Your questions - Our answers

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.

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.

Yes — KA‑EX® is 100% vegan, gluten-free, and lactose-free.

Mix one sachet with 500 ml (approx. 17 oz) of cold water. Shake well until fully dissolved. For best results, drink chilled.
KA‑EX® is designed to be taken after physical exercise or activity to support recovery. Since recovery processes last over 48 hours, many athletes also take it on rest days. It can also be helpful after mentally or physically stressful days.

Yes! KA‑EX® can be taken on demanding workdays, during mental fatigue, or whenever your body is under stress — physical or psychological.

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.

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.

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.

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.

Currently, KA‑EX® is only available in its original formulation and citrus flavor.

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.

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.

The recommended serving is one KA‑EX® (sachet or bottle) per day.
