Research indicates that absorbing high amounts of lutein does not lower the risk of developing clogged arteries, states WebMD. The site classifies the vitamin as “possibly ineffective” for treating clogged arteries or coronary heart disease.
Lutein is one of the two primary carotenoids located in the color pigment of the human eye and works as a filter to protect eye tissues from light exposure, according to WebMD. This has earned the vitamin the nickname “the eye vitamin.” This supplement is typically used to treat a lutein deficiency or to improve the symptoms of an eye condition known as age-related macular degeneration. Many also take the vitamin to decrease the risk of developing cataracts and to improve vision already distorted by cataracts.
