Carotenoid that Provides Major Protection Life Blend's Vision Support is Formulated around the main ingredient, Lutein, known as The Eye Vitamin. Lutein has been shown to support visual function and to protect the health of eye tissues as we age.The typical western diet doesn't includeLutein is a carotenoid found in tomatoes, mangos, sweet potatoes, leafy greens, and carrots. The typical western diet doesn't include nearly enough of these fruits and vegetables - so it's likely you have a deficiency in lutein.Supports age-related eye challengesStudies have shown that lutein promotes eye and vision help and combat age-related eye challenges. Lutein helps the pigment of your retina which absorbs harmful light - acting as a sort of filter. You were born with a certain amount of lutein in your eyes, but your body does not reproduce it. You must get lutein from your diet and supplementation.Provide protection against oxidative and free radical damageOne of the primary functions of lutein is to provide protection against oxidative and free radical damage. These yellow-colored carotenoids are found in high concentrations within the macula lutea (the yellow spot in the center of the retina) and in smaller amounts throughout the retina and the eye lens. They are also present in the skin, breast and cervical tissues. These stores, however, appear to diminish with age if not regularly replenished through dietary means.Protected from light-induced damageScientists believe that lutein contribute to the density of macular pigment--the component of the eye which typically absorbs and filters out 40 to 60 percent of damaging near-ultraviolet blue light, which strikes the retina. Lutein also helps limit blue light damage to the inner retina by protecting against lipid peroxidation and by neutralizing free radicals.
