KA-EX Cortisol Stress Reducer
You're training harder than ever, but recovery still feels like it's dragging you down. Here's what most athletes miss: it's not just about what you do during workouts—it's about what happens to your cortisol after. When stress hormones stay elevated, your body can't rebuild. Sleep suffers. Energy tanks. Progress stalls.
KA-EX is the world's first clinically-proven cortisol reducer that works in 48 hours.
What Makes It Different
Cortisol Control That Actually Works Clinical studies show a 36% faster return to normal cortisol levels within 48 hours. This isn't about masking fatigue—it's about fixing the root cause of incomplete recovery.
Swiss-Engineered Recovery Stack Phosphatidylserine tells your body to dial down stress hormones. L-tryptophan supports deep REM sleep. L-glutamine and targeted amino acids rebuild what training breaks down. This goes way beyond basic electrolytes.
Zero Stimulants, Maximum Results No caffeine. No taurine. Just clean, functional ingredients that work with your body's natural recovery systems. Vegan, gluten-free, and Informed Sport certified for pro athletes.
Olympic gold medalists and F1 drivers rely on this formula because when cortisol drops, everything else improves—muscle growth, testosterone, immune function, and endurance. If it’s good enough for the world’s best, it’s good enough for your PR goals.
How to Use It
Post-Workout: Mix 1 sachet in 10-17oz cold water immediately after training. For ready-to-drink bottles, push the cap to activate and consume right away.
Next-Day Dose: Take another serving 24 hours later, even on rest days. Cortisol doesn't take days off, so neither should your recovery strategy.
Pro Tip: Daily use delivers the best results—lower baseline cortisol means more energy in everyday life, not just after workouts.
Social Proof
KA-EX is the official supplier to PSG, Tudor Pro Cycling Team, Swiss National Soccer Team, and thousands of Olympic athletes and World Champions. Fabian Cancellara calls it "the perfect complement for top performance." When the world's best trust their recovery to one product, that tells you everything.
Gluten-free, dairy-free, vegan, vegetarian, tree-nut & peanut-free, soy-free, and stimulant-free. This isn't just another recovery drink. This is Swiss science solving the problem most athletes don't even know they have.
