A comprehensive literature search was conducted in three databases (PubMed, Cochrane Library, and Web of Science) and 20 records were identified for screening.
Based on a meta-analysis of 46 (mostly lutein/zeaxanthin) studies confirming a dose-response increase in macular pigment optical density at 5-20mg/day — a surrogate marker. Meso-zeaxanthin-specific dose-response data are thinner, hence moderate (not high) confidence.
AI-estimated from published studies. Interpret as directional guidance.
Meso-Zeaxanthin has a higher evidence score (4.5/10 vs 7/10) and wins in 2 of 3 categories.
For protect vision, AREDS2 Formula has a higher relevance score (88 vs 70).
