L-Theanine 500mg – 60 tablets

L-Theanine: amino acid from the leaves of the tea plant for inner harmony and high productivity

Everyone experiences stress differently. But what is stress exactly? The Austro-Canadian researcher Hans Seyle defined it as “an unspecific response of the body towards a demand”. In the 1930s he developed the basics of the science of stress. He wrote more than 1700 papers and 39 books about the subject “stress”.
Originally, Seyle called the negative stress component distress and positive stress eustress. The stress reactions of the body are not harmful to health per se and the periodic course of symptoms is often experienced as pleasant and performance enhancing, but sometimes as unpleasant and crushing. Stress reactions always depend on the individual perspective from those who are experiencing it.

L-theanine against stress

Luckily, there is an herb against stress, for example the green tea. Its leaves contain the amino acid L-theanine, which is able to cross the blood-brain-barrier and which plays a role in the transmission of nerve impulses in the brain.

L-theanine is an amino acid, which isn´t a component of proteins. It can be found in the leaves of the tea plant, but in brewed green and black tea the effect of L-theanine is balanced out or displaced by the caffeine.

L-theanine is also described as a neuro-modulator, because it increases serotonin and dopamine and has soothing properties without making you tired.

L-theanine is an adaptogen

Additionally, the amino acid is a popular reliever in unpleasant situations, you´d rather run away from. No matter if it is a speech in a packed meeting or the daily elevator ride to the 20th floor.

L-theanine has adaptogenic properties. It balances the mental mood by promoting the concentration if required, but it also gives tranquillity when everything becomes too much. Depending on the situation, L-theanine is able to combine these two properties.
