Scientific Advisory Board

Our scientific advisory board guides the scientific direction of Legion.

It’s comprised of researchers, scientists, and thought leaders. Rather than endorsing individual products, they advise the Legion team on product identification and development, relevant clinical studies, and ongoing research.

Scientific direction

The board advises on improving existing and new formulations, translating published research into potential products, and pursuing new avenues of research.

Product discovery

Legion’s board members participate in various fields of study, including protein metabolism, muscle hypertrophy, and exercise performance. They also work in a variety of roles such as obesity specialists, nutritionists, clinicians, and scientists, and their expertise and experience allows Legion to research and create superior, scientifically validated products.

institutional connections

Our board's relationships with academic institutions like the American Journal of Clinical Nutrition, the International Sports Sciences Association, and the Journal of the International Society of Sports Nutrition give us access to intellectual property, the opportunity to sponsor clinical trials, and connections to top researchers.

Board Members

Dr. Spencer Nadolsky

Board Certified Family Medicine Physician
and a Diplomate of the American Board of Obesity Medicine

Dr. Nadolsky's love for using lifestyle as medicine arose out of a passion for sports, where he used exercise and nutrition science to become the heavyweight wrestling champion at UNC Chapel Hill.

During medical school, Dr. Nadolsky attended multiple obesity medicine conferences and realized that the same exercise and nutrition principles used for improving sports performance could also be used by the general public to combat obesity, diabetes, and other lifestyle diseases.

To further hone his skills, Dr. Nadolsky attended VCU’s Riverside Family Medicine Residency in Newport News, Virginia. He is the author of The Fat Loss Prescription, and now practices medicine online via SteadyMD, a pioneering new system for delivering remote medical care.
