Sambucol products contain black elderberry extract in their potent formulas. Black elderberries are one of the best antioxidant foods and contain double the amount of antioxidants found in blueberries. Antioxidants support the immune system by protecting against free radical damage. The supplement is developed through a unique manufacturing process, which ensures that the powerful activity of the flavonoids (a type of antioxidant) is retained.
