Should I take an AREDS Formula with Lutein?
Lutein has been shown to improve visual sharpness in patients with AMD, according to the LAST trial (Lutein Antioxidant Supplementation Trial).1 AREDS research found that lutein absorbs blue light that could damage the macula. This absorption could prevent free radicals from damaging eye cells while strengthening eye cell membranes.2 This study concluded that long-term lutein intake may lower the risk of developing AMD. Most studies recommend 6-10 mg of lutein daily.
What is Lutein?
Lutein is a carotenoid found to be highly concentrated in the macula, a small area of the retina responsible for central vision, and high visual acuity. Lutein can be found in foods such as egg yolks and dark, leafy vegetables. Approximately half of Americans only get 1-2 mg each day from their diet - a fraction of the amount needed to replenish levels in the eye. Lutein cannot be made by the body and therefore must be obtained from food or dietary supplements.
Why wasn't lutein included in the original AREDS study?
Lutein was not available when AREDS was started, but it is apart of the AREDS 2 study that is currently in process. The AREDS 2 study explores the help of lutein, zeaxanthin, and omega-3 and AMD.
Viteyes® offers a variety of AREDS formulas with lutein. If you are a smoker or former smoker try one of the Viteyes® formulas without beta-carotene.
