What is ORAC?
ORAC stands for Oxygen Radical Absorbance Capacity. ORAC measures the ability of just about any substance to subdue oxygen free radicals in the test tube. In short ORAC is a lab assay that can measure the antioxidant activity of any substance and give it a number. The higher the ORAC number- the stronger the antioxidant properties of the substance.
National Institute on ASging developed the ORAC method and the US Department of Agriculture and Brunswick Labs have been instrumental in perfecting the ORAC assay procedure and testing various foods to determine ORAC levels.
