Studies shows that 200 mg of L-theanine decrease anxiety symptoms and boost sleep quality by generating feel-good neurochemicals, such as dopamine, serotonin, and GABA.

Green Tea's "Calm Alertness

Green tea produces an exceptional blend of L-theanine and caffeine. The research clearly reveals this combination enhance alpha-wave brain activity that led to a state of "calm alert" instead of the jittery energy commonly related to the coffee.

The "CE/TA" Ratio Rule

In 2024, study in Scientific Reports indicated that that green tea's stress-relieving properties are subject to the ratio of "relaxing" compounds (Theanine + Arginine) to "countering" compounds (Caffeine + EGCG). Shaded green teas including Matcha commonly contain lower ratios and are very worthy in reducing stress.

Usual Consumption Effects

In these Studies Japanese, adults have been involved highlighted that that consuming more than 5 cups of green tea daily was linked to lesser levels of psychological distress.
