Green Tea Visual Performance Randomized TrialBased on preclinical and clinical evidence, caffeine and-theanine are the two main constituents contributing to this effect [].1Mátyus Rebeka Olga (2025)Promising, but Not Completely Conclusive—The Effect of l -Theanine on Cognitive Performance Based on the Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Clinical Trials
Green Tea Visual Performance Randomized TrialCaffeine is a stimulant compound belonging to the group of methylxanthines and is found in several plants, including(coffee),and(guarana) [,].1Mátyus Rebeka Olga (2025)Promising, but Not Completely Conclusive—The Effect of l -Theanine on Cognitive Performance Based on the Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Clinical Trials
Green Tea Visual Performance Randomized TrialThe main constituents of the leaves are polyphenols, but other components such as methylxanthine derivatives (caffeine, theobromine, theophylline), organic acids, flavonoids, free amino acids (such as-theanine) and several flavor components are also present in fresh leaves [].1Mátyus Rebeka Olga (2025)Promising, but Not Completely Conclusive—The Effect of l -Theanine on Cognitive Performance Based on the Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Clinical Trials
