L-theanine may help to reduce nervousness, in keeping with a 2016 study. Healthy members consumed a drink containing 200 mg L-theanine or a placebo. One hour after consumption, the stress response to a cognitive stressor was significantly reduced in those who consumed the L-theanine drink. Three hours after consumption, saliva cortisol (a hormone secreted in response to emphasize) was considerably lower.
Another examine explored the results of standard consumption of L-theanine and located that every day consumption decreased subjective stress and saliva ranges of α-amylase (an enzyme released in response to emphasize) in undergraduate students undergoing stress.
A preliminary research examined the effects of a low-caffeine green tea on sleep high quality (caffeine in green tea can intrude with sleep and may counteract the impact of theanine). After consuming a low-caffeine green tea each day for seven days, saliva alpha-amylase ranges were significantly lower in those that drank the low-caffeine green tea than in those that consumed the usual green tea. Sleep high quality was higher in those that had consumed a bigger amount of low-caffeine green tea.
A 2017 research published in Acta Neuropsychiatrica explored the use of L-theanine for main depression.
