Can fish oil improve my vision?

Don't Know: Omega 3 fatty acids are suspected to improve patients with macular degeneration. This has yet to be proven, but a study is underway to determine this exact question. Look for data from the "areds 2" study due to come out in the 1-2 years. The short answer is that nothing has been proven.

Hype: Krill oil and fish oil are the new snake oil, both are high in omega 3 fatty acids which are extremely fragile. Omega 3 fish oils reduce triglycerides by impairing the liver's ablility to make them. However the oxidative stress caused by fish oil actually raises LDL cholesterol. Some day we may use the phrase "this is just more fish /krill oil" or "here comes the fish/krill oil salesman".

Maybe: There is study data suggesting that people who eat fish twice per week are less likely to get macular degeneration. Right now, fish oil is being evaluated for this purpose. Fish oil is known to lower cholesterol and lower this risk of heart attack. Eat fish - it's good for you.
