Our Story

Built from a brain injury. Backed by £500,000 of research.

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.
