l-theanine from green tea
April 28, 2009 2:01 pm HealthGreen tea has long been known as a relaxing tea, and scientists now believe that both the flavour of green tea, and its relaxing properties, are due to its theanine content. Theanine seems to negate the stimulatory results of caffeine, which explains why folk drinking green tea often feel relaxed, in spite of the incontrovertible fact that it contains caffeine. The relaxing properties of l-theanine have been investigated in systematic studies. In one study, human volunteers demonstrated that l-theanine excites the production of alpha brain waves. These brain waves are abounding when relaxed, calm and lucid and are common in states of deep relaxation like during meditation. Inside thirty to forty mins participators in the study seemed to achieve a cool, yet alert mental condition, without sedation. Drinking green tea is so a good option for augmenting theanine in the diet.
However, the amount derived from green tea is comparatively tiny making l-theanine supplementation a good option for those wishing to increase their intake, and naturally for those that are not happy with the taste of green tea.
