Our Story · Founders
Est. 2020 · Two founders · One mission
After a trip to the Olympics and a career-ending concussion, two athletes set out to solve a problem nobody was talking about: recovery for the brain. CONKA is the result — two formulas, years of research, and a belief that your brain deserves better than caffeine and hope.

Response
CONKA Flow (black cap) is your morning foundation. It uses adaptogens like Ashwagandha and Lemon Balm for calm focus without caffeine. CONKA Clear (white cap) is your afternoon recovery shot. It combines nootropics like Alpha GPC and Glutathione with Vitamin C, which contributes to normal psychological function.†† One of each, every day.
Response
Yes. You can subscribe to Flow or Clear individually. However, the two formulas are designed to work as a daily pair. Flow supports your daytime focus and energy, Clear supports your afternoon recovery. Together they cover the full 24-hour cycle, and the combined subscription is better value per shot.
Response
Orders placed before 2pm ship same day. Most UK customers receive their order within 1 to 2 working days. Subscriptions ship free. You’ll receive tracking information by email as soon as your order dispatches.
Response
Cancel, pause, or modify anytime from your account. No contracts, no commitments, no questions asked. We also offer a 100-day money-back guarantee, so if you're not satisfied, you get a full refund.
