1. Introduction to L-Theanine and Alpha-Wave Brain Activity

Understanding L-Theanine

L-Theanine is a non-protein, water-soluble amino acid predominantly found in the leaves of Camellia sinensis, commonly known as green tea. It is the most abundant form of total amino acids in green tea, accounting for about 50% of the total content, and contributes to the unique taste, flavor, and aroma of the beverage [Saeed et al., 2020]. L-Theanine has various biological effects, including antioxidant, growth promoter, immune booster, anti-stressor, hepatoprotective, antitumor, antiaging, antimicrobial, anti-inflammatory, and antianxiety properties [Saeed et al., 2020]. It is also found in some mushrooms and is considered an essential compound for improving immune function [Qui, 2022].

The role of alpha-wave brain activity in focus and productivity

Alpha waves are a type of brainwave activity that occurs when the brain is in a relaxed, yet alert state. They are associated with increased focus, mental clarity, and productivity. When alpha-wave activity is higher, individuals tend to experience reduced stress, enhanced cognitive performance, and better overall mental well-being. In a study conducted during the COVID-19 pandemic, a single dose of AlphaWave® L-Theanine significantly increased frontal region alpha power compared to a placebo in response to an acute stress challenge, indicating relaxation in the brain and suggesting a calming response [Evans et al., 2021].

The connection between L-Theanine and alpha-wave brain activity

L-Theanine has been shown to increase alpha-wave brain activity, leading to improved focus, productivity, and stress relief. In the same study mentioned earlier, AlphaWave® L-Theanine led to a greater increase in frontal region and whole-scalp alpha power 3 hours post-dose compared to a placebo [Evans et al., 2021]. This increase in alpha power was also supported by greater decreases in salivary cortisol, a stress hormone, 1 hour post-dose with AlphaWave® L-Theanine compared to a placebo [Evans et al., 2021]. These findings suggest that L-Theanine may play a significant role in enhancing focus and productivity by promoting alpha-wave brain activity and reducing stress.

2. The Science Behind L-Theanine and Alpha-Wave Brain Activity

Understanding L-Theanine

L-Theanine is a nonprotein water-soluble amino acid found primarily in the leaves of Camellia sinensis, the plant used to produce green tea. It is a key component of green tea and accounts for about 50% of its total amino acids, contributing to the unique taste and aroma of the beverage (Saeed et al., 2020). L-Theanine has been associated with various biological effects, including antioxidant, growth promoter, immune booster, anti-stressor, hepatoprotective, antitumor, antiaging, antimicrobial, anti-inflammatory, and antianxiety activities.
