L-Theanine

Active Mind supplement formula – L-theanine

Tea next to coffee is one of the most consumed drinks around the world. Thousands of people each day treat themselves with an infusion of leaves of various varieties, which, depending on the place of harvest, are characterized by a different taste and aroma.

Although tea is rather a drink associated with social gatherings or long evenings, in reality it works well in other situations. It is known for a long time that, for example, green tea is a source of antioxidants and polyphenols that fight unfavorable oxygen free radicals.
In turn, its red variety is often recommended during slimming and weight control. In fact, tea and coffee have many more similarities than you might think.

What is L-theanine?

The name L-theanine (Camellia sinensis) refers to an active chemical compound that is classified as a group of non-protein amino acids. It is also a derivative of L-glutamic acid, which is the source of the “umami” taste of one of the five base flavors felt by the human body. L-theanine is a compound primarily from the presence in tea leaves, which are its main source for the daily diet. It corresponds to about half of the total content of all amino acid compounds that we find in tea. The sun’s rays affect the transformation of L-theanine into the form of catechins and polyphenols, which are components included in the group of antioxidants.

It is worth noting that L-theanine is accumulated primarily in green and non-fermented Chinese tea – this process causes the aforementioned transformation. In addition, this substance is found in brown boletus and other tea species, including small camellia and Japanese camellia.

What are the properties of L-theanine?

Specialists categorize L-theanine as one of the natural and safe active ingredients that has nootropic effects. The real impact of the “tea amino acid” on the functionality and activity of the brain means that the work of the nervous system during the period of increased psychophysical involvement will be carried out in the right way. Of course, this is just a part of the multidimensional interaction of L-theanine, which through regular supplementation turns out to be a real support for mental performance and a number of other and equally important processes.

Effects on the content of neurotransmitters

There are speculations that the use of L-theanine may prove beneficial for maintaining optimal content of some neurotransmitters. According to experts, the amino acid found in tea leaves probably allows an increase in the concentration of serotonin, which promotes a state of relaxation and allows you to maintain well-being and help the body during periods of high psychophysical fatigue.

However, it is worth knowing that L-theanine is extremely beneficial in inhibiting the properties of toxic glutamate. This compound leads to a decrease in the total level of glutathione, which is one of the strongest and most important antioxidants of the human body. Therefore, it is not without reason that it is talked about as a component limiting premature aging of the body and being an element of prevention for some cells against dangerous cancerous changes.

Protection of the state of nerve cells

The above-mentioned properties of L-theanine in stabilizing the level of glutathione is also part of the neuroprotective effect. The influence of the amino acid on the antioxidant potential in the body helps reduce the adverse effects of free oxygen radicals and glutamate, which is mentioned earlier, which is one of the elements of effective prevention of damage to neurons or entire neural connections. L-theanine supplementation is often recommended for improving some neurological functions and protecting against neurotoxins that can lead to the development of serious diseases.

Impact on cognitive functions

The similarity of L-theanine and caffeine is not only due to their presence in popular drinks. Both components show beneficial properties for normal cognitive functions, while theanine does not present such an intense stimulant effect. Tea amino acid turns out to be valuable for optimal memory work or learning ability. It is worth noting, however, that L-theanine helps put the body in a relaxed state – it provides adequate calmness with excessively interacting stimuli, and also promotes concentration.

Increased adaptation to stress and excessive nervous tension

L-theanine supplementation has an extremely valuable effect on reducing the perceived stress, and also helps the body achieve the right balance at the level of emotions and mental health. Specialists point out that regular administration of L-theanine can reduce glutamate transport, which is one of the effective elements to reduce brain stimulation and normalize its excessive activity.

Another important issue is the effect of L-theanine on increasing the total level of GABA – ɣ-aminobutyric acid – which is an extremely important neurotransmitter. Maintaining optimal GABA concentration enables the body to easier falling asleep, less fatigue caused by a high degree of nervous excitability, helps reduce the persistent consequences of exhausting physical activity.

Other properties of L-theanine

  • It shows a beneficial effect on the work of blood vessels and prophylactically reduces the risk of certain cardiovascular diseases
  • It may prove valuable for reducing the amount of fat around the abdomen
  • It promotes the normalization of cholesterol levels by limiting some of the adverse changes in the vessels
  • It supports the work of the immune system and may promote faster recovery, e.g. after some surgical procedures
  • It reduces the risk of liver damage and increases the activity of its enzymatic components

Why was L-theanine included in the Labosal Active Mind product?

The use of L-theanine in the Active Mind preparation by Labosal has its justification primarily in the properties of this ingredient. The amino acid derived from tea leaves has valuable meaning for memory work, focus, good mood, and also helps calm the body. It does not show strong stimulating properties, although it is great for supporting cognitive functions. Therefore, with a clear conscience, it can be an alternative to highly stimulating caffeine. What’s more, L-theanine is great for protecting neurons against oxidative stress and can be part of the safe prevention of neurodegenerative diseases. Combined with other ingredients, it will make our nervous system and psychophysical fitness gain proper support for everyday functioning. Therefore, choose wisely and wisely – preferably with Labosal Active Mind!
