Clinical Grade Lutein Is the Single Most Important Nutrient for Your Eyes
When it comes to supplements for eye health, I simply cannot overstate the importance of lutein. My Clinical Grade Lutein—with 20 mg of lutein and 4 mg of naturally occurring zeaxanthin—provides just what you need for premier eye health. Lutein, the single most important carotenoid for your eyes, has been clinically studied to support the health of the macula, support vision under low light conditions, and protect your eyes against oxidative stress caused by harmful blue light.
Just one daily softgel of the optimal, clinically studied dosage in Clinical Grade Lutein: Promotes and protects the overall health of your eyes Supports macular health and visual performance Helps with light adaptation in low light conditions Protects eyes from oxidative stress
Plus, you can double the dose for even more eye health benefits!
Zeaxanthin helps maintain lens health
Zeaxanthin is critical, too, as it helps maintain the health of your lenses, photoreceptors, and retinal lining. Similar to lutein, zeaxanthin concentrations in the macula area of the retina naturally decline as you age. But since your body can’t produce it, it’s important to supplement with optimal amounts. With Clinical Grade Lutein you get 4 mg of naturally occurring zeaxanthin.

One of the world’s most beneficial nutrients for overall eye health, lutein has been shown in dozens of studies (in multiple dosages) to effectively shield the retina, lens, and macula from free-radical damage caused by years of exposure to oxygen and light. A healthy retina and macula are vital for seeing clear, sharp images and perceiving colors. Unfortunately, the amount of lutein in your eyes naturally declines with age. This is why supplementing with lutein is important for maintaining the health of your eyes and helping you keep your independence.
Research: 20 mg of lutein increases MPOD—improves contrast and glare sensitivity
In a one-year randomized, double-blind, placebo-controlled study, participants received 20 mg of lutein once daily or a placebo. The group receiving lutein experienced a significant increase in macular pigment optical density (MPOD) in as little as 6 months and again at 12 months, and improvements in contrast and glare sensitivity, especially in high and low light conditions. Having a higher MPOD is an important measurement of eye health as macular pigment plays a critical role in protecting the macula from harmful blue light and maintaining crisp, detailed, colorful vision.
Additionally, the study showed improved bioavailability of lutein in the eye in as little as one month. (Measurements were taken at four different locations in the eye since cell density is unequal throughout the eye.) Furthermore, there were significant improvements in scores on the National Eye Institute 25-Item Visual Functioning Questionnaire. Overall the study shows improved eye health benefits for those supplementing with 20 mg of lutein daily.1
Two more studies on improved glare tolerance and macular health
In another study, adults who took 10 mg of lutein and 2 mg of zeaxanthin daily had significant improvements in the concentration of protective carotenoids in the macula of the eyes, as well as macular pigment ocular density (MPOD), glare tolerance, and other aspects of vision health. Specifically, MPOD levels improved and individuals were able to tolerate more intense glaring light.2 Overall, the study showed that lutein and zeaxanthin improve the ability to adjust to glare and contrast while helping support visual acuity.
And in a two-year randomized study with patients age 50 and over, supplementing with either 10 or 20 mg a day of lutein improved macular health by increasing the retinal sensitivity (the ability to adapt to light) and increasing macular pigment density.3
I’ve long been a proponent of proactively fortifying your eyes with the right nutrients, and supplementation is key. Over 20 years ago, when I first began encouraging my patients to take lutein, the naysayers called me nuts. Back then, supplementation for the eyes simply wasn’t on the radar of most eye doctors, let alone MDs. Here we are two decades later and vision supplements are everywhere. But only a select few offer the premium quality and clinically studied dosage that Clinical Grade Lutein provides.
