Nowhere in the human body is the nutritional significance of carotenoids more apparent than in the retina. Meso-zeaxanthin, a naturally occurring carotenoid, is the central yellow pigment found in the posterior segment of the eye. The same pigment contains two other vital carotenoids called lutein and zeaxanthin; both of which are crucial in helping protect the macula from oxidative stress and filtering harmful blue wavelength light. However, while it is clear that all three of these carotenoids could be considered fundamental, recent research has proven that the role of meso-zeaxanthin is likely even more important when it comes to slowing AMD. 1
“What we have seen is that you can increase your macular pigment level uniquely, efficiently and at a very high level if you have meso-zeaxanthin in the formulation,” confirms Dr. John Nolan, principle investigator of the Macular Pigment Research Group at Waterford Institute.2
Though it is possible to include lutein and zeaxanthin in your diet via yellow and green leafy vegetables such as kale and corn, meso-zeaxanthin is much more difficult to acquire.
Meso-Zeaxanthin can be converted from lutein in the center of the eye and becomes an especially supportive antioxidant. Unfortunately, this nutrient is not found in a standard North American diet. Plus, some people, particularly older individuals, have enzyme deficiencies that actually prevent lutein from forming into MZ. So, how can you obtain this necessary carotenoid?
A supplement that contains meso-zeaxanthin can ensure that eyes get a good dose of this wonder-antioxidant in its converted form. Receiving meso-z in its converted form is crucial for those who lack the ability to convert lutein to MZ naturally. Obtaining MZ through a daily supplement is truly the only practical means of getting a proper dose.
“As we move into an ageing society, supplementation [is] key,” explains Dr. Nolan. “Sixty is not old anymore, but at 60 you are at high risk of developing macular degeneration and losing central vision, so we have to optimize nutrition in these individuals,”2 he adds.
It’s been observed that lutein, zeaxanthin and meso-zeaxanthin are extremely powerful free radical neutralizers. Together, they can slow the progression of AMD. MacuHealth is a supplement that combines these three carotenoids to enrich an individual’s protective macular pigment. AMD patients should consider taking once daily MacuHealth in order to compensate for low levels of meso-zeaxanthin.
Promote a healthy macula; it’s never too late to start taking MacuHealth.
What measures have you taken to ensure you get your dose of meso-zeaxanthin?
