L-Theanine

L-theanine is an amino acid found naturally in tea, supplied by Nustras as a white crystalline powder for calm-, focus- and sleep-support formulations. It is well studied for promoting relaxation without sedation, and is widely used alone and alongside caffeine for focused calm.

L-theanine is formulated into calm-, focus- and sleep-support supplements, nootropic and stress-relief blends, functional beverages and energy drinks, and gummies, in capsules, tablets and powders.

The material carries CAS 3081-61-6, the molecular formula C7H14N2O3, and is a white crystalline powder, typically supplied at high assay (for example not less than 98%). Identity, assay, specific rotation, heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies L-theanine in bulk commercial quantities, in fibre drums or cartons, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. L-theanine is an accepted dietary ingredient in major supplement markets; buyers confirm the assay, dose and claim for their product. Contact us for assay, pricing per kilogram and lead time.
