Founded by biochemist Terry Hammerschmidt, Endurance Products Company has sold a wide range of clinically researched dietary supplements for over 47 years. In 1976, after dozens of exploratory studies, the SmartMatrix™ tableting technology was born. SmartMatrix™ is our proprietary 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 on human health. That’s right; nonstop transit to the gut, where nutrients are most readily absorbed, and reliably leach into the bloodstream up to 6-8 hours. So SmartMatrix™ delivers more nutrients to the GI tract, facilitates optimal absorption and tissue retention, plus eliminates side effects from mystery polymer coatings.
