CATEGORY

Theanine—chemically known as N-ethyl-γ-L-glutamine—is a unique free, non-protein amino acid found specifically in tea leaves. It was first isolated and identified in 1950 by the Japanese scientist Yaijiro Sakato from Gyokuro tea. Theanine constitutes approximately 1% to 2% of the dry weight of tea leaves; it is the most abundant free amino acid in tea, accounting for roughly 50% to 60% of the total free amino acid content. Not only is it the primary source of the fresh, crisp flavor of brewed tea—imparting a caramel-like aroma and an umami taste reminiscent of MSG—but it also possesses a variety of significant physiological regulatory functions.

Function

In the functional beverage sector, L-theanine is frequently incorporated into sports drinks, energy drinks, and sleep-aid beverages to promote alertness, combat fatigue, or improve sleep quality. For instance, certain sports drinks leverage the synergistic effects of L-theanine and caffeine to help athletes maintain focus while remaining in a relaxed state.

In the field of daily chemical products, L-theanine is added to skincare formulations—such as anti-aging creams—to capitalize on its antioxidant properties and skin-rejuvenating effects.

Within the pharmaceutical and health supplement sectors, L-theanine is utilized in the development of dietary supplements designed to enhance memory, alleviate stress, boost immunity, and provide supportive care in anti-tumor therapies.

Furthermore, L-theanine is employed in the production of insect health supplements to protect pollinating insects from pesticide toxicity, as well as serving as a feed additive to improve meat quality in livestock and enhance their resilience to heat stress.
