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.

CONKA Flow is earthy and slightly sweet, led by turmeric, and pours as a yellowish-brown liquid. CONKA Clear is bright and citrus, made with real lemon juice and lemon essential oil.

One 30ml shot, straight from the bottle, with or without food. Flow in the morning for calm focus and jitter-free energy. Clear in the afternoon for clear thinking through the second half of the day. Neither contains caffeine, so you can take them whenever you need them.

What you'll feel, and when

Enhance focus, energy, and clarity, one sip at a time.

  1. First 15 Mins

    Most people experience a mental uplift within minutes.

  2. Next 4-8 Hours

    A heightened flow state from the synergistic effects of both formulas. Experience a calm, focused, long-lasting productive state of mind.

  3. No Crash Ever

    Plant-based energy and stress-busting adaptogens create a steady, energised state without a crash.

  4. Week 1

    You'll notice increases in productivity due to less fatigue in the afternoons and more clarity in the mornings. Brain fog is a thing of the past.

  5. Week 2+

    Your cognitive stamina improves as nootropics boost acetylcholine and neurogenesis, while adaptogens enhance your mood by regulating cortisol and stress.

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

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%.

One 30ml shot, straight from the bottle, with or without food. Flow in the morning for calm focus and jitter-free energy. Clear in the afternoon for clear thinking through the second half of the day. Neither contains caffeine, so you can take them whenever you need them.

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.
