L-Theanine 500mg – 60 tablets

L-Theanine: amino acid from the leaves of the tea plant

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.

Green tea

Its leaves contain the amino acid L-theanine, 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.

Natural adaptogen

This means that the plant adapts to the conditions. It aims its effect exactly at where the body has a weak point and applies its power there. This also means that L-theanine can act very differently in different people. Adaptogenic also means that the plant does not add any new components, such as side effects, stress, etc.
