Oxygen Radical Absorbance Capacity (ORAC) is a method of measuring antioxidant capacities in biological samples. Antioxidants are substances that neutralize free radicals, the damaging compounds produced by metabolism and exposure to toxins and radiation. Free radical damage causes most of the changes we associate with aging, and it can lead to inflammation, cardiovascular and nervous system damage, impairment of immune function, and even cancerous changes in cells.
The level of antioxidant activity in a food or supplement is measured by its ORAC score. The higher the ORAC score, the more potent the antioxidant activity. The following graph shows the extraordinary antioxidant strength of the Maqui berry compared to other superfruits.
