O.R.A.C. – What does it mean?

August 14, 2009

O.R.A.C. stands for Oxygen Radical Absorbance Capacity. It is an experimental lab test that measures the antioxidant potential of foods and nutraceuticals, i.e. it is basically an estimate. It would be easy to formulate a product with a high ORAC, but it is unclear what this means in an intact biological system (as in the human body) because no studies have been done monitoring any health benefits from a defined ORAC “number” intake over any period of time.

In other words, ORAC measures “potential,” but is no guarantee of biological activity. Juice Plus+® has been published in clinical studies proving bioavailability in humans rather than in vitro (literally “in glass”). There are currently fifteen published studies showing the benefits of taking Juice Plus+® along with fifteen years of use around the world.

Juice Plus+® has been shown over and over to increase known antioxidants like Vitamin C, Vitamin E, Alpha-tocopherol and Beta-carotene in blood circulation, and has been shown to decrease markers of oxidation in the blood as well. These are actual, direct measurements, done with real people taking Juice Plus+® and are more reliable and meaningful than an isolated ORAC number done in a test tube.

You can view the abstracts of the research reports that include functional assessments of antioxidant activity in Juice Plus+® at the Juice Plus+® research website.
