Feb 24, 2026Vision and Age-Related Macular Degeneration: Lutein, Zeaxanthin, and AREDS2 EvidenceThe AREDS2 trial established lutein and zeaxanthin as replacements for beta-carotene in the AMD supplement formula, reducing progression risk by 25% in high-risk eyes. Dietary intake from dark leafy greens provides equivalent carotenoids. This article explains what the evidence supports and what it does not.
Feb 3, 2026Eye Health and Macular Degeneration Prevention: AREDS2 Formula, Lutein, and ZeaxanthinAge-related macular degeneration (AMD) is the leading cause of vision loss in older adults.
