| Theanine Executive Function Randomized Trial | 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. | 2 | Baba Yoshitake (2021) | Effects of l -Theanine on Cognitive Function in Middle-Aged and Older Subjects: A Randomized Placebo-Controlled Study |
| Theanine Executive Function Randomized Trial | 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. | 2 | Baba Yoshitake (2021) | Effects of l -Theanine on Cognitive Function in Middle-Aged and Older Subjects: A Randomized Placebo-Controlled Study |
| Theanine Executive Function Randomized Trial | 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. | 2 | Baba Yoshitake (2021) | Effects of l -Theanine on Cognitive Function in Middle-Aged and Older Subjects: A Randomized Placebo-Controlled Study |
| Theanine Executive Function Randomized Trial | 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. | 2 | Baba Yoshitake (2021) | Effects of l -Theanine on Cognitive Function in Middle-Aged and Older Subjects: A Randomized Placebo-Controlled Study |
| Theanine Executive Function Randomized Trial | 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). | 2 | Hidese S (2019) | Effects of L-Theanine Administration on Stress-Related Symptoms and Cognitive Functions in Healthy Adults: A Randomized Controlled Trial. |
| Theanine Executive Function Randomized Trial | Stratified analyses revealed that scores for verbal fluency ( p = 0.002), especially letter fluency ( p = 0.002), increased after L-theanine administration, compared to the placebo administration, in individuals who were sub-grouped into the lower half by the median split based on the mean pretreatment scores. | 2 | Hidese S (2019) | Effects of L-Theanine Administration on Stress-Related Symptoms and Cognitive Functions in Healthy Adults: A Randomized Controlled Trial. |
| Theanine Executive Function Randomized Trial | This randomized, placebo-controlled, crossover, and double-blind trial aimed to examine the possible effects of four weeks L-theanine administration on stress-related symptoms and cognitive functions in healthy adults. | 2 | Hidese S (2019) | Effects of L-Theanine Administration on Stress-Related Symptoms and Cognitive Functions in Healthy Adults: A Randomized Controlled Trial. |
| Theanine Executive Function Randomized Trial | Participants were 30 individuals (nine men and 21 women; age: 48.3 ± 11.9 years) who had no major psychiatric illness. | 2 | Hidese S (2019) | Effects of L-Theanine Administration on Stress-Related Symptoms and Cognitive Functions in Healthy Adults: A Randomized Controlled Trial. |
