Mental performance
Sharper recall and clear thinking under pressure.
Alpha GPC
The most bioavailable choline form. Raises acetylcholine for sharper recall.
Raises acetylcholine — the neurotransmitter recall and reaction speed run on — by delivering choline straight past the blood-brain barrier. The most bioavailable choline form in supplementation.
Studies support
Ginkgo Biloba
Improves cerebral circulation. 16% gain in cognition and attention.
Improves cerebral microcirculation so oxygen and glucose reach neurons efficiently. Meta-analyses across 2,372 participants show a 16% gain in cognition and 14% in attention.
Studies support
Lecithin
Phosphatidylcholine rebuilds neuronal membranes and feeds acetylcholine synthesis.
Supplies phosphatidylcholine — the phospholipid that keeps neuronal membranes fluid and feeds acetylcholine synthesis. Higher choline intake tracks with better verbal and visual memory.
Studies supportSustained energy
Cellular energy to carry the afternoon.
Acetyl-L-Carnitine
Fuels neurons with fatty-acid energy. 35% less mental fatigue.
Fuels neurons by moving fatty acids into mitochondria and donates acetyl groups for acetylcholine synthesis. Mental fatigue dropped 35% and cognitive function rose 24% in controlled trials.
Studies support
Vitamin B12
Methylcobalamin slows brain atrophy by up to 86% in trials.
Methylcobalamin is the bioactive form neurons use directly — essential for myelin synthesis and neurotransmitter production. Oxford trials slowed brain atrophy by up to 86% in at-risk adults.
Studies supportBrain health
Antioxidant defense that clears the fog.
Glutathione
The body's master antioxidant. 40% rise in blood stores.
The body's master antioxidant — directly neutralises reactive oxygen species and regenerates vitamins C and E. Oral supplementation raises blood stores 40% in four weeks.
Studies support
N-Acetyl Cysteine
Replenishes cysteine to rebuild glutathione and calm brain glutamate.
Replenishes cysteine, the rate-limiting substrate the body needs to rebuild glutathione. Also modulates brain glutamate, with cognitive improvements measured at 22% in randomised trials.
Studies support
Vitamin C
Neuroprotective antioxidant concentrated 15x in the brain vs plasma.
Cofactor for dopamine and norepinephrine synthesis and the brain's primary water-soluble antioxidant. Concentrated 15x higher in neurons than in plasma — attention gains track with plasma levels.
Studies support
Alpha Lipoic Acid
Universal antioxidant that regenerates vitamin C, E, and glutathione.
A universal antioxidant that works in both water and fat environments and regenerates glutathione, vitamin C, and vitamin E. Also chelates heavy metals and supports mitochondrial energy production.
Studies supportWho is it for?
Your 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.
Try risk free
Try CONKA for 100 days. If your mental performance doesn't noticeably improve, we'll refund your purchase completely, no return necessary.

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.
Clinically-backed ingredients
We source the highest-quality compounds, at proven doses and in bioavailable forms. Each ingredient is supported by independent, peer-reviewed studies.

Caffeine doesn't give you energy.
It borrows it.
Caffeine blocks the receptors that tell your brain it's tired. It hides the fatigue for a few hours, spikes cortisol, and hands both back to you at 11am. The second cup isn't a habit. It's the system working as designed.
Focus levels through the day
Costs £37 less than your monthly coffee bill
CONKA works the other way. Fifteen nootropics and adaptogens do the heavy lifting: brain-boosting nutrients build the focus, stress-mitigating compounds keep cortisol in check. Energy that doesn't have to be paid back.

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.
