Omega-3 Plus AREDS Vitamins Reduce AMD Risks
Researchers from Tufts University, the University of Wisconsin, and The EMMES Corporation found high intakes of
omega-3 fatty acids, DHA and EPA, and vitamins reduce the risk of Age-related Macular Degeneration (AMD).
High intake of DHA as associated with a 27 per cent reduction in the progression to AMD. High EPA intake was
associated with a 26 per cent reduction of AMD.
AMD is a degenerative retinal disease that causes central vision loss and leaves only peripheral vision and is the
leading cause of legal blindness for people over 55 years on age in the Western world.
The vitamin formula used in this study was the AREDS formula sold by Bausch and Lomb. The AREDS formula contains
vitamins C, E, beta carotene, zinc and copper. A newer version AREDS2 will include the antioxidant carotoinoids
lutein and zeaxanthin and the omega-3 fatty acids DHA and EPA.
Researchers analysed dietary information from 2,924 participants. The highest average intake of DHA of over 64 mg
per day were associated with a 27 per cent reduction in advanced AMD, compared with intakes less than 25 grams per
day. EPA intakes over 42.3 mg per day were associated with a 26 per cent reduction, compared to intake of less than
12.7 mg per day.
DHA and EPA dietary supplements were not evaluated.
