Lutein + Zeaxanthin
Lutein and Zeaxanthin
Carotenoid pigments that accumulate in the eye, providing protection against blue light and age-related vision decline.
Lutein and zeaxanthin are carotenoids found in high concentrations in the macula of the eye, where they form macular pigment that filters harmful blue light and provides antioxidant protection. Strong evidence supports their role in reducing risk of age-related macular degeneration (AMD) and cataracts. Also beneficial for reducing digital eye strain.
Mechanisms of Action
Blue Light Filter
Absorbs harmful blue light before it damages retinal cells
Antioxidant Protection
Neutralizes free radicals in the eye
Recommended Dose
10mg lutein + 2mg zeaxanthin
Optimal Timing
- With a meal containing fat
Take with food
Best Form
Softgels with both lutein and zeaxanthin
Alternatives: FloraGLO lutein (most studied), Lutein esters
Free-form lutein may absorb better than lutein esters. Look for products with both lutein and zeaxanthin in ~5:1 ratio.
Duration
Minimum: 12 weeks
Optimal: 24 weeks
Cycling: Not required
Note: Fat-soluble carotenoids — absorption improves significantly with dietary fat. Can be taken any time of day.
Macular Protection
Increases macular pigment optical density
Reduced Eye Strain
Less fatigue from screens and bright light
Better Glare Recovery
Faster recovery from bright light exposure
Safe at recommended doses; found naturally in breast milk
Safe (unlike beta-carotene, no lung cancer concern)
Drug Interactions
May compete for absorption — take separately
Possible Side Effects
Tip: Harmless and reversible; reduce dose
Warnings
- Takes months to build up macular pigment — be patient
- Not a replacement for regular eye exams
