ABOUT ENDURANCE PRODUCTS CO.
Time-tested and customer-approved, Endurance Products Company has been a well-trusted and well-loved source of quality dietary supplements since 1978.
Our History
Family-Owned and Operated Since the Start
Endurance Products Company has led the supplement industry for over 45 years, delivering top-quality products rooted in research while staying true to our founding vision. Today, the Brunner family owns and operates the business alongside founder Terry Hammerschmidt.
In the late 1960s, our founder, Terry Hammerschmidt, a biochemist and former collegiate athlete, pioneered our sustained-release technology. Drawing on his pharmaceutical expertise, he adapted controlled-release methods for vitamins and supplements.
In the 1980s, Harvard’s Dr. Frank Sacks studied niacin’s cholesterol benefits using our vegetable wax matrix technology. His research showed it supports healthy cholesterol levels while significantly reducing flushing—a mild, temporary redness.
Endurance Product Company's revolutionary wax matrix technology earned top recognition and popularity from university researchers for its steady, or sustained, release of nutrients. Today, it has driven 23+ published studies in collaboration with leading institutions like:
- Harvard
- The University of California
- The University of Minnesota
- Oregon Health & Science University
- Brown University
- Iowa State
- Utah State
- West Virginia University
- and others internationally
