Endurance for every activity.
All day, every day.
The Endurance Performance Bundle is designed to support energy, focus, hydration, and performance with three advanced sustained-release supplements: ELECTROLYTE SR, TAUROMAG® SR, and ENDUR-B® SR. Powered by SmartMatrix™ sustained-release technology, each formula delivers nutrients gradually over 6–8 hours for longer absorption, steadier energy, and consistent support—without the spikes and crashes of fast-release supplements.* Built to fuel performance that lasts.

I’m a big fan of Endurance Products Company for their high-quality ingredients, scientific backing, and integrity. They also make my favorite niacin product, Endur-acin—a unique wax matrix formula I trust for naturally lowering cholesterol particle number.

Dihydroberine has been a game-changer for my patients. Women taking it have lost 5–8 pounds without any lifestyle changes. I've seen inflammation markers drop, weight decrease, and cholesterol improve—confirmed by lab tests.

Endurance multi-vitamins are the first vitamins I've taken that don't make me feel nauseous.
-Barbara A.
The Sustained Release Electrolye pills are a game-changer for my wife and I. Have been using these for a few years now, and plan to continue for many years to come.
-Longtime Fan
Great vitamin C and I never have stomach issues with this brand!
-Lisa M.
I have used various products and this Endurance product seems to help me the most. Not sure why...I'm not a chemist...my joints aren't as stiff in the morning, so there it is.
-Janet R.
My PCP first brought to my attention the idea of "pre-biotic" - Endurance Products' Prebiotic Plus has been a life changer.
