KA-EX Uncaps a Solution to Creatine's Biggest Stability Problem

NEW YORK, NY – April 28, 2026 – Swiss supplement innovator KA-EX has officially entered the competitive U.S. functional beverage market with a product that tackles one of the industry's most persistent chemical challenges. The company today launched its Creatine EAA+ Booster, a next-generation energy drink that marks the arrival of what it calls the first truly stable, ready-to-drink (RTD) creatine beverage.

For years, the convenience of a pre-mixed creatine drink has been undermined by a simple fact of chemistry: when creatine monohydrate is suspended in water for extended periods, it degrades into an inactive byproduct called creatinine. This meant that by the time a conventional RTD creatine product reached a consumer, its potency could be significantly diminished. KA-EX is betting it has solved this billion-dollar problem, not with a new chemical formulation, but with a clever feat of engineering.

Solving the Creatine Conundrum

The cornerstone of the new Creatine EAA+ Booster is its patented VICAP® push-cap technology. This dual-chamber system stores a full clinical dose of 3 grams of Creapure® creatine—a form renowned for its 99.9% purity—as a dry powder within the cap, completely separate from the liquid below. At the moment of consumption, the user pushes the cap, releasing the powder to be mixed into the drink. This ensures the creatine remains stable and at maximum potency, delivering on the promise that what's on the label is what the consumer actually gets.

This innovation directly addresses the stability issues that have plagued the development of effective creatine RTDs. While some brands have tried to mitigate degradation by altering pH levels or using less-researched forms of creatine, KA-EX's mechanical solution preserves the integrity of creatine monohydrate, the most studied and validated form of the supplement. By isolating the active ingredient until the last possible second, the technology effectively sidesteps the degradation process that occurs during shipping and on store shelves.

“Creatine is having a mainstream moment,” said Pedro Schmidt, CEO and Founder of KA-EX and an ETH Zurich-trained pharmaceutical scientist, in a statement. “Awareness has expanded well beyond the gym, driven by a growing body of evidence around cognitive performance, healthy aging, and everyday energy... Now, we’re providing consumers with an option they haven’t had before – creatine in a convenient ready-to-drink format that actually delivers what it says on the label.”

A Complete Performance Formula

Beyond its innovative delivery system, KA-EX has positioned the Creatine EAA+ Booster as more than just a pre-workout. The Swiss-engineered formula is designed as a comprehensive performance tool to support users before, during, and after physical or mental exertion. Each sugar-free bottle contains a synergistic blend of research-backed ingredients.

In addition to the 3 grams of Creapure® creatine, the drink includes:

• 3.5g of Essential Amino Acids (EAAs): The full spectrum of all nine EAAs to support muscle protein synthesis, repair, and recovery.
• 1g of L-Citrulline: An amino acid known to support nitric oxide production, which can enhance blood flow, improve endurance, and delay fatigue.
• 105mg of Caffeine: A moderate dose, roughly equivalent to a standard cup of coffee, to enhance alertness and focus without excessive stimulation.
• A Complete Electrolyte Complex: A blend of sodium (500mg), potassium (370mg), magnesium (57mg), and calcium (115mg) to support hydration and normal muscle function during training.
• Functional Plant Compounds: 500mg of Betaine, 300mg of Beetroot Extract, and 60mg of Grape Skin Extract are included to further support performance and recovery pathways.

This multifaceted formulation aims to simplify an athlete's or high-performer's supplement routine, combining the benefits of a pre-workout, an intra-workout hydration mix, and an amino acid supplement into a single, convenient bottle.

Tapping into Creatine's Mainstream Moment

The launch is timed perfectly to capitalize on creatine's rapidly expanding appeal. Once the domain of bodybuilders and elite athletes, the supplement is now being embraced by a much broader demographic for its wide-ranging benefits. The global creatine market, valued at over $1.13 billion in 2024, is projected to surge to nearly $10.78 billion by 2034, registering a compound annual growth rate of over 25%.

This explosive growth is fueled by a growing body of scientific research highlighting creatine's role in areas beyond muscle mass. Studies have shown its potential to enhance cognitive functions like short-term memory and processing speed, particularly under stress or sleep deprivation. For older adults, it may help combat age-related muscle loss (sarcopenia) and support cognitive health. This has opened the door for new user groups, including students, professionals, women, and aging individuals seeking to maintain both physical and mental vitality.

The convenience of KA-EX's RTD format is a direct response to this market shift. It lowers the barrier to entry for those who may be unfamiliar with or intimidated by traditional powders and mixing protocols, making the supplement's benefits more accessible for daily use.

A Strategic Push into the U.S. Market

The Creatine EAA+ Booster is the second major move in KA-EX's strategic expansion into the United States. The brand first entered the market in the summer of 2025 with its Cortisol Stress Reducer, a post-workout recovery drink that has reportedly become a top-selling product at specialty retailers like Earthbar within Equinox gyms and on e-commerce platforms like The Feed. The new creatine booster now provides a pre- and mid-workout counterpart, creating a complete system that supports the entire training and recovery cycle.

A critical component of this expansion is a new flagship national retail partnership with GNC. The Creatine EAA+ Booster will be available in GNC stores and online nationwide, giving KA-EX immediate and substantial access to a customer base that values scientifically validated products. For GNC, the partnership adds an innovative, high-tech product to its shelves that aligns with its focus on premium, research-backed nutrition. This collaboration provides KA-EX with significant credibility and a powerful distribution channel to compete in the crowded but lucrative U.S. supplement landscape.

The product is available now in its RTD format and as ready-to-mix sachets on the company's website and The Feed, with availability on Amazon to follow in mid-May, before the nationwide rollout at GNC. This multi-channel approach signals a confident and aggressive strategy to establish KA-EX as a major player in the next generation of functional wellness.
