L-Theanine Cognitive Performance Meta-Analysis	The 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 [].	1	Mátyus 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
L-Theanine Cognitive Performance Meta-Analysis	By synthesizing molecular evidence from the BDNF/TrkB/CREB signaling axis and the Nrf2/NF-κB homeostatic switch, we demonstrate that this multi-target strategy offers a more robust path to neuronal resilience than traditional single-target approaches.	4	Cipriano GL (2026)	Phytochemical and Fungal Bioactive Compounds in the "Brain Health Triad": A Narrative Review on Neurostimulating, Neurotrophic, and Neuroprotective Synergy.
L-Theanine Cognitive Performance Meta-Analysis	This narrative review proposes the 'Brain Health Triad' as a novel integrative framework for neurorehabilitation and cognitive enhancement, built upon three interdependent biological pillars: neurostimulation, neurotrophy, and neuroprotection.	4	Cipriano GL (2026)	Phytochemical and Fungal Bioactive Compounds in the "Brain Health Triad": A Narrative Review on Neurostimulating, Neurotrophic, and Neuroprotective Synergy.
L-Theanine Cognitive Performance Meta-Analysis	We illustrate how the synergistic interplay between a 'core triad' composed of Hericium erinaceus , Bacopa monnieri , and L-Theanine targets these pillars with high specificity.	4	Cipriano GL (2026)	Phytochemical and Fungal Bioactive Compounds in the "Brain Health Triad": A Narrative Review on Neurostimulating, Neurotrophic, and Neuroprotective Synergy.
