We’re proud to officially welcome Zach Bitter to the ProBio family!
One of the most respected ultramarathon and endurance runners in the sport, Zach has spent years pushing the limits of human performance. But pushing the limits of human performance isn’t just race-day grit—it’s about the consistency and discipline of training and recovering to deliver results.
That’s the same philosophy that led us to build ProBio ProBlend: foundational nutrition that consistently works, without the noise. And we’re proud that it’s part of Zach’s daily routine.
One scope of ProBlend replaces the typical supplement regimen with a single, science-backed formula designed for those who train with purpose—whether you’re logging 100-mile weeks or chasing progress one workout at a time.
