Is Your Eyesight Worth Protecting?

Posted June 27, 2017

Many of us try to eat a variety of foods, like fruits and vegetables, to stay healthy. By now we’ve heard how the antioxidants in these foods can serve to block damaging molecules in our bodies. But did you know that two antioxidants, lutein and zeaxanthin, are the ONLY antioxidants deposited by our bodies, specifically into the retina of our eyes, to help filter blue light? 1,2 Everyone is exposed to blue light, a component of sunlight, which can potentially damage our eye’s retina. 3,4

For Healthy Vision Month, it’s time to look at how much lutein and zeaxanthin you need to eat - as recommended by the National Eye Institute, part of the National Institutes of Health, in their landmark study known as AREDS2 (Age Related Eye Disease Study 2). 5 The most compelling finding from the AREDS2 study was that the people who benefited most from lutein and zeaxanthin supplementation were those who had the lowest dietary intakes of lutein and zeaxanthin. In the group with the lowest dietary intake, supplementation with lutein and zeaxanthin reduced the risk of progression to advanced age-related macular degeneration (AMD), the number one cause of blindness in adults, by 26 percent above and beyond the effects of the AREDS1 supplement formula.

AREDS2 proved that 10 mg of FloraGLO® lutein and 2 mg of zeaxanthin, in conjunction with the original AREDS1 formula:

  • Lowered the risk of progression for eye disease in an at-risk population further than the AREDS1 formula alone
  • Supported the replacement of beta-carotene with lutein and zeaxanthin to improve both the safety and efficacy of AREDS formulations. 5,6

How Much Lutein Should You Eat? 7


Label Lingo

The source of lutein matters. Look for FloraGLO® Lutein on the label and you’ll know you are buying the number one eye doctor recommended brand, with 80 clinical trial publications supporting it. 8,9 No other lutein brand is more researched. 9 FloraGLO is the brand covered by a blue light patent to protect eyes most vulnerable to damage. 10 The recommended level for vision health is 10 mg of FloraGLO Lutein and 2 mg ZeaONE® / OPTISHARP® Natural Zeaxanthin.

Natural Source of Antioxidants

FloraGLO contains lutein and zeaxanthin that is found naturally in foods. A third eye antioxidant, meso-zeaxanthin (or RS-zeaxanthin) is found in the eye but not in the typical human diet. 11 Meso-zeaxanthin is made from lutein through conversion within the human body. 12 No studies (human or animal) have been published evaluating the safety or efficacy of meso-zeaxanthin alone (without the presence of lutein and zeaxanthin) .
