Top 300 ORAC Values: Antioxidant Values of Foods & Herbs

by Sean Martu

What are ORAC Units?

The ORAC (Oxygen Radical Absorbance Capacity) unit, ORAC value, or “ORAC score” is a method of measuring the in vitro antioxidant capacity of different foods, herbs, and supplements. It was originally developed by scientists working at the National Institutes of Health (NIH) and USDA. Measuring in vivo (meaning inside the human body) is not possible and for that reason, the exact relationship between the ORAC value of a food/supplement and any suspected health benefit it may have as a result is inconslusive. However, many scientists theorize that foods higher on the ORAC scale may be more effective at neutralizing free radicals. Although unproven, according to the free-radical theory of aging, this may slow the oxidative processes and free radical damage that contributes to age-related degeneration and diseases.
