Consuming corn, dark leafy greens, or egg yolks (amongst various other natural sources) can provide our body with substantial sources of “the eye vitamin” – lutein.
Lutein is a carotenoid vitamin that supports the body to prevent eye diseases related to aging, particularly cataract and macular degeneration.
Role of lutein in the human body
The human body uses lutein, in general, as an antioxidant and, in particular in the eye, for the absorption of blue light.
A natural concentration of lutein is found in the human eye – in the macula, an area of the eye’s retina. Scientists believe that lutein keeps the eye safe from oxidative stress and the high-energy photons of blue light (like those in fluorescent lights).
A diet that is lutein-rich is found to support the prevention of cataracts and to improve vision over time for those with cataracts. Lutein is found to reduce the risk of age-related macular degeneration (AMD). A large government study confirmed that lutein reduces the progression of a chronic eye diseases.
As an antioxidant and anti-inflammatory agent, lutein supports optimal brain function and is the predominant carotenoid in human brain tissue. New research is exploring how higher lutein levels relate to better cognitive performance.
High intake of antioxidants, like lutein, can help combat free radical damage, which may otherwise lead to disease and various forms of cancer. Scientists have found positive results in testing the impact of lutein on cancers, both to reduce existing tumors and to prevent tumor growth.
Healthy sources of Lutein
Lutein can be found in leafy greens, like spinach and kale, and in vegetables, like yellow carrots. The old saying that “eating carrots will help you see in the dark” comes to mind!

The lutein in our Brain & Vision Formula is sourced from the petals of marigolds! Marigolds, or calendula officinalis, are grown, harvested, dried, and then processed to extract and purify abundant amounts of lutein.
