Mental performance
Sharper focus, calm attention, and 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
Ashwagandha
Cuts cortisol 28% and perceived stress by more than half.
Lowers serum cortisol 28% and perceived stress by more than half via HPA-axis modulation by withanolides. Sleep quality climbs in parallel — stress and recovery handled together.
Studies supportSustained energy
Steady mental energy and stress resilience, without the crash.
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 supportBrain health
Protects neurons and supports long-term cognition.
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.
Paired with Black Pepper: Multiplies curcumin absorption 2,000% so the rest of the formula works.
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 want sustained energy and sharp focus across a full cognitive day, without the crash. FLOW stacks alongside your coffee to extend its effect and reduce how much you need, or replaces it entirely through cellular energy production rather than stimulant dependency.
Your work demands hours of clean output: deep focus, back-to-back calls, physical training. FLOW supports both cognitive and physical performance through the same mitochondrial pathways.

Improves Memory & Recall
+18%
In a placebo-controlled trial, participants taking Lemon Balm showed an 18% improvement in memory performance. Bilberry and Rhodiola support the same outcome through cerebral circulation and stress resilience.
Reduces Tiredness & Fatigue
Reduces
Ashwagandha and Rhodiola are adaptogens: they help your body handle demanding days rather than masking the fatigue. Turmeric keeps inflammation in check, and the formula's vitamin content carries an EFSA-authorised claim for reducing tiredness and fatigue.
Improves Sleep Quality
+42%
In an 8-week clinical study, participants taking Ashwagandha reported a 42% improvement in sleep quality. Lemon Balm adds calm without sedation, so the wind-down starts before your head hits the pillow.
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.

Absorbed, not wasted
Our liquid formula gets active ingredients into your system, so your brain gets more of what it needs.
Maximum bioavailability
Liquid skips the slow breakdown a tablet needs, so more of each compound is ready for your body to absorb.
Fast absorption
A liquid is ready to absorb in minutes, not the hours a pill spends dissolving first.
Proven dosages
Every compound is dosed at the levels used in real research, not sprinkled in for the label.

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 Flow is best taken in the morning with or without food. It's designed as a coffee replacement that provides sustained energy without caffeine.
No. CONKA Flow is completely caffeine-free and actually helps improve sleep quality by +42% according to a peer-reviewed study on Ashwagandha (PMID: 32021735).
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%.
Yes. CONKA Flow is caffeine-free, so it works alongside your morning coffee rather than competing with it. Most people find they reach for fewer cups once the adaptogens are giving them steady energy without the crash.
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.
