Blueberry fruit has good nutritional value and health benefits. The Food and Agriculture Organization of the United Nations lists it as one of the five health foods for humans.
In addition to conventional nutrients, blueberry extract powder also contains anthocyanins, superoxide dismutase, flavonoids, ellagic acid and other ingredients.
Studies have found that the content of anthocyanins in different varieties of blueberries is not the same, but generally high. The National Human Nutrition Center (NHRCA) of the United States Department of Agriculture (USDA) tested 41 kinds of fruits and vegetables and found that blueberries have the highest antioxidant activity and are called the "first antioxidant."
