BREIGN® | Focus, Cognitive Performance and Brain Health

ZONED OUT?

Stop reading if your thoughts are always present and distraction not an issue.

If focus is rare and your brain does what it wants, you may continue.

Your mind will wander for 450.2 minutes of your time today.* What if you could access attention without losing control?

You are not slow, nor are you undisciplined.

Distractibility pulls you out of work, too little or too much drive and you can't concentrate at all.

What if people who concentrate aren't gifted, they just found what helps?

The difference? Researchers blame 49% of it on genes*, the rest is mostly exercise, sleep and nutrition.

Focus isn't given, you can start supporting it today.

CALIBRATED BASED ON SCIENCE

Smart Caffeine
Caffeine alone increases wakefulness by strongly stimulating our nervous system. In order to concentrate we have to regulate this stimulus. Combining it with L-theanine has been associated with balanced side effects and improved results in cognitive testing. [1][2][3]
Neuro Activator
EGCG is a polyphenol only found in green tea. Studies indicate that it activates alpha waves in the brain. This is the frequency that initiates a calm but entirely present state of mind. Some researchers explain these power waves as a core driver to improve working memory. [4][5]
Neuro Defense
Polyphenols from green tea and guarana seeds neutralize harmful molecules and activate messenger proteins in controlled studies, initiateing the cell’s own protection protocol. They are thought to support mitochondrial function, for an efficient energy metabolism. [6][7]

I STRUGGLE WITH CONCENTRATION SINCE FIRST GRADE

YOU CAN PROFIT FROM MY OBSESSION TO FIX IT

When I started looking for something that actually worked, I found a hundred products that all said the same three things.

"No crash, no jitters, just energy"

Instead, I believe that focus can be viewed holistically and the majority of us can become 'concentration professionals' by changing just a few habits.

INSPIRED BY NATURE, IMPROVED AND TESTED WITH SCIENCE

Sourced carefully and tested rigorously so you can sleep at night. Literally.

GREEN TEA FROM THE WUYI MOUNTAINS IN FUJIAN

Traditional Chinese medicine has used the plant for over two thousand years. Scientific recalibration builds on that foundation.

THE PLANTS GROW ON VOLCANIC SOIL

The region's mineral-rich ground, high altitude, and harsh weather drive the leaf's high concentration of active ingredients.

EYES OF THE AMAZON

Native to the Brazilian Amazon, the guarana seed delivers more caffeine than a coffee bean, alongside its own polyphenols and theobromine. The locals have used it for centuries. We use the whole seed's extract, not just the caffeine.

WE STAND BEHIND OUR OFFER

Premium extracts from named regions ensure that you get exactly the nutraceuticals you pay for. Every batch is tested against 500 pesticides at SGS Berlin, to an organic-grade level. We test to show our trust in the product, not to brag. If a batch does not meet our standards, it does not ship.

FAQ

Is it an alternative to coffee and energy drinks?

It is more like an upgrade to classic stimulants. Ask yourself how productive the third cup of coffee really is.

Instead of pushing stimulation beyond comfort, KLARIS aims to support focus with smoother, more controlled energy.

Will I still feel caffeine's benefits?

Yes. The goal is not to remove arousal, but to make it more productive and
less tense.

Will it cause jitters or a crash?

The formulation is designed to reduce nervous overstimulation and avoid the sharp rise-and-fall effect commonly associated with coffee or energy drinks. Individual sensitivity may vary, but the general effect is a calm, steady focus.

Who is it designed for?

Finance, surgery, creative work, a difficult afternoon. The cognitive demand is the same regardless of the context.

If concentration feels increasingly hard to sustain, or caffeine is creating more edge than focus, KLARIS might be for you.

Why is it a drink and not a capsule?

Because focus is not just biochemical, but behavioral. A drink creates a pause, followed by a transition into focused work. It avoids the unpleasantness many people associate with green tea's bitterness or swallowing the extract in capsules.

EGCG has a long history of consumption through tea and other beverages. While concentrated extracts are regulated with specific intake recommendations, their use in beverage-based formats is considered to be safe.

How much did your mind wander just reading this page?

We regularly lose entire minutes without a single thought about the task in front of us.

I know the cost of my drifted attention. Let’s begin I’m skeptical. I want to check the science first

Lab Note 001: Green tea's nutraceuticals

February 1, 2026Robert Noffke
Caffeine usually raises alertness, but on its own it can overshoot into jitters, anxiety, or sleep disruption in sensitive people. Pairing it with L-theanine can deliver a calmer, more controllable focus instead of raw stimulation. EGCG is a different lever, discussed mainly as a long-term neuroprotective ingredient. Overall, green tea's benefits are likely to stem from its combination of compounds, not just a single isolated ingredient. More research is needed on the synergistic effects of these substances on cognition.
