EndurPro™ is the practitioner-exclusive nutraceutical line created by Endurance Products Company—an Oregon-based legacy brand trusted since 1978. Built on nearly five decades of scientific innovation, the new EndurPro™ line is designed to elevate how health providers support their patients, delivering a new standard of targeted nutrient delivery.
The Challenge: “Dose Dumping” in the SR World
For decades, most “sustained-release” supplements have delivered nutrients unpredictably—releasing too fast, too slow, or at the wrong time in the digestive tract. The industry never truly solved controlled, therapeutic nutrient delivery… until now.
The Breakthrough: SmartMatrix™ Technology
Developed in 1976 by biochemist Terry Hammerschmidt, SmartMatrix™ is a proprietary vegetable-wax matrix that encases nutrients—not coats them—protecting them from stomach acid and transporting them directly to the GI tract for steady 6-8 hour absorption. This technology is supported by decades of clinical research and delivers up to 99% of active nutrients—far higher than standard tablets.
Why it matters
• More consistent therapeutic levels
• Better patient compliance
• Fewer daily doses
• Enhanced bioavailability
• Cleaner, minimally processed tablet with fewer irritants
EndurPro™

Supplements for
Healthcare
Practitioners
SmartMatrix™ is a proprietary tablet manufacturing process where water-soluble nutrients are encased (not coated) in a vegetable wax matrix core that ushers them directly into the GI tract where they can have the greatest impact. That’s right; nonstop transit to the gut, where nutrients are most readily absorbed, and reliably leech into the bloodstream over 6-8 hours. SmartMatrix™ has been proven in clinical studies to deliver up to 99% of the active ingredients in a tablet, not a lesser percentage like ordinary tablets. So SmartMatrix™ delivers more nutrients to the GI tract, facilitates optimal absorption and tissue retention, plus eliminates side effects from mystery polymer coatings. That scientifically validated and proprietary process is at the core of our unique SmartMatrix™ technology featured in every Endur and EndurPro supplement.
By the 1980s, Harvard scientist Dr. Frank Sacks researched the effects of niacin on cholesterol. He discovered that Hammerschmidt’s unique vegetable wax matrix technology reduced the common side effect of “flushing,” a temporary redness and warmth that feels like a mild sunburn and lasts about 30 minutes. This study not only highlighted the ability of niacin to support healthy cholesterol balance, but it also showed significantly reduced flushing. As a result, our innovative wax matrix technology gained recognition from researchers at multiple universities. Over time, it has led to over 23 published studies in collaboration with esteemed institutions such as:
• 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
Our controlled release technology became popular for its ability to provide a slow, steady release of nutrients.
Our proprietary vegetable wax matrix technology has been featured in several well-known books, including The 8-Week Cholesterol Cure, The New 8-Week Cholesterol Cure, The Blood Pressure Cure, Cholesterol Without Diet: The Niacin Solution, The Niacin Breakthrough, Ulcer Free!, and The Tubby Factor.
Endurance Products Company has Been
Family-Owned and Operated Since the Start
What began with Terry’s early research grew into a 47-year partnership with CEO Joe Brunner, producing a full suite of clinically validated supplements for consumers under the Endur™ name—highlighted by by ENDUR-ACIN™, a flagship cardiovascular formula.

Dihydroberberine SR with Glucovantage®
Approximately 7.4 million adult Americans take insulin to manage their diabetes. That is over 37 million Americans living with this debilitating health challenge. Many more also require insulin for the treatment of type-1 diabetes. This is where the body doesn’t produce insulin on its own.
- The National Diabetes Statistics Report provides up-to-date
information on the prevalence and incidence of risk factors. - While data and reports can help to focus efforts to prevent and control diabetes across the United States and globally, there are clinically substantiated natural options that can impact human lives right now.
What is the insulin hypoglycemic effect?

Dihydroberberine with Glucovantage® may help to promote glucose balance, lipid metabolism, and heart health
Like millions of Americans, blood sugar balance may be a health priority for you.
If so, you’ll want to know about clinically substantiated nutraceutical options that can help
maintain blood sugar in the normal range. Berberine is one such option.
What is the berberine effect?
Your ability to maintain blood sugar in the normal range can occur through various mechanisms, including supporting glucose uptake by tissues, helping maintain normal glucose production by the liver, or by promoting insulin sensitivity. The ability of berberine to support blood glucose balance has been widely studied. This action is largely attributed its ability to support mitochondria function, stimulate glycolysis, and activate the AMPK pathway that transports glucose into peripheral tissues.
