The answer is simple: eat fish (preferably oily fish) at least twice a week. Although we can certainly tell you which fish oil supplements (or other omega-3 supplements) are best for providing EPA and/or DHA
, our analyses of the clinical literature show that, for both age-related macular degeneration (AMD) and Alzheimer's disease, supplements have generally not
been beneficial, while regular consumption of fish is associated with benefits. Only if you won't or can't eat fish at least twice a week might
fish oil supplements be helpful for these conditions.

and Eye Disease
sections of the Fish Oil and Omega-3 Supplements Review.
