Lutein and Zeaxanthin May Reduce Macular Degeneration Risk in Older Adults
Taking lutein and zeaxanthin supplements may reduce the risk of advanced age-related macular degeneration in older adults.
Summary
In plain language
Recent research suggests that adding lutein and zeaxanthin to daily supplements might help lower the risk of progressing to advanced age-related macular degeneration (AMD) in seniors. This study followed participants over ten years and found that those taking these supplements had a lower chance of developing severe AMD, compared to those who took beta-carotene, which was linked to a higher risk of lung cancer, especially in former smokers. The findings are important because AMD is a common cause of vision loss in older adults. Seniors should consider discussing with their healthcare providers whether these supplements could be beneficial for them.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study followed participants from the AREDS2 trial over a decade to understand the effects of different supplements on eye health.
Participants were randomly assigned supplements including lutein/zeaxanthin or beta-carotene and followed for ten years.
Results showed that lutein/zeaxanthin was associated with a reduced risk of advanced AMD, while beta-carotene increased lung cancer risk, especially in former smokers.
The study highlighted the importance of choosing the right supplements for eye health, but noted limitations such as self-reported data and the study's observational nature.
Seniors should talk to their doctors about whether lutein and zeaxanthin could be a safe and effective option for maintaining eye health.
