Evidence Level

Strong

Lutein has robust clinical evidence, anchored by the AREDS2 trial (2013, JAMA, n=4,203), which established lutein 10 mg + zeaxanthin 2 mg as the preferred carotenoid combination for AMD. A 10-year follow-up confirmed lutein/zeaxanthin was superior to beta-carotene for reducing late AMD risk by approximately 20%. Epidemiological data consistently associates higher lutein intake with reduced risk of both AMD and cataracts.

Evidence by Condition

Condition	Studied Dose	Evidence
AMD prevention	10 mg daily with 2 mg zeaxanthin	Strong
Blue light protection	10-20 mg daily	Moderate
Cataract risk reduction	6-10 mg daily	Moderate
Macular pigment density	10-20 mg daily for 6+ months	Strong
