See all ingredientsYour second half of the day consistently underperforms the first. Slower decisions, reduced concentration, mentally checked out by 3pm. CLEAR is designed specifically for this window, extending afternoon output without relying on more caffeine.
You carry background stress that quietly degrades your focus and physical recovery. CLEAR works at the cortisol level, supporting both cognitive clarity and the adaptogenic recovery that athletes and high performers need.
Bright and citrus, made with real lemon juice and lemon essential oil.
One 30ml shot, straight from the bottle, with or without food. We recommend the afternoon, for clear thinking through the second half of the day. There is no caffeine in it, so it works whenever you need it.

Strategic enhancement for high-stakes moments
The shifts you feel, and the actives behind each one.
Improves Memory & Recall
+63%
In clinical research, participants showed a 63% improvement in memory performance. Alpha GPC raises acetylcholine, the brain's memory messenger, while Ginkgo Biloba and Acetyl-L-Carnitine keep neurons supplied with oxygen and energy.
Reduces Mental Fatigue
+30%
In a placebo-controlled trial, participants taking Acetyl-L-Carnitine showed a 30% improvement in fatigue resistance. Vitamin B12 and N-Acetyl Cysteine support the same energy pathway at the cellular level.
Improves Mental Clarity
+57%
Clinical research on Ginkgo Biloba shows a 57% increase in cerebral blood flow. More blood flow means more oxygen and glucose reaching neurons. Vitamin C and Glutathione protect those neurons while they work harder.

What you'll feel, and when
Enhance focus, energy, and clarity, one sip at a time.
First 15 Mins
Most people experience the fog starting to lift within minutes of the first shot.
Next 4-8 Hours
Thinking stays quick and clear as Alpha GPC raises acetylcholine and ginkgo lifts cerebral circulation. A calm, clear-headed state that lasts.
No Crash Ever
No stimulants are doing the lifting, so there is nothing to crash from. Just clean, clear function.
Week 1
You'll notice more clarity in the mornings and the fog staying gone for longer, as antioxidant capacity builds day on day. Brain fog is a thing of the past.
Week 2+
Your cognitive stamina improves as glutathione stores rise and mental fatigue drops 35% in trials. Clarity becomes your norm, not a boost.

There's only one way to know
I think it's pretty easy to be sceptical of a product that says it can boost your brain in a shot. But the only way to test that scepticism was to try it for myself. And in all honesty, I'm glad I did...

Frequently asked questions
CONKA Clear is best taken 30-60 minutes before you need peak performance, such as important meetings, competitions, or creative work. It's also effective in the afternoon for recovery.
CONKA Flow focuses on daily energy and stress resilience with adaptogens. CONKA Clear is designed for peak mental performance with nootropics that enhance clarity, reaction time, and decision-making.
Yes, CONKA Clear can be taken daily. Many users pair it with CONKA Flow as part of a protocol for comprehensive cognitive support.
Yes, CONKA Clear is specifically formulated to eliminate brain fog through enhanced blood flow to the brain and improved neurotransmission in the frontal cortex.
For most people, no, and CONKA is generally well tolerated. The most commonly reported effect with botanical supplements like these is mild digestive change in the first few days as your body adjusts. Because both formulas are caffeine-free, there are none of the jitters, spikes or crashes a stimulant causes. If you have an unusual or persistent reaction, stop taking it and speak to your doctor.
It depends entirely on the ingredient and the dose, and most of the category deserves its scepticism. Plenty of nootropics are proprietary blends in a capsule, where the ingredient is named but the amount is a fraction of what the research used, so the study the label leans on does not apply to the product in your hand. What we did instead was build the formulas around the doses used in published trials, put them in liquid so they are absorbed rather than sitting in a capsule shell, and then measure the result: the CONKA app runs a two-minute cognitive test so you can see your own scores rather than trusting ours.
