Cranberry juice is the liquid juice of the cranberry – a fruit recognized for its bright red color, tart taste, and versatility for product manufacturing. Major cranberry products include cranberry juice, dried cranberry, cranberry sauce, frozen cranberry, cranberry powder, and dietary supplements containing cranberry extracts. Cranberry juice may help prevent infections, delay or reduce the severity of chronic disease, and prevent age-related oxidative damage. For most healthy people, cranberry juice is safe, but it can interact with certain drugs.
