L-Theanine – Direct-Compression Grade

L-Theanine is a non-proteinogenic amino acid naturally found in tea leaves, now produced by enzymatic or fermentation routes as well as tea extraction. It is valued for promoting relaxation without drowsiness and pairs well with caffeine for smooth focus; liposomal, microencapsulated and application grades broaden formulation options.

Direct-compression grade engineered for flow and compressibility, suitable for tablet manufacture without wet granulation.
