L-THEANINE & CAFFEINE FOCUS SYNERGY
L-Theanine is a non-protein amino acid naturally found in tea leaves (Camellia sinensis). When paired with clean caffeine, L-Theanine promotes brain alpha-wave activity, yielding smooth, calm cognitive focus without nervous over-stimulation.
What Is L-Theanine?
L-Theanine is a unique amino acid that easily crosses the blood-brain barrier. It modulates neurotransmitter receptors (including GABA and glutamate), helping to mitigate peripheral restlessness and caffeine jitters while maintaining sharp visual attention.
THE ALPHA WAVE ADVANTAGE
Electroencephalogram (EEG) studies reveal that L-Theanine increases electrical activity in the brain's alpha frequency range (8–12 Hz). Alpha waves signal a mental state of "relaxed alertness"—the ideal cognitive baseline for high-level problem solving, coding, or competitive gaming.
PR90 Pulse Rush combines L-Theanine with clean caffeine to deliver 90-second rapid energy with sustained, jitter-free mental focus.
