Help promote healthy eyesight with Lutein.
Don’t forget to finish your spinach next time you sit down at the dinner table. Spinach, kale, garden peas and other dark green, leafy vegetables contain a naturally-occurring carotenoid (or pigment) called lutein which protects the eyes from harmful light rays. Lutein is also found in zucchini, pistachio nuts, brussels sprouts, yellow corn, kiwi fruit, and egg yolks however the dark leafy vegetables contain the richest source.
Lutein filters out the blue light rays present in sunlight and indoor lighting. Unlike invisible Ultraviolet A (UVA) or Ultraviolet B (UVB) rays, blue light is visible. Scientists believe that blue light plays a key role in age-related degenerative damage by producing harmful free radicals in eyes and skin, the only exposed areas of the body.
Concentrated in the macula, the portion of the retina governing central vision, lutein shields the eyes from the harmful effects of high-energy blue light rays. Lutein can filter up to 90% of blue light rays and thereby help to prevent the degenerative damage to eyes caused by free radicals.
Research has shown a direct relationship between lutein consumption and protective pigments in the eyes. Studies also indicate that increased pigmentation in the macula reduces the risk of eye-related diseases like age-related macula degeneration (AMD). Research findings further suggest that a combination of lutein and other nutrients may even more effective against blue light and free radical damage.
Epidemiological evidence supports a relationship between low levels of lutein and zeaxanthin and an elevated risk for AMD. Research suggests that macular degeneration vitamins containing a mix of lutein and zeaxanthin are the most effective in heading off AMD and protecting against blindness.
There’s also evidence that increasing lutein and zeaxanthin intake protects eyes from the formation of cataracts. In addition, subjects treated with daily doses of 10 mg of lutein and 2 mg of zeaxanthin show decreased sensitivity to light and improved visual performance.
Studies have found that a minimum intake of 6-10 mg/day of lutein is required to maintain optimal concentrations of this nutrient in the blood. The problem is that even with regular nutritional meals, one would still need to consume a large bowl of spinach every day in order to ingest enough lutein to benefit from it’s protective influence. Because many patients are deficient in lutein, macular degeneration vitamins may offer them the most effective preventative macular degeneration treatment.
Although there are a number of macular degeneration treatment supplements on the market today, Macuhealth with LMZ3 is the only carotenoid supplement with a formulation that combines protective lutein with the key ingredient of meso-zeaxanthin.
There are no known adverse interactions between lutein, zeaxanthin, and other medications, but consulting a physician prior to adding a regiment of macular degeneration vitamins to the diet is highly recommended.
