ORAC Information

ORAC is the Oxygen Radical Absorbance Capacity of food.

ORAC provides us with a method of measuring the overall antioxidant power of foods and supplements. Antioxidants are essential to good health, especially with respect to aging and age related disorders. Scientists have learned that phytochemicals, including antioxidants, increase our resistance to disease and boost immunity. Hence the recommendation of 5-9 servings of fruits and vegatables each day.

Simply put, the higher the ORAC value of food the more antioxidant power it contains.
The focus on "foods" is significant as scientists have found that antioxidants are most effective when received from a whole food.

The chart below shows the fruits and vegetables found to be highest in antioxidants.The higher the ORAC number, the greater the amount of antioxidants in the food.

3,000 to 5,000 ORAC units per day are required.

Studies show that the average person gets only about 1200 ORAC units per day from 3 servings of fruits and vegetables.
However 3,000 to 5,000 ORAC units per day are required to have a significant impact on plasma and tissue antioxidant capacity.
The antioxidant value of Goji berries described in ORAC units is 25300 μ mol TE/100g.
The ORAC value is expressed in micromoles of Trolox Equivalents per 100 grams of sample (this is the laboratory measure of ORAC)
