• Reduces physical and mental fatigue

Folate, magnesium, niacin, pantothenic acid, riboflavin, and vitamins B6, B12, and C contribute to the reduction of tiredness and fatigue. Pantothenic acid supports normal mental pertormance, while zinc contributes to normal cognitive function.

• Supports muscle recovery and protein synthesis

Calcium, potassium, and magnesium contribute to normal muscle function. Magnesium and zinc contribute to normal protein synthesis.


• Supports digestive enzyme activity and acid-base balance

Calcium contributes to the normal function of digestive enzymes, while zinc contributes to normal acid-base metabolism.

• Supports liver function and metabolism

Choline contributes to the maintenance of normal liver function. Folate and vitamins B6 and B12 contribute to normal homocysteine metabolism.

• Protects cells from oxidative stress

Riboflavin, selenium, vitamin C, vitamin E, and zinc help protect cells from oxidative stress.

• Supports healthy skin, hair, and nails

Niacin, riboflavin, and zinc contribute to the maintenance of normal skin. Vitamin C contributes to normal collagen formation for normal skin function. Selenium and zinc contribute to the maintenance of normal hair and nails.

• Supports normal heart function

Thiamine contributes to normal heart function.

1. When and how should I take KA-EX® RECHARGE+? 
KA‑EX® is designed to be taken immediately after physical exercise or activity to support recovery. The cortisol spike from exercise peaks within 30-90 minutes post-training, making the post-workout window critical. Since recovery processes last over 48 hours, many athletes also take it on rest days.

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

The recommended serving is one KA‑EX® per day, available in either sachet or bottle format. Mix one sachet with 500 ml (approx. 17 oz) of cold water, shake well until fully dissolved, and drink chilled. 
 
2. Can diabetics take KA-EX® RECHARGE+? 
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 professional if unsure. 

3. Can pregnant or breastfeeding women take KA-EX® RECHARGE+? 
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 the recommended daily intake. Please consult a doctor before using during pregnancy or breastfeeding. 

4. Does KA-EX® RECHARGE+ contain caffeine or stimulants? 
No. KA‑EX® is 100% free from stimulants like caffeine or taurine.

5. Why does KA-EX® RECHARGE+ contain sugar? 
It’s true that sugar can cause a short-term cortisol spike lasting 30 to 60 minutes. However, in the context of post-exercise recovery, this effect is largely irrelevant.  

Intense physical activity elevates cortisol levels for 48 to 72 hours due to muscle damage, inflammation, and systemic stress. In comparison, the brief spike caused by sugar is minimal and does not contribute to any meaningful additional cortisol load. 
 
KA‑EX® contains only 18g of sugar—the same amount and type found in a regular apple (12g fructose, 6g glucose)—and is classified as “low in sugar.” Yet this small amount plays a critical role in the product’s effectiveness by enabling key recovery processes:  

• Replenishment of muscle glycogen: Glycogen is the body’s primary fuel source during exercise. Recovery requires energy, and restoring glycogen immediately post-workout is essential for proper muscle repair and performance rebound. 
 
• Facilitated nutrient and electrolyte absorption: Sugar acts as a transport facilitator. As glucose and fructose are taken up into muscle cells, they carry along vital co-transported substances—such as electrolytes, L-glutamine (for cellular repair), anti-inflammatory compounds, and alkaline minerals to restore optimal pH balance.  

Research shows that even when the body is adequately supplied with protein and other nutrients, the absence of sugar post-exercise can reduce recovery efficacy by up to 34%. In fact, after high-intensity training, it is often recommended to consume 60g of carbohydrates to support full recovery. 

6. How is KA-EX® RECHARGE+ different from a regular sports drink or electrolyte mix? 
Most sports drinks and electrolyte mixes are designed with a single goal in mind: rehydration. They typically contain water, sodium, potassium, and simple carbohydrates to replace what is lost through sweat during exercise. While these are important, they address only one dimension of what your body needs after intense physical activity. 

KA‑EX® is clinically developed and patented in Switzerland as a full-spectrum recovery formula, targeting multiple recovery pathways simultaneously: 

• Hormonal recovery: Phosphatidylserine supports regulation of the cortisol response to exercise-induced stress, helping the body return to hormonal balance more efficiently. 

• Muscle repair and immune support: L-glutamine plays a central role in muscle repair and immune function, which are compromised following high-intensity exercise. 

• Sleep and mood support: L-tryptophan is the dietary precursor to both serotonin and melatonin, supporting the sleep quality that is essential for tissue repair and growth hormone release. 

• Antioxidant defence: L-cysteine helps neutralizing the oxidative stress generated by intense exercise. 

• Energy and electrolyte restoration: A glucose and fructose combination initiates carbohydrate replenishment, alongside a full electrolyte profile supporting fluid balance, nerve conduction, and muscle contractility.
 
• Micronutrient support: vitamins B6 and B12 support energy metabolism, while zinc and selenium contribute to immune defense and antioxidant enzyme activity. 
 
7. Are the powder sachets and push-cap bottle 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.
