Product Introduction

Products Description

Theanine Powder is a naturally occurring amino acid extracted from tea leaves (Camellia sinensis), known for its calming effects. Derived from green and black teas, it promotes relaxation without drowsiness by modulating neurotransmitters like dopamine and serotonin. Joywin Natural's Theanine delivers 99% pure L-Theanine – the bioactive isomer clinically proven to reduce stress, enhance focus, and improve sleep quality without drowsiness. Sourced from premium green tea (Camellia sinensis) and produced via enzymatic fermentation, our pharmaceutical-grade powder offers unparalleled purity and consistency.

As a supplement, it supports cognitive health, reduces stress, and improves sleep quality. Commonly used in nootropics or beverages, it offers a natural way to balance mental well-being by inducing alpha brain waves linked to wakeful relaxation. Safe and mild, it's favored for its adaptogenic properties and minimal side effects.
