How does NSI® Quebracho Bark Extract work?
Made from one of the hardest woods in existence, the South American Quebracho tree is reported to have destroyed many axes (in fact, Quebracho's Spanish translation literally is “The axe breaks"). The extract derived from its bark contains antioxidant compounds so potent, they are believed to have destroyed even more free radicals.

ORAC is a method of rating the antioxidant capacity of foods. The higher the ORAC rating an item has, the higher its antioxidant activity. About 400 mg of quebracho extract per day supplies 5,200 ORAC units.  NSI® Quebracho Bark Extract is a powerful antioxidant that may offer numerous health benefits, including cardiovascular, immune and vision health, and may also support healthy aging.
  
Quebracho bark extract may support cardiovascular health and blood circulation by helping to strengthen blood vessel walls and capillaries, and by helping to prevent stress-induced constriction of arteries and blood clotting. It supports healthy aging by helping protect collagen and maintain elastin, which contribute to healthy skin, joints, blood vessels, ligaments, tendons, muscles and hearts. In addition, quebracho bark extract may also enhance healthy brain function and the capacity to exercise, while it works to relieve inflammation.

-- Has a high ORAC value, meaning that it has powerful, effective antioxidant capabilities.
