About Lutein
Lutein is a xanthophyll carotenoid that accumulates in the macula and lens of the eye, where it filters harmful blue light and acts as an antioxidant. The AREDS2 trial (5,000+ participants) confirmed lutein + zeaxanthin reduced the risk of advanced AMD progression. Unlike beta-carotene, lutein is safe for smokers. Also found in skin where it protects against UV-induced damage. Not synthesized by the body — must come from diet (leafy greens, egg yolks) or supplementation. No established RDA/UL.
What Lutein supports
- Accumulates in the macula — filters blue light and protects against AMD
- AREDS2 trial confirmed benefit for macular degeneration risk reduction
- Also protects skin against UV-induced oxidative damage
- Potent antioxidant — safe alternative to beta-carotene for all populations
How much Lutein to take
Clinical studies typically use 10–20 mg of Lutein. AREDS2 study used 10 mg/day; common eye health supplement dose.
- Effective range
- 10–20 mg
Clinical evidence
Strong clinical evidence. AREDS2 trial with 5,000+ participants confirmed benefit for macular degeneration risk reduction
