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.
