Nutrabolt, the owner of sports nutrition brand C4, has partnered with Philadelphia Eagles running back Saquon Barkley to drive awareness of the pre-workout supplement C4 Sport.

After a breakout season in which Barkley was one of the top NFL rushers in 2024, Barkley will step into the new season with great expectations placed upon him, Nutrabolt said, noting that he is celebrated for his explosive athleticism, unwavering commitment, and treating his body ‘like a temple.’

C4 Sport is NSF Certified for Sport, which is recognized by athletes as assurance that a product doesn’t contain substances banned by athletic organizations. The formula features clinically studied ingredients for energy and muscular endurance, along with three electrolytes.

“All top athletes are always looking for ways to get better,” said Barkley. “As a fan of the brand, I use C4 Sport because it gives me the energy, focus, and endurance I need to attack every workout and stay at the top of my game. Knowing it’s NSF Certified for Sport means I can trust it is safe, tested, and approved for game day. I couldn’t be more excited to partner with C4, a brand that I’ve used for years and always keep with me for training.”

The partnership will spotlight how C4 powers Barkley’s training, prepares him for game day, and helps him push past his limits on and off the field, with exclusive content, behind-the-scenes looks at his workouts, and giveaways, all of which will offer unique access to his fitness regimen and the products that fuel it.

“At Nutrabolt, we’re dedicated to delivering high-performance products that give athletes a competitive advantage. C4 Sport elevates their training experience, gets them ready to perform, and fuels athletes on gameday,” says Robert Zajac, chief marketing officer at Nutrabolt. “Partnering with Saquon Barkley is a natural fit, as his relentless drive and commitment reflects the core values of our brand. All our NSF Certified products, including C4 Sport, give athletes at all levels the trusted, safe fuel they need to push their limits.”
