Keep Your Eyes Sharp with Lutein and Zeaxanthin
Your eyes are constantly working to perceive the world around you. As we age, visual sharpness and eye health tend to decline. Protecting our vision is crucial for maintaining independence and quality of life. Recent research shows that supplementing with two carotenoid antioxidants—lutein and zeaxanthin—can significantly support eye health. Read on to learn the science behind how these nutritional compounds can keep your eyes sharp.
What are Lutein and Zeaxanthin?
Lutein and zeaxanthin are carotenoids, the same family of antioxidant phytochemicals that give fruits and vegetables their vibrant colors. Unlike some other antioxidants, lutein and zeaxanthin accumulate in the retina of the eye. This is because the retina is loaded with fats, and lutein/zeaxanthin are fat-soluble nutrients.1
Within the retina is an area called the macula, which enables central, high-resolution vision. The macula is yellow in color due to its high lutein and zeaxanthin content. These two carotenoids are referred to as the macular pigments. Their job is to absorb damaging blue light that enters the eye and neutralize free radicals that accelerate macular degeneration.
How Lutein and Zeaxanthin Support Eye Health
A wealth of scientific evidence demonstrates that higher macular levels of lutein/zeaxanthin are linked with improved eye health:
- Reduces risk of age-related macular degeneration (AMD): AMD causes loss of central vision and is the leading cause of blindness in older adults. Multiple studies find that supplementing lutein/zeaxanthin slashes AMD risk by 25-40%.
- Protects retinal cells from sunlight damage: Lutein/zeaxanthin filter high-energy blue light in sunlight. This protects delicate retinal cells from oxidative damage leading to macular degeneration over time.
- Improves visual acuity: Higher macular lutein/zeaxanthin levels are linked with better visual acuity. Supplementation also improves contrast sensitivity and visibility, especially in low light conditions like night driving.
- Lowers risk of cataracts: Studies associate sufficient dietary lutein/zeaxanthin intake with up to 41% lower likelihood of developing age-related cataracts that can cause vision impairment.
Recommendations for Lutein/Zeaxanthin Supplementation
The American Optometry Association recommends supplementing 10-20 mg lutein and 2-4 mg zeaxanthin per day to support eye health. Look for a supplement derived from marigold flower extract that matches this optimal ratio.2
