Lutein, zeaxanthin and omega-3 help those with AMD
by Newsletter Editor
Age-related macular degeneration (AMD) is the progressive loss of sight in the center of the field of vision, the most common form of blindness. To filter the harmful light that can trigger AMD, the eye requires the carotenoid pigments lutein and zeaxanthin.
In this study, 145 people with dry AMD, where the layer of pigment in the eye has thinned, took a placebo or a combination of lutein, zeaxanthin, and omega-3. There were two doses: 10 mg of lutein, 1 mg of zeaxanthin, 100 mg of DHA, and 30 mg of EPA with antioxidants; or double these doses.
After 12 months, while there were no changes for placebo, both lutein / zeaxanthin / omega-3 groups had similar increases in the density of the pigment layer of the eye, with benefits beginning at one month and continuing throughout the study.
