cortisol secretion.
It has been shown in studies there is a correlation between L-theanine and the expression of genes responsible for symptoms of posttraumatic stress disorder (PTSD). It has been proven that L-theanine may contribute to changing the expression of genes at the level of mRNA transcription. This helps relieve PTSD symptoms and treat other disorders of the central nervous system.
Maximum mental performance
L-Theanine shows neuroprotective properties. It may help strengthen memory and stimulates creativity. A huge role is played by the aforementioned alpha brain waves, which make it easier to learn new pieces of information and perform complicated tasks that require focus.
In addition, L-theanine stimulates the activity of NGF and release of proteins which are necessary for neuronal development and growth. Owing to that, there is an improvement in memory and overall mental performance. According to the latest scientific theories, the functioning of memory depends also from dopamine levels and it seems that L-theanine stimulates effectively its production.
In placebo-controlled studies, individuals who took L-theanine got better results in memorisation and calculations. Users noticed that L-theanine supplementation promotes mental clarity, sharpens senses, increases alertness and improves focus. As a result, it makes intellectual effort much easier.
L-Theanine shows a wide range of health benefits. It has a cardioprotective effect. What is more, it encourages nitric oxide production, which has a beneficial impact on the condition of blood vessels and helps lower elevated blood pressure. It prevents also the oxidation of low density lipoproteins and thus reduces the incidence of atherosclerosis.
L-Theanine is a potent antioxidant. Studies evaluated its ability to, among others, protect liver cells against damage caused by excess free radicals. It turned out that oxidative damage to hepatocytes and inflammation reduced in rodents taking large doses of L-theanine.
Synergistic effects with caffeine
L-Theanine may be recommended to persons who consume often caffeine but do not respond well to it. Apart from boosting energy levels and focus, high caffeine doses cause also a dangerous increase in blood pressure, irritability and anxiety.
Adding L-theanine allows you to reduce negative effects of caffeine intake. Furthermore, it helps enjoy benefits of caffeine. The combination of both compounds gives a massive surge of energy, reduces drowsiness and fatigue, speeds up reflexes and strengthens considerably cognitive abilities. At the same time, it helps stay calm.
To sum up, PURE Theanine is an extremely interesting nootropic, recommended to persons exposed to great intellectual effort, especially associated with excessive stress and tension. The formula helps achieve the desired state of mind, namely mental relaxation combined with maximum focus.
L-Theanine belongs to natural substances and is believed to be a very safe and well-tolerated compound. The recommended dose should be taken on an empty stomach. The supplement’s effects are noticeable just after about 60 minutes and last for the next few hours.
L-Theanine acts in synergy with caffeine. It gives an interesting energising effect and sharpens your senses without overstimulating the body or causing anxiety, which may occur while taking high doses of caffeine.

L-theanine is an amino acid, not building proteins, occurring naturally in the dried green tea leaves, absorbed from the gastrointestinal tract, overcomes easily blood-brain barrier, affecting the nervous system and the relation between neurotransmitters (e.g.dDopamine, serotonin, gamma-aminobutyric acid), with a relaxing effect and increases the psycho-physical capacity, (concentration, memory, alertness). Recommended for use for people burdened with considerable physical effort, athletes of sport disciplines that require concentration and memory, also for students in the period before exams. Available in the form of mono-preparations and multi-component relaxing and post-workout anti-stress supplements..
Dosage: customarily used in supplementation 50-200mg per day
