Momentous L-Theanine delivers 200mg of pure L-Theanine per capsule — the amino acid found naturally in green tea that produces a state of alert relaxation characterized by increased alpha brain wave activity, reduced stress and anxiety responses, and improved cognitive focus without sedation or stimulation. Widely used alone or combined with caffeine for enhanced cognitive performance.

L-Theanine crosses the blood-brain barrier and modulates several neurotransmitter systems: it increases GABA, serotonin, and dopamine levels while reducing excitatory glutamate activity — producing the calm-but-alert mental state associated with green tea consumption. EEG studies consistently show increased alpha wave activity within 30–40 minutes of L-Theanine ingestion, correlating with the subjective experience of relaxed focus. When combined with caffeine, L-Theanine attenuates caffeine-induced jitteriness, anxiety, and heart rate elevation while amplifying the cognitive-enhancing effects — a synergy supported by multiple double-blind clinical trials. 200mg is the most-studied single dose. NSF Certified for Sport. Available at Beauty Riche with same-day shipping.
