Lutein Benefits

Lutein is supposedly useful for a variety of uses. Some of the potential benefits of lutein include treating and preventing several eye problems (such as macular degeneration and cataracts), preventing diabetes, and preventing cancer. However, many of the claimed benefits were found through studies that looked at obtaining this substance through dietary means rather than with supplementation.

Possible Benefits of Lutein

Lutein is claimed to be beneficial for a few different purposes. Some of these uses include:
People usually associate lutein with benefits for the eyes, and some of the major "eye vitamin" products available contain it. Many multivitamins also now contain a low dose of lutein, although it is thought that this amount is probably too low to truly be beneficial.
It is important to understand that many of the claimed lutein benefits were found in studies that looked at a high intake of lutein through the diet, not through supplementation. Supplementation might not be as effective as increasing lutein intake through the diet by eating more fruits and vegetables.

Why Is Lutein Beneficial?

Lutein is one of two carotenoids found in the retina and macula of the human eye. Carotenoids are yellow, red, orange, and purple pigments found in most living things. The substance is believed to act as an antioxidant and a filter for blue light, helping to protect the eye tissues from sun damage. Lutein is also found in the bloodstream and in fat deposits.
