Macular degeneration is a progressive eye condition that has no cure. In some cases, a specific combination of nutrients found in supplements called AREDS 2 can slow its progression.
Age-related macular degeneration (AMD) is an eye condition that damages the macula, the part of your eye that plays a role in your central (straight-ahead) vision.
There are different types of AMD: dry AMD and wet AMD.
Dry AMD is more common. In dry AMD, age, genetics, and certain lifestyle factors cause the cells of the macula to break down. There’s also a buildup of proteins called drusen.
Wet AMD develops from leaking blood vessels in the eye, causing fluid buildup around the macula.
Yes. According to the Age-Related Eye Disease Studies (AREDS/AREDS 2)Trusted Source, certain supplements may help slow AMD progression for some people.
However, AREDS 2 supplements may not be helpful for all stages of AMD. That’s why it’s important to talk with your eye doctor to find out whether AREDS 2 supplements could be part of your AMD management plan.
AREDS vs. AREDS 2
The original AREDS clinical trial used a slightly different combination of nutrients. AREDS 2 is the most recent formulation and is more widely used now.
The biggest difference is that the original AREDS contains 15 milligrams (mg) of beta carotene. In the AREDS 2 trial, beta carotene was replaced with lutein and zeaxanthin.
Beta carotene can increase lung cancer risk for current or former smokers. The new formula is safe for smokers and nonsmokers alike.
