In order to actively and productively train, solve flow problems, you need adequate brain work. L-theanine is a substance that, in collaboration with caffeine, improves cognitive functions. Also, it is used to combat depression and anxiety. Due to its special properties, it increases stress resistance. The ESN online store has prepared a review of this amino acid. Well, let’s not waste time. Go!

The amino acid L-theanine is naturally found in tea leaves and edible mushrooms. It is also found in large quantities in green tea. It has been a fundamental pillar of Chinese medicine for over three millennia. It is used by doctors both in combination with other herbs and as a strong drink to increase stamina and concentration. The amount of L-theanine depends on the geographical location of the tea plantations, production methods and harvest time. In some types of tea, for example, in Camellia sinensivar (a species of the genus Camellia of the tea family), L-theanine is contained in a higher concentration than in the familiar camellia sinensivar tea plant. There is also a synthetic form of L-theanine on the market. It mixes with caffeine 1:1. A special drug to improve attention and concentration can be ordered from the ESN online store.

L-theanine is widely used in Asian countries to treat a wide variety of illnesses and mental disorders. It is becoming more and more popular in the West. The other main component of tea, caffeine, increases the concentration of acetylcholine and dopamine in the brain. This leads to improved attention, cognitive functions and mood. Caffeine has a positive effect much faster than L-theanine because it is absorbed faster, reaching peak plasma concentrations 30 minutes after ingestion. In comparison, peak plasma levels of L-theanine are reached 50 minutes after ingestion. In addition to L-theanine and caffeine, tea leaves contain other substances that have many beneficial properties. Including: amino acids glutamine, arginine, serine and alanine. As well as phenolic compounds: epigallocatechin, epicatechin gallate, epicatechin and epigallocatechin gallate (the so-called “catechins”). Special preparations based on caffeine and L-theanine can be ordered from the ESN online store.

Matcha is a special green tea product with a higher (compared to regular green tea) content of beneficial phytochemicals.

Animal and human studies confirm: L-theanine reduces the subjective response to stress, improves cognitive function, improves sleep quality and protects the body from the development of chronic diseases. Such as: cardiovascular, obesity and SARS. Various components of green tea, including L-theanine, caffeine, and catechins, may help prevent metabolic syndrome and obesity. Special preparations based on these components can be purchased at the ESN online store.

L-theanine reduces oxidative damage caused by reactive oxygen species. That is, free radicals. Increases the concentration of glutathione in the liver and the efficiency of liver enzymes. For example, superoxide dismutase. They are needed to remove toxins from the blood. Research results show that L-theanine has anti-aging properties. Preparations based on this amino acid can be purchased at the ESN online store. Green tea catechins may have beneficial antimicrobial and antiviral effects. Studies have shown that in the gastrointestinal tract, green tea activates intracellular antioxidants and inhibits the formation of procarcinogens.

L-Theanine: Prevention Of Cerebrovascular Accident And Stroke

Animal studies show that L-theanine may help prevent cerebrovascular disease and mitigate the effects of cerebrovascular accidents. This is the case, for example, for stroke. The neuroprotective effect of L-theanine after transient cerebral ischemia may be related to its activity as an AMPA glutamate receptor antagonist. Rats given L-theanine (0.3 to 1 mg/kg) before being repeatedly subjected to episodes of experimentally induced cerebral ischemia showed significantly less deterioration in spatial memory and significantly lower rates of neuronal death. Order L-theanine tonics from the ESN online store.

Finally, I would like to add: with the correct use of sports and special nutrition, health only improves. Of course, before buying, you need to consult with a specialist. Be healthy and happy!
