Co-Founder & Chief Nutrition Officer
Dr. Marc Bubbs spent decades as a clinical and performance nutritionist, working alongside professional and Olympic athletes as well as consulting for Fortune 100 companies and becoming a best-selling author. During his time in locker rooms and training facilities, he saw time and time again as athletes struggled to find supplements that provided reliable results.

Founder and CEO
Paul Winsper built his career climbing to the highest levels of sport, working with athletes across multiple major leagues. His approach is rooted in the belief that an athlete’s health is the real foundation of sustained elite performance. He too saw a pattern—world-class athletes underserved by nutrition.
ProBio wasn't built to be the biggest name in the category. It was built to keep athletes available when others are sidelined. We exist to protect the work. Every decision we make starts with the athlete and ends with the evidence. Practitioner-designed. NSF Certified for Sport. No proprietary blends. No hidden dosages. No claims we can't back up. That’s why athletes trust us.

Athletes are our reason for being and the inspiration behind our innovative delivery systems, which are designed to make compliance with their ProBio regimen as simple as possible.
Everything we offer is based on proven science, ensuring athletes get the effective results they want, without ingredients they don’t need. We care about athletes’ ability to compete at the highest level, which is also why we are proud to be NSF Certified.
With all the pseudoscience out there, athletes need expertise they can trust. We keep things simple, and explain our ingredients and benefits clearly, so nothing gets in the way of what we set out to do, and what our athletes set out to achieve.
Elite athletic performance demands more of the human body —more biological systems working together to keep athletes ready to compete. Our goal is to make holistic health easy to achieve so athletes can focus on what they love most.
Simply put, the best goes in to get the best out. Meaning we source only premium, natural, whole-food derived ingredients—free of artificial flavors, sweeteners and dyes. Our commitment to transparency also means we work with only best-in-class suppliers so you can feel confidence about what’s in every scoop.
