It's all about the Color Red  We freshly squeeze Star Ruby Grapefruit into our 100% Florida Grapefruit Juice. This special red grapefruit has the most vibrant red color and luscious flavor of any grapefruit in the world! The deep red color not only offers mouth watering juice, it guarantees the highest level of antioxidants in any grapefruit. Many researchers believe that powerful antioxidents such as Vitamin C, Lycopene, and Phytonutrients found in grapefruit juice may help the body in its battle against infection, cancer, ulcers, and heart disease.
