O'Halloran, Ph.D., from Trinity College in Dublin, and colleagues evaluated the association between three frailty instruments (the Frailty Phenotype, the Frailty Index, and the FRAIL Scale) and circulating micronutrients (lutein, zeaxanthin
, folate, vitamin B-12, and vitamin D) in a large representative sample of 4,068 adults (age ≥50 years) living in the community in Ireland.
Vitamin E, lutein, beta carotene and zeaxanthin
are the components of paprika that are known to promote healthy vision.
Lutein and its "partner" carotenoid, zeaxanthin
, are the only antioxidants located in the eye.
These antioxidants are lutein and zeaxanthin
. Lutein is a deep yellow pigment found in the leaves of plants, and zeaxanthin
a carotenoid found in the retina of the eye and in many plants like spinach.
"Eggs are rich in lutein and zeaxanthin
nutrients, helping reduce age-related macular degeneration," says Menon.
Two of those pigments are carotenoids called lutein and zeaxanthin
Researchers have linked eye-friendly nutrients, such as lutein and zeaxanthin
, vitamin C, vitamin E and zinc, to reducing the risk of certain eye diseases.
The dietary consumption of dark green leafy vegetables or supplements that contain specific carotenoids known as Lutein and Zeaxanthin
are believed to possess the ability to prevent and/or slow the progression of Age-Related Macular Degeneration.
The AREDS 2 formula provides daily 10 mg of lutein and 2 mg of zeaxanthin
. Both groups had significant improvements in contrast sensitivity at six cycles per degree (the primary outcome measure), in other measures of contrast sensitivity and visual function, and in the amount of macular pigment.
Lutein and the zeaxanthin
isomers (RR-zeaxanthin and RS [meso]-zeaxanthin) are found in high concentration in the macula--a region of the eye that provides the highest visual acuity and is also exposed to high levels of blue light.
ZMC is the worldwide leader in the development and manufacture of nutritional ingredients including Coenzyme Q10, Vitamins A and E, Beta Carotene, Lutein, Biotin, Zeaxanthin
, Lycopene, and Astaxanthin.
Carotenoids, especially lutein and zeaxanthin
, are functional pigments that are present in many kinds of plants, animals, and microorganisms .
