Quick answer: In AREDS2, adding 10 mg lutein and 2 mg zeaxanthin to an eye vitamin formula helped people with intermediate macular degeneration, and they safely replaced beta-carotene, which raised lung cancer risk in former smokers.
What AREDS2 tested
The US National Eye Institute studied about 4,000 people at risk of advanced age-related macular degeneration.
Key findings
- The formula slowed progression to advanced AMD in people who already had intermediate AMD.
- Lutein and zeaxanthin worked as a safer replacement for beta-carotene.
- There was no clear benefit for people without AMD.
Food sources
