Swiss Supplement Innovator KA-EX Names Swiss Tennis Star, Olympic Gold Medalist Belinda Bencic, Brand Ambassador and Investor

The partnership accelerates the performance brand’s continued expansion into professional athletics in the U.S.

NEW YORK — Swiss supplement innovator KA-EX today announced a partnership with Belinda Bencic, Olympic gold medalist and one of Switzerland’s most decorated professional tennis players. She joins the brand as an investor and Global Brand Ambassador, a deal that marks a major milestone in KA-EX’s continued growth strategy within the U.S. and internationally.

Bencic, who has reached a career-high ranking of World No. 4, won the women’s singles gold medal at the Tokyo 2020 Olympic Games and boasts multiple WTA singles titles throughout her career. She will represent KA-EX through a range of brand, social, media and event initiatives, while supporting the company as an investor. As KA-EX continues to establish itself as a global player in the performance supplement space, the deal strengthens brand credibility among high performers and athletes.

The partnership is grounded in Bencic’s own experience with KA-EX products, which she began incorporating into her training routine earlier in 2026, at the urging of her athletic trainer. She cites noticeable benefits to her performance and recovery, touting KA-EX Creatine EAA Booster (which combines creatine and essential amino acids to support the demands of high-performance training) as a staple in her routine.

“Belinda is an incredible athlete who has consistently ranked among the world’s best tennis players. After the birth of her daughter, she made an extraordinary comeback, going from unranked to the Top 50 in less than a year and the Top 10 in less than two years. An almost unbelievable achievement, and she approaches performance, recovery and athletic excellence in a way that closely aligns with our mission,” said Pedro Schmidt, CEO and Founder of KA-EX and ETH Zurich-trained pharmaceutical scientist. “Her ambition and discipline, coupled with the fact that she was already a genuine KA-EX user, makes the relationship even more meaningful.”

Bencic’s addition to KA-EX’s roster of elite athletes (which includes the Tudor Pro Cycling, Serie A football, the Swiss Super League, and Swiss National League ice hockey) reinforces the company’s mission to bring Swiss-engineered performance nutrition to an international stage.

“I believe in the KA-EX products and have experienced the difference they can make for training and recovery firsthand,” said Belinda Bencic. “Performance at the highest level of sport isn’t limited to what happens on the court. It’s about how I recover and support my body’s demands. Incorporating KA-EX products was one of the easiest decisions, and the Creatine EAA+ Booster helps ensure I can perform with power and recover quickly.”
