Mental performance
Calm morning focus and sharp afternoon recall.
Lemon Balm
Calms anxiety without sedation. 28% drop in stress response.
Reduces anxiety and sharpens calm focus by inhibiting GABA-transaminase — no sedation, no next-day grogginess. Rosmarinic acid adds antioxidant protection for the neurons doing the work.
Studies support
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 supportSustained energy
Steady energy across the full cognitive day.
Rhodiola rosea
Fights burnout and mental fatigue under prolonged stress.
Fights burnout and preserves mental performance under prolonged stress — 28% drop in burnout score after 28 days. Rosavins and salidroside protect dopamine and serotonin so energy holds when the pressure doesn't stop.
Studies support
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
Neuroprotection and antioxidant defense, morning to evening.
Turmeric
Protects neurons and improves memory by 63% over 18 months.
Curcumin crosses the blood-brain barrier to calm neuroinflammation and raise BDNF, the signal the brain needs to form new connections. In an 18-month UCLA trial, memory improved 63% and attention 96% against placebo.
Studies supportGlutathione
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
Bilberry
Anthocyanins cross the blood-brain barrier to improve recall 18%.
Anthocyanins cross the blood-brain barrier and improve word recall by 18% in older adults. Also protects microcirculation and retinal function — the same blood flow cognition depends on.
Studies supportWho is it for?
You need 10+ hours of consistent cognitive performance. FLOW in the morning for sharpness and energy. CLEAR after lunch for afternoon precision and focus. Together they cover the full day without stimulant cycling or a mid-afternoon drop.
You're optimising cognitive and physical performance across a full day, and want to reduce caffeine dependence without reducing output. A timed, sequenced system achieves more than either formula alone.
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.

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
Most nootropics are capsules with underdosed ingredients. CONKA is a liquid shot: clinical doses in 30ml, absorbed fast. It's a complete system, Flow for your morning, Clear for your afternoon. The formula is patented (GB2620279). Every batch is Informed Sport tested. And you don't have to take our word for any of it: the CONKA app tracks your cognitive scores, so you can measure the difference yourself.
Yes. CONKA is built for daily use, and every batch is Informed Sport certified and tested for 280+ banned substances, the same standard professional athletes are held to. Both formulas are caffeine-free, so there is no stimulant to build up. If you are pregnant, breastfeeding, giving it to a child, or taking prescription medication, read the questions below and check with your doctor before starting.
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.
Day 1: sharper focus and steady energy, no crash. Day 14: adaptogens like Ashwagandha reach full strength and stress rolls off faster. Day 30: your baseline sits measurably higher. Across 150+ tested users and 5,000+ cognitive tests, the average score improvement was +28.96%.
Two shots, ten seconds each. Flow in the morning to set up your focus for the day. Clear in the afternoon, right when most people hit the dip. Straight from the bottle. No powders, no mixing, no timing windows.
Flow (black cap) is for mornings: adaptogens like Ashwagandha and Lemon Balm for calm, caffeine-free focus. Clear (white cap) is for afternoons: nootropics like Alpha GPC and Glutathione, plus Vitamin C. Both is the full system. Morning to evening covered, designed to work as a pair, and the best value per shot.
Then you get your money back. Try CONKA for up to 100 days, and if you're not satisfied, contact us for a full refund. No returns needed, no questions asked. That's the 100-day money-back guarantee: we're confident enough in the product to take the risk for you.
