Dr. Spencer Nadolsky, MD
Board-Certified Family Medicine Physician, a Diplomate of the American Board of Obesity Medicine, and Legion Advisory Board Member"There are a lot of sleazy supplement companies out there, but Legion is not one of them. Their products are free of fillers and inactive ingredients and they take the time (and money) to test them with independent labs to ensure you're getting what you pay for."

Menno Henselmans, MS
Founder of Bayesian Bodybuilding, Published Scientist, Physique Coach, and Legion Advisory Board Member"Legion consults with nutrition experts to make honest, science-based products and then proves they're genuine with independent lab work. That's how all supplement companies should operate."

Dr. Bill Campbell, PhD
Professor of Exercise Science at University of South Florida and Legion Advisory Board Member"Many supplement companies claim they're ‘evidence-based’ and try to impress you by throwing a few scientific references on their product pages. Legion is science-based at its core. Not only do they dose all of their products based on the clinical doses proven to be effective by scientific studies, they go above and beyond the their competitors by funding new research. They don't just want to sell you supplements--they want to change the supplement industry for the better."

Published Scientist, Author, and Speaker"There are three reasons I like Legion. First, they use ingredients backed by independent, peer-reviewed scientific studies. Second, the quality of their supplements exceeds many in the industry and you know you’re getting what’s on the label. Third, Mike Matthews is a solid evidence-based guy who doesn’t over-hype."
