Science

Gyokuro is one of the richest natural sources of L-theanine, an amino acid that promotes calm focus, mental clarity, and stress resilience. Shading the tea leaves before harvest increases both L-theanine and antioxidant polyphenols like catechins and EGCG — compounds shown to support cognitive health and heart function. Combined with natural caffeine, Gyokuro boosts alpha brain waves and dopamine activity — enhancing attention, mood, and sustained mental performance without the crash or jitters of coffee.

How to take

Enjoy Hot. Pour 250 ml of 70°C water over 1-2 teaspoons and let it infuse for 1-2 minutes. You can rebrew it up to 4 times.

The Path to Deep Focus

„So many times I sat at my desk and just couldn’t concentrate. I wanted to write, plan a strategy, or come up with something new, but my mind kept drifting in every direction. Time slipped away, tasks piled up, and I felt like I hadn’t accomplished anything meaningful. Today I know that the ability to focus is the key to achieving big things.

But back then, I didn’t have it. I tried coffee and energy drinks to “get going.” Instead of focus, they gave me overstimulation. My body was on high alert, my heart was racing, nervousness grew, and stress piled up. That’s not the state where great ideas are born.

I started searching for a solution that would be healthy, natural for the body, and help me reach a state of calm, clear concentration. That’s when I discovered Gyokuro, one of the rarest green teas in the world. A tea shaded for weeks before harvest to preserve maximum nutrients, and because of that, it has the highest content of L-theanine — a compound that scientists say promotes a state of calm focus.

The first time I tried it, I felt the difference immediately. No nervousness, no overstimulation. Just pure, steady focus. My mind was clear, my thoughts aligned, and my body felt at ease. Since then, Gyokuro has been my ritual whenever I need to create, plan, or step on stage to speak in front of people.

That’s how Dakys Gyokuro was born. We source it directly from a Japanese farmer who is renowned in his region for producing world-class Gyokuro. It’s a pure and natural way to take control of your attention and use it for what truly matters.“

Key Ingredients

L-theanine

L-theanine is a naturally occurring amino acid found almost exclusively in green tea, with the highest levels in shade-grown varieties like Gyokuro. It has been shown to increase alpha brain wave activity, which correlates with a calm yet alert mental state. L-theanine also modulates levels of dopamine and serotonin, contributing to improved mood, reduced stress, and better cognitive performance under pressure. [Nobre et al., 2008 – Cognitive performance and EEG study. Gomez-Ramirez et al., 2007 – L-theanine and sustained attention]

EGCG

EGCG is the most abundant and bioactive polyphenol in green tea. It acts as a powerful antioxidant, helping protect neurons from oxidative stress and supporting overall brain health. Research also links EGCG to improved vascular function, which enhances cerebral blood flow — essential for optimal focus and mental stamina. [Schroeder et al., 2016 – Neuroprotective effects of EGCG. Kim et al., 2014 – EGCG and endothelial function]

Catechins

Catechins, a group of flavonoids found in green tea, including EGCG, EGC, and ECG, exhibit strong anti-inflammatory and neuroprotective effects. They help reduce mental fatigue and support long-term cognitive health by modulating oxidative pathways and neurotransmitter activity. [Kuriyama et al., 2006 – Green tea consumption and cognitive function. Mandel et al., 2006 – Neuroprotective catechins and brain aging]
