Evidence Level

Strong

The AREDS2 trial (2013, JAMA) is the definitive study on nutritional supplementation for AMD. Sponsored by the NIH National Eye Institute, it enrolled 4,203 participants aged 50-85 with intermediate AMD or advanced AMD in one eye. The study confirmed that lutein/zeaxanthin was a safe and effective substitute for beta-carotene, eliminating the lung cancer risk in smokers. A 10-year follow-up (Chew et al., 2022) confirmed that the lutein/zeaxanthin formulation outperformed beta-carotene for AMD prevention.
