Raw Series L-Theanine contains 100 g of pure L-theanine powder. The amino acid is known for its unique mechanism of action which allows for reducing sleepiness, increasing tolerance to stress and stimulation of cognitive skills.
L-theanine – is an amino acid whose main sources are green tea leaves. It can be synthesised in the body system, however the produced amounts are insufficient. Its chemical structure resembles the structure of glutamine and its derivative, gamma-aminobutyric acid. Thanks to the significant influence on the functioning of the nervous system, it shows a wide spectrum of benefits, such as stress reduction, sleep quality improvement and increased cognitive skills.
The influence of theanine on the brain functions
L-theanine can cross the blood-brain barrier, which is why it is active within the nervous system. The amino acid affects the activity of discharges within the brain, introducing it into the stage of so-called alpha waves. They are associated with a high level of relaxation, open-mindedness, increased concentration and ability to memorise as well as better visual-motor coordination.
Theanine is also an antagonist of N-methyl D-aspartic receptors, which is why it shows neuroprotective properties. Activation of these receptors leads to the inflow of calcium ions into a cells and its increased sensitivity to neural stimuli. Their blocking, apart from the protection of neurons, is associated with reduced emotional tensions and antidepressant properties.
Regulation of sleep-alertness cycles
L-theanine has a unique influence on the state of allertness and sleep. Just after application, it shows sedative and relaxing effects, without causing sleepiness. On the contrary, it enhances cognitive skills, concentration and memorising. Used regularly, it positively affects sleep. It regulates circadian rhythm, and thus you can easily fall asleep in the evening, your sleep is deeper and theanine increases the frequency of REM phase.
Synergy with caffeine action
L-theanine perfectly complements coffee dose in the morning. In people sensitive to caffeine action, it reduces side effects of strong coffee, such as irritation or excessive stimulation. Moreover, it acts synergically towards cognitive skills, increases concentration and focusness. Combination of caffeine and theanine maximises the action of these substances, which makes them a perfect support in the period of increased mental effort.
Support for the cardiovascular system
Supplementation with L-theanine stimulates endogenous synthesis of nitric oxide, which is responsible for dilatating the vascular lumen. The amino acid phosphates the endothelium of eNOS enzyme, which leads to its stimulation and increased NO production. It allows for reduction in blood pressure and increases blood flow. It is associated with better blood circulation and nutrition of tissues, which can increase exercise capacity in athletes. Increased blood flow in tissues leads to faster regeneration.
Although L-theanine does not show antioxidant properties itself, it can reduce the level of free radicals in the body system. This activity is possible thanks to glutathione stimulation, which is the strongest endogenous antioxidant. Its increased synthesis significantly reduces the burden with oxidative stress.
To sum it all up, Raw Series L-Theanine is a product which will perfectly complement all kinds of supplementation. It will help to achieve maximal level of cognitive skills and facilitate memorising in students and pupils. It will support relaxation of stressed people without causing sleepiness and fatigue. Athletes could achieve maximal exercise capacity, both thanks to stimulation of the nervous system and improved blood flow. The product contains 100% pure L-theanine powder, which allows for precise dosing.
The optimal proportion of theanine to caffeine is 2:1. The dose of 300 mg of theanine and 150 mg of caffeine seems reasonable. This corresponds with two strong espressos or one coffee brewed with alternative methods which allow for achieving the strongest extracts.
To improve cognitive skills, e.g. during learning, theanine should be applied 45 minutes before you start your activity.
People with low blood pressure have to be particularly careful during theanine supplementation. L-theanine shows also synergy of action with blood pressure reducing drugs and can intensify their action.

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..
