Lutein

Lutein dipalmitate is derived from the perennial plant Helenium autumnale L. Compositae. It is a member of the carotenoid family. Carotenoids are naturally occurring fat-soluble pigments found in algae, certain plant species, and photosynthetic bacteria. These yellowish pigments protect organisms from the harmful, and often times, toxic effects of ultraviolet radiation and oxygen. Carotenoids are a classification of nutrients popularized by the antioxidative properties of Beta-Carotene in the early 80s.


There are over 600 different carotenoids found in nature, and only a percentage of this number is found in serum levels throughout the human body. Of this minute percentage, only lutein and zeaxanthin exist within the macula of the eye. This suggests that that these two nutrients provide for critical roles in eye health. The macula of the eye is directly responsible for central vision and visual acuity. Lutein and zeaxanthin alone, are responsible for the eye's development of macular pigment (MP) within the macula. [2, 3] The formation of MP is critical in the protection of the macula from photo-oxidation. Damage caused by oxidative stress within the retina can lead to the deterioration of the macula, potential causing age-related macular degeneration (AMD) and other visual disturbances.


Lutein
is included in a separate class of carotenoids named xanthophylls. Xanthophyll carotenoids include lutein, alpha-and beta-crptoxanthin, and zeaxanthin. They deviate from the standard carotenoid by the inclusion of a hydroxyl group upon their chemical structures. This added hydroxyl group gives xanthophylls, like lutein, an increased polarity, thus enabling them to carry/contain oxygen. Because of this, xanthophyll carotenoids are also referenced as oxycarotenoids. This characteristic affords xanthophylls the added protection and stability from pro-oxidants. This is extremely beneficial in human physiology as both free radicals and pro-oxidants contribute to the destruction of cellular structures.


Lutein
also has a higher bioavailability than beta-carotene; fatty foods may enhance its absorption percentage. Upon its ingestion, lutein is primarily accumulated in the macula of the retina where it will then bind itself to tuberlin, a retinal protein of the eye. Smaller amounts of lutein may also be deposited in the skin, and the breast and cervical tissues of females.
