PreserVision 3 is a food supplement for eye purposes. It is a product rich in vitamins C and E, and Zinc, which are nutrients with antioxidant properties. It also contains pigments of the carotenoid family (lutein and zeaxanthin) and omega-3 fatty acids.
Antioxidants (vitamins C, E and zinc) protect cells against free radicals. Lutein and zeaxanthin are pigments that are naturally found in the retina. The body cannot manufacture them and must obtain them through food. The eye is particularly rich in omega 3, specifically in DHA which is important for visual function.
