Lutein is a member of the carotenoid family that works with a steroisomer, zeaxanthin. They are both natural, fat-soluble, yellow pigments found in some plants and algae. Lutein and zeaxanthin are both naturally present in the retina and macula (eye) as well. Lutein and zeaxanthin work to gather and reflect lights, protecting organisms from harmful UVs and oxygen. These are the only two carotenoids found in the human lens that work to protect against cataract development and increases in lens density. Lutein can be found abundantly in corn, egg yolks, green vegetables and fruits. Lutein demonstrates antioxidant qualities as well.
The absorption and effectiveness of lutein may be decreased when combined with cholestyramine, colestipol, orlistat, or beta-carotene.
At the time, there have been no reported side effects from the use of lutein. Please take in the recommended dosage.
