Vitamin C and bioflavonoids are important antioxidants that help keep your eyes and body healthy. Foods high in vitamin C, such as citrus fruits and many vegetables, are also excellent sources of bioflavonoids. Research suggests vitamin C and bioflavonoids have a complementary effect, making them both more effective when ingested together rather than separately.
Vitamin C (also known as ascorbic acid) is a water-soluble vitamin and a powerful antioxidant. Abundant in fruits and vegetables, vitamin C helps the body form and maintain connective tissue, including collagen found in the cornea of the eye. Vitamin C also promotes healthy bones, skin and blood vessels, including the delicate capillaries in the retina. Studies suggest long-term consumption of vitamin C also may reduce the risk of forming a cataract and vision loss from macular degeneration.
