Black elderberries have an extremely high concentration of certain flavonoids called anthocyanins which are responsible for the berry’s signature deep purple color. Anthocyanins are powerful antioxidants that work within the immune system to enhance the body’s response and keep it functioning at its best. Black elderberries have nearly double the amount of anthocyanins found in any other fruit, which gives black elderberries twice the natural antioxidant capacity of blueberries and significantly more than cranberries. Sambucol's unique manufacturing process harnesses the natural power of these anthocyanins, providing a health supplement suitable for the whole family.
