We exist, so athletes can keep showing up.

Our Story

Backed by science

“Together, we created ProBio to fill the gaps with a formula that’s backed by science and doesn’t shy away from transparency.”

Dr. Marc Bubbs

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.

Paul Winsper

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.

Our Purpose

Our standard is non-negotiable.

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.

Elite nutrition, built for everyday performance.

Our Values

We value real athletes, real science and real results

01 — Athlete-Inspired
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.
02 — Evidence Backed
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.
03 — Simple & Transparent
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.
04 — Holistic & Integrated
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.
05 — Only The Best For The Best
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.
