What does the evidence say about Theanine Executive Function Randomized Trial?

The current Migaku evidence database contains 2 reusable source documents for Theanine Executive Function Randomized Trial. This answer focuses on benefits, uncertainty, and practical interpretation. - In addition, to investigate whether the single response was associated with cognitive function after regular ingestion, we compared the results of a single-dose and regular ingestion. [Baba Yoshitake (2021); evidence level 2] - A single dose of-theanine reduced reaction time in the attention task and increased correct answers and decreased the number of omission errors in the working memory task. [Baba Yoshitake (2021); evidence level 2] - α α 29 30 , 31 32 Studies that explored brain activity have previously reported that-theanine intake increases-wave activity.A study by Gomez-Ramirezfound that subjects who ingested 250 mg of-theanine had increased-wave activity for the attention task to be performed. [Baba Yoshitake (2021); evidence level 2] - 1 2 3 4 5 6 7 l l l-theanine is a nonproteinogenic amino acid contained in green teaand mushrooms.Among the different tea varieties in Japan, gyokuro and matcha contain more-theanine than sencha.-theanine affects brain functions.Studies in mice indicate that it improves behavior under stress conditions,suppresses deterioration of learning ability under social stress,and improves memory impairment. [Baba Yoshitake (2021); evidence level 2] - The PSQI subscale scores for sleep latency, sleep disturbance, and use of sleep medication reduced after L-theanine administration, compared to the placebo administration (all p p = 0.001 and 0.031, respectively). [Hidese S (2019); evidence level 2] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
