Fresh blueberries sold in a 2-pound (907g) package, sourced for Costco's produce section. Blueberries are widely celebrated as a nutrient-dense superfood, prized for their high concentration of antioxidants, particularly anthocyanins, which give them their characteristic deep blue-purple color and are associated with brain health and immune support.

These berries can be enjoyed in countless ways: eaten fresh by the handful, added to yogurt, oatmeal, or cereal, blended into smoothies, or used in baking for muffins, pancakes, pies, and cobblers. Any extras can be frozen flat on a sheet pan and stored for months, making the bulk Costco size a practical choice for families who use blueberries regularly. When buying, look for firm, plump berries with a silvery-white bloom on the skin—a sign of freshness.
