Your questions - Our answers
What does KA-EX® taste like?
KA‑EX® has a light, refreshing citrus flavor with a clean finish. The slightly salty note comes from its natural electrolyte content — it’s not overly sweet or artificially flavored.
Does KA‑EX® have any side effects?
KA‑EX® is generally well tolerated, and no side effects have been reported after millions of servings sold in Switzerland. People with sensitivities to certain vitamins or minerals should still assess individual tolerance. If you have known intolerances or medical conditions, we recommend consulting a healthcare professional before use.
Is KA‑EX® vegan, gluten-free, and lactose-free?
Yes — KA‑EX® is 100% vegan, gluten-free, and lactose-free.
How do I mix KA‑EX®?
When should I take KA‑EX®?
Can I take KA‑EX® even if I’m not working out?
Yes! KA‑EX® can be taken on demanding workdays, during mental fatigue, or whenever your body is under stress — physical or psychological.
Is KA‑EX® clinically tested?
Yes! KA‑EX® can be taken on demanding workdays, during mental fatigue, or whenever your body is under stress — physical or psychological.
Can diabetics take KA‑EX®?
KA‑EX® contains 6 g of glucose and 12 g of fructose per serving — similar to the sugar content of an average apple. Diabetics should account for this in their insulin or dietary management and consult with a healthcare provider if unsure.
Can KA‑EX® be taken during pregnancy or breastfeeding?
There are no known concerns, but KA‑EX® contains several vitamins (e.g. folate, B12, C) that might already be supplemented elsewhere. It’s important not to exceed daily recommended intake. Please consult a doctor before use during pregnancy or breastfeeding.
What’s the minimum age for taking KA‑EX®?
KA‑EX® is recommended for individuals aged 13 and older. Younger individuals have different nutritional needs, and supplementation should only be done under professional guidance.
Does KA‑EX® contain caffeine or stimulants?
No. KA‑EX® is 100% free from stimulants like caffeine or taurine. Instead, it contains natural ingredients that support recovery, sleep, and overall well-being without disrupting cortisol or sleep cycles.
Is there more than one flavor or version of KA‑EX®?
Currently, KA‑EX® is only available in its original formulation and citrus flavor.
How is KA‑EX® different from a regular sports drink or electrolyte mix?
KA‑EX® is clinically developed and patented in Switzerland. It goes far beyond basic electrolytes by including cortisol-lowering bioactives (like phosphatidylserine), amino acids (like L-tryptophan for sleep), antioxidants (like L-cysteine), and functional sugars to restore glycogen. It’s a full-spectrum recovery solution.
Are the powder sachets and the push-cap bottles the same formula?
Yes — both formats contain the same functional ingredients in the same dosage. The only difference is in the separation of certain components for stability in the bottle.
How often can I take KA‑EX®?
The recommended serving is one KA‑EX® (sachet or bottle) per day.
