Where they differ

From the rows
Study designWhen published

The best-graded row, grade A, is a meta-analysis of 3,189 people (2021) and found an improvement. 1 row is graded No effect, our grade for adequately powered trials that found no effect.

Only the 3 rows that found an improvement include pooled reviews of several trials (1 of 3); the row that found no difference is a single study.

The 3 rows that found an improvement are newer (2021 to 2025) than the row that found no difference (2013).

  1. Grade AMacular pigment optical density · Improved

    Meta-analysis, 46 studies · n 3,189 · 2021 · Adults with healthy eyes in 46 studies (mean age 43)

    Under 5 mg to 20 mg or more per day · 3–12 months

    Macular pigment rose 0.04 units at 5 to under 20 mg/day and 0.11 units at 20 mg/day or more; intakes under 5 mg/day, mostly from food, gave no significant change.

  2. Grade CLate AMD and lung cancer over 10 years: lutein/zeaxanthin vs beta-carotene · Improved

    RCT · n 3,882 · 2022 · AREDS2 participants (mean age 72) with intermediate AMD, followed for 5 years after the trial

    10 mg lutein + 2 mg zeaxanthin per day · 10 years (5-year trial plus 5-year follow-up)

    Compared directly with beta-carotene, lutein/zeaxanthin was associated with lower progression to late AMD (HR 0.85, 95% CI 0.73 to 0.98). Lung cancer odds rose with beta-carotene (OR 1.82) but not significantly with lutein/zeaxanthin (OR 1.15).

  3. Grade CGeographic atrophy growth toward the centre of the macula · Improved

    RCT · n 891 · 2025 · AREDS2 participants with geographic atrophy (1,210 eyes)

    10 mg lutein + 2 mg zeaxanthin per day · AREDS2 trial period (annual photographs)

    In eyes with non-central atrophy (325 eyes), atrophy moved toward the fovea more slowly with lutein/zeaxanthin than without (80.1 vs 114.4 µm per year). Growth of the total atrophy area did not differ.

  4. No effectProgression to advanced age-related macular degeneration · No difference

    RCT · n 4,203 · 2013 · Adults aged 50–85 at risk of advanced AMD

    10 mg lutein + 2 mg zeaxanthin per day · Median 5 years

    Adding lutein and zeaxanthin did not further reduce progression to advanced AMD in the primary analysis.
