Natural amino acid derived from green tea. Increases alpha-wave brain activity — the neural state associated with calm alertness and relaxed focus — without sedation, grogginess, or pharmacologic mechanisms. Supports the excitatory/inhibitory neurotransmitter balance required for sleep onset, promotes parasympathetic tone, and reduces the stress-related racing thoughts that prevent sleep. No dependency, no receptor downregulation, no next-day cognitive impairment.
