Blood oranges are a variety of sweet orange (Citrus × sinensis) distinguished by their deep crimson to burgundy flesh, which develops from the natural production of anthocyanins—the same antioxidant pigments found in blueberries, cherries, and blackberries. Their flavor is sweeter and more complex than that of traditional oranges, with subtle notes of raspberry and cherry balanced by bright citrus acidity.

Like other citrus fruits, blood oranges are an excellent source of vitamin C, but their rich anthocyanin content provides an additional layer of antioxidant protection not found in most orange varieties. They also provide fiber, potassium, folate, and a variety of citrus flavonoids that work together to support cardiovascular health, immune resilience, skin health, and overall wellness.
