Lutein – Zeaxanthin

Antioxidants | Eye Health |

Lutein and zeaxanthin are carotenoids (xanthophylls), very common in many species of plant realm and greatly abundant in green leafy vegetables, stored in plant tissues with the function of light quenchers. Moreover lutein and zeaxanthin are accumulated in humans’ eyes (particularly in the macula lutea in the retina) and work as a protection shield against blue light radiations, especially dangerous for this tissue. These are also molecules with a proven antioxidant activity.

Supplementation of these carotenoids has been proven beneficial for improving acuity of the vision and preventing age-related macular degeneration.

For both carotenoids many different formulations at various concentrations are available: oils (i.e. safflower, sunflower), powders and microcapsules; micro-encapsulation process can be performed with several different types of gelatins and insures better technical properties (i.e. flowability) and that carotenoids are safely protected from oxidation, temperature and moisture, thus increasing shelf life and quality of the product.
