Lutein

vitamins

Lutein is a carotenoid antioxidant found naturally in leafy greens that accumulates in the macula of the eye, providing protection against age-related macular degeneration and oxidative stress. It works synergistically with zeaxanthin to filter harmful blue light and reduce glare sensitivity. Clinical evidence supports its role in maintaining eye health and visual function, particularly in older adults.

Benefits

Supports macular health and reduces risk of age-related macular degeneration (AMD)
Filters blue light and reduces glare, improving visual comfort
Enhances contrast sensitivity and visual performance
Provides antioxidant protection against ocular oxidative stress
May support cognitive function through brain accumulation

Research Summary

The Age-Related Eye Disease Study (AREDS2) demonstrated that lutein supplementation, particularly when combined with zeaxanthin, meso-zeaxanthin, and other nutrients, significantly reduced the progression of advanced AMD. Observational studies and randomised controlled trials consistently show that higher macular pigment optical density (MPOD), increased by lutein intake, correlates with better visual outcomes and reduced AMD risk. Current evidence supports lutein's efficacy for eye health, though optimal dosing and long-term safety require further investigation.
