Bilberry extract comes from the small, dark-blue berries of the Vaccinium myrtillus plant, which are naturally rich in anthocyanins—the same plant pigments that give blueberries their color. These compounds are valued in supplements for their antioxidant properties and are a key reason why bilberry has been part of traditional European herbal practices for centuries.
