KA-EX Creatine EAA+ Booster is the first ready to drink (RTD) creatine product that actually delivers a full clinical dose — intact, potent, and ready to work the moment you crack it open. But that's not all, Creatine EAA + Booster delivers caffeine, L-citrulline, betaine, and electrolytes to stamp itself as a well-rounded high performance formula.
Creatine That Actually Survives the Bottle – Powered by a patented VICAP® push-cap system, the full 3g dose of Creapure® creatine is stored dry in the cap and released into the liquid only at the moment of consumption. No degradation. No wasted dose.
A Complete Pre-Workout Stack in One Serving – This isn't just creatine. Each serving combines Creapure® creatine with essential amino acids (the building blocks your muscles need to repair and grow), caffeine for focus and alertness, L-citrulline for blood flow and endurance, betaine for power output, and electrolytes — including magnesium, calcium, and potassium — to keep your muscles firing.
Swiss Pharmaceutical Engineering – Developed by ETH Zurich-trained scientist Pedro Schmidt after five years of clinical research, KA-EX applies pharmaceutical-grade thinking to performance supplementation. The VICAP® technology actively protects ingredients from UV light and chemical degradation, preserving potency through the full shelf life.
Creatine is one of the most researched supplements in sports science. A daily intake of 3g supports greater power output and faster ATP regeneration — the energy system that drives every sprint, interval, and heavy lift. L-citrulline widens blood vessels to push more oxygen to working muscles, while the full spectrum of essential amino acids prevents muscle breakdown during hard efforts. Together, they cover the pre-workout window from energy to endurance to muscle protection.
RTD Bottle: Press the VICAP® push-cap to release the creatine dose into the liquid, shake briefly, and drink 15–30 minutes before training.
Daily Consistency: Creatine works through daily accumulation — take it every day, including rest days, to maintain elevated muscle stores. Pro tip: pair it with KA-EX Cortisol Stress Reducer post-workout for full-cycle performance support.
Trusted by thousands of professional athletes, teams, and high-performers worldwide — from Olympic competitors to F1 drivers — KA-EX has built its reputation on clinical validation and ingredient transparency.
1. What is KA-EX® CREATINE EAA+ BOOSTER and how does it work?
KA-EX® CREATINE EAA+ BOOSTER is a high-performance pre- and intra-workout formula designed to support energy output, focus, blood flow, and muscular endurance during intense training.
The formula targets three distinct performance levers simultaneously:
Power output and strength: Creapure® creatine monohydrate — the most clinically validated form of creatine, manufactured to pharmaceutical standards — increases physical performance in successive bursts of short-term, high-intensity exercise by replenishing phosphocreatine stores, the immediate energy currency of explosive muscular contractions.
Blood flow and endurance: L-Citrulline supports nitric oxide production through the arginine pathway, while organic beetroot extract contributes dietary nitrates that convert to nitric oxide via a separate mechanism. Together, they support vasodilation and blood flow during exercise, contributing to oxygen supply to working muscles throughout the session.
Focus and alertness: Caffeine helps to increase alertness, improve concentration, and contributes to short-term physical performance, helping you stay sharp from the first rep to the last.
Betaine further supports these three pillars by targeting the same ATP resynthesis pathway as creatine for a compounding power effect. EAAs ensure amino acid availability during the session. A full electrolyte panel — magnesium, calcium, potassium, and sodium — contributes to normal muscle function, normal nerve function, and electrolyte balance, providing the operating environment that muscle contractions, nerve signalling, and hydration all depend on.
2. When should I take KA-EX® CREATINE EAA+ BOOSTER?
KA-EX® CREATINE EAA+ BOOSTER is designed to be taken immediately before or during training to support performance from the moment your session begins.
3. Creatine is unstable in water - how does KA-EX® CREATINE EAA+ BOOSTER keep it effective in a ready-to-drink bottle?
Creatine rapidly converts to creatinine - an inactive waste product - when stored in liquid, especially in the acidic conditions of flavoured drinks. This makes it challenging to have a creatine ready to drink product on the market.
KA-EX® CREATINE EAA+ BOOSTER is the world’s only creatine RTD thanks to the VICAP technology: Creapure® creatine is stored dry inside the push-cap until the moment you activate it. No contact with water during shelf life means zero degradation. You get the full 3g of active creatine, every time.
4. 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, such as creatine.
5. KA-EX® CREATINE EAA+ BOOSTER has zero sugar — so where does the energy come from?
KA-EX® CREATINE EAA+ BOOSTER delivers performance through ingredients that work directly with your body's own energy systems.
Creatine replenishes the phosphocreatine levels your muscles use for explosive efforts. Caffeine helps to increase alertness and improve concentration, reducing perceived effort during training. L-Citrulline and beetroot extract support nitric oxide production and blood flow, contributing to oxygen supply to your muscles throughout the session.
The result is sustained, clean energy. No sugar means no spike, no crash, and no impact on blood glucose or insulin before training, making it suitable for any athlete, at any time of day.
It’s Science baby
Caffeine supports short-term physical performance and helps improve concentration and alertness.
Creatine increases physical performance in successive bursts of short-term, high-intensity exercise when a daily intake of 3 g is achieved.
Magnesium and potassium contribute to the normal functioning of the nervous system, while calcium contributes to normal neurotransmission.

FAQ
Why does KA-EX® usepush-cap technology?
Uncompromised nutrition meets unmatched absorption. KA-EX® uses a patented dual-chamber push-cap system that keeps sensitive ingredients separate from the liquid until the moment of use, ensuringoptimalstability and absorption. Thanks to this technology, nutritional substances are thoughtfully paired and protected from UV light and chemical degradation.
Why does KA-EX® come in powder sachets?
Uncompromised nutrition meets unmatched absorption. KA-EX® comes in powder sachets that keep sensitive ingredients separate from liquid until they are mixed, ensuring optimal stability and absorption. Each unit is packed with light- and air-tight in an aluminum bag, helping preserve the quality of the vitamins and other nutrients over time.
This approach allows nutritional substances to be thoughtfully paired and protected from UV light and chemical degradation, while offering a flexible and convenient solution for use on the go.
Is KA-EX® clinically tested?
Yes, KA-EX® has been evaluated in three studies, including work conducted with the Swiss National Football Team and research carried out by an independent Contract Research Organisation (CRO).KA-EX was shown to accelerate cortisol normalization by 36%, improve REM sleep by 16%, and enhance heart rate variability (HRV) by 10%-resulting in more energy (9%) and an 8% improvement in mood.
How does KA-EX® support athletes’ performance and recovery?
KA-EX® is designed to support recovery and overall performance by helping the body cope with physical and mental stress associated with exercise. Its formulations combine electrolytes, carbohydrates, vitamins, amino acids, and other bioactive substances to support hydration, energy metabolism, and key recovery processes after training or competition.
By supporting cortisol regulation and key aspects of recovery such as muscle recovery, hydration, and cognitive function, KA-EX® Cortisol Stress Reducer helps athletes maintain consistency in performance across repeated training sessions and demanding schedules.
For performance, KA-EX® Boost+ combines ingredients such as creatine, amino acids, caffeine, and electrolytes to support power, endurance, focus, and overall physical energy during exercise.
