L-Theanine – Powder, 100 grams

L-Theanine (γ-glutamylethylamide) is a naturally occurring non-protein amino acid investigated for its effects on glutamatergic, GABAergic, and monoaminergic signaling pathways. Experimental studies have demonstrated interactions with glutamate receptor systems, including NMDA and AMPA receptor-associated signaling mechanisms, as well as modulation of glutamate transporter activity. Research has also examined its influence on GABA-related neurotransmission, intracellular signaling cascades, and neurotransmitter regulatory networks. Its well-characterized activity profile makes L-Theanine a valuable research tool for investigations of glutamatergic signaling, receptor pharmacology, neurotransmitter modulation, electrophysiological activity, signal transduction mechanisms, and comparative amino acid neuropharmacology.
