KA-EX is a Swiss-developed recovery supplement positioning itself as a cortisol stress reducer.

The product was founded in 2017 by Pedro Schmidt, a graduate of the pharmaceutical sciences program at ETH Zurich.

Originally developed for hangover recovery — the name comes from the German "Kater" (hangover) and the Latin "Ex" (out) — before pivoting to sports nutrition after consumers started using it for exercise recovery.

Informed Sport certified, vegan, caffeine-free.
