Mar. 16, 2026

1. Introduction to L-Theanine and GABA

L-Theanine, a prominent amino acid found in tea leaves, is favored for its anxiety-reducing effects, while GABA (gamma-aminobutyric acid) is a significant neurotransmitter that promotes relaxation. Both compounds are widely used in dietary supplements targeting mental health and cognitive enhancement.
