Evidence notes

Good evidence exists for zeaxanthin's role in eye health, particularly from the AREDS2 trial and observational studies showing association between dietary zeaxanthin intake and reduced AMD risk. Evidence is solid but less extensive than for lutein. Most benefits are observed when combined with lutein and other nutrients.

Grade B: Some human trials support key claims; further confirmation needed.
