Lutein is a type of organic pigment called a carotenoid. It is related to beta-carotene and vitamin A. Many people think of lutein as "the eye vitamin."
Lutein is one of two major carotenoids found in the human eye (macula and retina). It is thought to function as a light filter, protecting the eye tissues from sunlight damage. Foods rich in lutein include egg yolks, spinach, kale, corn, orange pepper, kiwi fruit, grapes, zucchini, and squash.
Lutein is commonly taken by mouth to prevent eye diseases, including cataracts and a disease that leads to vision loss in older adults (age-related macular degeneration or AMD). Lutein is used for many other conditions, but there is no good scientific evidence to support these other uses.
- Age-related macular degeneration (AMD).  When used alone or in combination with other ingredients, oral lutein seems to improve some aspects of vision in patient with AMD. However, it does not seem to slow the progression of AMD.

Lutein is found in many foods, including egg yolks, spinach, kale, corn, orange pepper, kiwi fruit, grapes, zucchini, and squash. There's 44 mg of lutein in one cup of cooked kale, 26 mg per cup of cooked spinach, and 3 mg per cup of broccoli.
Lutein is also taken in supplements. It's most often been used by adults in doses of 10-20 mg by mouth daily, for up to 3 years. Many multivitamins contain lutein. They usually provide a relatively small amount, such as 0.25 mg per tablet. Lutein is absorbed best when it's taken with a high-fat meal.
