See all ingredientsYou 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.
Two shots a day.

For me it was about trying to find the small margins and trying to maximise my brain as well as my body was so important.

Informed Sport tested for over 280 banned substances.
Try CONKA for 100 days. If your mental performance doesn't noticeably improve, we'll refund your purchase completely, no return necessary.

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.

Morning to evening covered, designed to work as a pair, and the best value per shot.
