Recent studies indicate that a Swiss functional beverage launching in the US enhances sleep quality, aids in recovery, and mitigates hangover symptoms.


Summary: PRUVN Research LLC, a wellness product validation company, announced findings from three studies on KA-EX, a functional beverage from Switzerland, that demonstrated KA-EX’s effectiveness in enhancing recovery metrics, including heart rate variability, resting heart rate, and sleep quality among physically active participants, as well as reducing hangover symptoms. KA-EX is launching in the US.

Key Takeaways:

  • A pilot trial incorporating wearable technology and participant-reported outcomes found that KA-EX significantly improved recovery metrics such as heart rate variability (HRV), resting heart rate, and overall sleep quality among physically active participants.
  • A second study showed that KA-EX eased several symptoms of alcohol-induced hangovers, including a 35% reduction in dehydration and a 32% reduction in headaches.
  • A third study with the Swiss National Football Team revealed a 36% decrease in cortisol levels within 48 hours post-workout, emphasizing the beverage’s role in reducing stress and improving sleep.

PRUVN Research LLC announced the results of three studies that highlight the potential of KA-EX, a Switzerland-based functional beverage, to improve sleep, recovery, and hangover symptoms as it enters the US market.

The pilot trial, which incorporated wearable technology and participant-reported outcomes, found the beverage improved recovery metrics such as heart rate variability (HRV), resting heart rate, and overall sleep quality among physically active participants. 

Plus, an additional study investigating its impact on alcohol consumption showed it eased several symptoms of alcohol-induced hangover.

Scientific Insights on KA-EX Highlight Improved Sleep

Francisco Cidral, chief scientific officer and co-founder of PRUVN, emphasized the importance of these findings, stating that “from a scientific perspective, the improvements we’ve observed, including increased deep sleep and heart rate variability, as well as decreased resting heart rate, are crucial for overall health.” 

Cidral adds in a release, “Deep sleep is vital for physical recovery and immune function, whereas resting heart rate and HRV are one of the main biometrics used to quantify physiological stress response and resilience. For consumers, this means that a product improving their daytime state can extend its benefits into the night, promoting better sleep quality, which is foundational for both physical and mental health.”

Clinical Results

The second study, a general wellness study, utilized a dual approach incorporating objective biometric data from wearable devices alongside subjective feedback from participant surveys. Findings revealed a 10% reduction in stress based on biometric changes (including improved heart rate variability) and a 6% increase in deep sleep. Plus, participants reported less perceived stress and fatigue. Also, notable was a 4% decrease in resting heart rate with no major lifestyle changes.

In a third, separate study that KA-EX conducted independently with the Swiss National Football Team, the use of its beverage led to a statistically significant 36% decrease in cortisol levels within 48 hours of post-workout. This stress hormone affects muscle growth, sleep, immune system functionality, and overall health.

Ingredient Profile

KA-EX curated several ingredients in its beverage from amino acids and electrolytes to micronutrients and bioactive compounds, such as phosphatidylserine and betaine, to target multiple biological processes involved in sleep, stress reduction, and recovery. 

“While many ingredients may be beneficial on their own, they might compete for the same cellular pathways or even cancel each other out when combined. Maybe the dosage is not high enough, the ingredient is not in a bioavailable form, or it doesn’t survive in the gut environment the way it needs to. So, in the end, what you need to do with any formulation is prove it clinically, which is what KA-EX has done,” says Elias Arjan, CEO and co-founder of PRUVN, in a release.

KA-EX is launching exclusively at Earthbar in California and will be available on Amazon and the company’s website. These statements have not been evaluated by the US Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
