Capacity left for the evenings

I take something after work, lock back in for the hustle, and still sleep well. Sharper on client work during the day.

Measure it to manage it

What can't be measured can't be managed. I have more energy, and if you're pessimistic, just do a before and after test.

Motivation02

Motivation Comes From a Fuelled Mind

After a heavy week or a short night, your brain has less to give. The hardest part of any task is the first minute, and it takes the most energy. Flow before opening your laptop prepares you for the day ahead.

Memory03

Feeling Slow? Your Brain Is Just Overloaded.

Words get lost mid-conversation. Names go blank. It's normal to fear the worst, but most days your head is simply carrying more than it can handle. A ten-year study of over 7,000 people found the slip in processing speed already measurable by 45. CONKA Clear supports the moments that count.

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.

Earthy and slightly sweet, led by turmeric. It pours as a yellowish-brown liquid.

One 30ml shot, straight from the bottle, with or without food. We recommend the morning, for calm focus and jitter-free energy through the day. There is no caffeine in it, so it works whenever you need it.

Frequently asked questions

No. Both CONKA Flow and CONKA Clear are completely caffeine-free. There is no stimulant in either formula, which means nothing to spike from and nothing to crash off, and it is why Clear can be taken in the afternoon without the sleep problem an afternoon coffee causes.

An energy drink spikes you on caffeine and sugar and then drops you; CONKA does neither. Both CONKA formulas are caffeine-free, so there is no stimulant to spike from and nothing to crash off. Instead of a short hit, the two daily shots are built around adaptogens and nootropics dosed to the levels used in published trials, aimed at steady focus across the whole day. It is a daily supplement you take to hold a level, not a drink you reach for once you are already flagging.

The NHS suggests keeping caffeine to around 3mg per kg of body weight, so roughly 225mg a day for a 75kg adult, about two cups of coffee or one energy drink. Above that, common side effects include disrupted sleep, anxiety and raised blood pressure. Cutting back can bring short-term withdrawal for a few days, usually headaches or fatigue, which is one reason people look for a steadier alternative rather than stopping cold. Because both CONKA formulas are caffeine-free, they give you a way to hold your focus while you ease off the cups, without adding another stimulant to crash from.

CONKA Flow in the morning, CONKA Clear in the early afternoon. Flow is designed to set up the front half of your day and can be taken with or without food. Clear is designed for the point most people hit the dip and reach for a second coffee, so early afternoon is the natural slot, though it also works 30 to 60 minutes before something demanding. Neither has a strict timing window; consistency matters more than the exact hour.

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 is caffeine-free, so it works alongside your morning coffee rather than competing with it, and there is no interaction to worry about. What is interesting is our own app data: measured against people's own baselines, coffee on its own barely moved their cognitive scores, while the measurable gains tracked with CONKA. Among users who logged both, adding CONKA on top of their coffee was associated with higher scores and fewer errors. Most people also find they reach for fewer cups over time, but nothing about CONKA requires you to give up coffee.

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.
