Zeaxanthin and lutein are foundational nutrients essential in protecting and enhancing vision. Zeaxanthin is a carotenoid, which is another word for antioxidant, found in the retina, blood serum, and brain. Zeaxanthin is chosen by the retina to protect central vision. Lutein is another carotenoid that is found in the brain and eyes as well as breast milk and works in conjunction with zeaxanthin but protects peripheral vision.
Even though you may generally be healthy and eat better than the average American, the most important eye-healthy nutrients, zeaxanthin and lutein, are notably scarce in food sources. Even if you eat your share of leafy greens and colorful vegetables, you need to eat 20 ears of corn a day to get the amount of zeaxanthin your eyes need. That's where supplementation comes in.
This critical antioxidant is chosen by the retina to protect central vision. Additionally, zeaxanthin is accumulated in the fovea (center of the retina) 2 times more than lutein. While the eye itself chooses to include more zeaxanthin in its own protection, most eye vitamins choose to match the ratio found in the diet, which is 5 to 1 lutein to zeaxanthin. EyePromise recongnizes the importance and scarcity of zeaxanthin and, therefore, chooses to include 4x more than other products.
While zeaxanthin is extremely important, lutein is no scrub. This antioxidant plays an important role in protecting vision from dangerous blue light, and it's been found to help support many other parts of the body.
