OIKOS announced a multi-year partnership with professional tennis star and five-time Grand Slam champion Carlos Alcaraz, who will serve as its global brand ambassador.

Alcaraz is teaming up with OIKOS to showcase how a foundation of healthy habits, exercise, and balanced nutrition, paired with the brand's variety of delicious, protein-packed options, can help fuel your unique strength journey.  

"Strength is an important factor to me, both on and off the court. But it's not just about how I train – it's about how I fuel my body," said Alcaraz. "That's why I'm proud to partner with OIKOS. Its high-quality protein is one of the things that helps me maintain my strength."

"At OIKOS, we're committed to fueling all kinds of strength – not just for elite athletes like Carlos Alcaraz but for anyone showing up and giving it their all," says Victoria Badiola, Vice President of Greek & Functional Nutrition at Danone North America. "Alcaraz embodies the OIKOS spirit with his grit, resilience, and energy, and we couldn't be more excited to welcome him to the team."

To celebrate the partnership, OIKOS has curated the ultimate "drop kit" which will feature select gear, including a co-branded tennis bag and hat with Carlos Alcaraz's signature, OIKOS-branded socks, sweatbands, tennis balls, and a fan-favorite muscle recovery tool. The kits will debut on social this August, just in time for one of the biggest moments in U.S. tennis, with more to come from Alcaraz in 2026.
