According to the USDA, the ORAC method for testing antioxidant capacity was withdrawn from official publications in 2012 due to a lack of evidence linking in-vitro results directly to in-vivo health benefits. However, the ORAC assay procedure continues to be utilized in various research fields and for commercial product comparisons.

First developed by scientists at the National Institute on Aging, the ORAC assay was once a widely used method to measure antioxidant capacity. The core of how ORAC works involves exposing a sample to free radicals and measuring its ability to absorb and neutralize them in a controlled laboratory setting.

Developed by scientists at the National Institutes of Health (NIH) and the USDA, the Oxygen Radical Absorbance Capacity (ORAC) scale was a laboratory test to measure the total antioxidant power of various foods. While once heavily marketed, its official use has been abandoned due to misleading interpretations and a lack of correlation between lab results and human health benefits.
