Zeaxanthin a carotenoid found in various fruits and vegetables such as spinach. Zeaxanthin is not synthesised in the body and is, therefore, a diet-obtained carotenoid, hence eating foods rich in Zeaxanthin and Lutein or taking supplements is important. Supplementing Zeaxanthin or getting it through your diet helps promote and maintain good eye heath. Recent studies indicate that there are traces of Zeaxanthin in the macula region of the eye.
Therefore, it plays a significant role in good vision and eye health. Zeaxanthin is a potent fat-soluble antioxidant with great benefits to the eye. Carotenoids have a yellow appearance. Zeaxanthin can also be found in green leafy vegetables such as spinach, broccoli and kale and other foods such as egg yolk.
Due to its antioxidant properties, Zeaxanthin can neutralize unstable molecules (free radicals) that might otherwise cause oxidative stress or retina damage. Therefore, Zeaxanthin plays a significant role in decreasing the risk of contract formation which clouds the natural lens in the eye.
Zeaxanthin and lutein also filter harmful high energy light waves such as blue wavelengths and ultraviolet light hence protecting and maintaining healthy cells. The amount of Zeaxanthin in the macula region of the retina is measured as MPOD (macular pigment optical density). Recently, high levels of MPOD are linked with better vision function especially in dim light or when glare is challenging and the prevention of eye diseases.
Ci sono molte prove che la zeaxantina e la luteina riducono il rischio di malattie degli occhi legate all'età e di una degenerazione maculare lenta che danneggia il centro della retina e potrebbe portare via la visione centrale dell'occhio.
