Klean Athlete


When your background is producing superior-quality nutritional supplements for healthcare professionals, you begin to wonder: Who else can benefit from your knowledge and experience? When this simple question was posed to our practitioner partners, it led us to an important discovery: Some of the world’s top athletes had been relying on the quality and heritage of Atrium Innovations' healthcare practitioner brands for nutritional supplements to support their athletic endeavors. In fact, we've shipped all over the globe to athletes competing in some of the world's most challenging and prestigious sporting events.

Manufacturing expertise and an already eager group of athletes paired with our personal passion — the decision was simple. And now, here we are: Klean Athlete, a collection of very active individuals who are proud to work for an innovative and growing nutritional supplement company. We are athletes, from marathoners to IRONMAN finishers, century riders to adventure racers, hockey, baseball and soccer players and even yogis. Sure, we like to watch — but prefer to train and compete!

Klean Athlete products are manufactured through a simple paradigm: provide formulas that are proven through sound science, support your active lifestyle and give you everything you need — and nothing you don’t. The complete line is formulated without wheat or gluten and contains no artificial coloring, flavoring or sweeteners. Our line of nutritional supplements are tested and certified through our partner, NSF International, and their prestigious NSF Certified for Sport program.

Whether amateur or professional, athletes are always pushing it to the limit and looking for the next best product to help them achieve their goals. Our approach promotes peak performance by building a solid nutritional base as a support system for athletes' overall well-being. Our products can be taken daily and are bundled into three categories: Foundation, Train & Compete and Targeted. Each group is meant to complement one another while allowing you to find the best fit for your nutritional needs.


Klean Athlete is tested and certified by the NSF Certified for Sport program, which was created to meet the growing demands of athletes, coaches and healthcare professionals to certify that sports supplements are safe and free from banned substances.
