Maintaining good vision is crucial, and while a balanced diet is fundamental, certain supplements can offer additional support for eye health, particularly in New Zealand where UV exposure is high. This article details key supplements, considerations, and where to find them.
Key Supplements & Their Benefits
- Lutein & Zeaxanthin: These carotenoids are concentrated in the macula, protecting against age-related macular degeneration (AMD) and cataracts. NZ studies show benefits with consistent intake.
- Omega-3 Fatty Acids: Especially DHA & EPA, vital for retinal health and reducing dry eye symptoms. Good sources include fish oil, flaxseed oil (ALA conversion is less efficient).
- Vitamin C: A powerful antioxidant, protecting against oxidative stress, a major contributor to cataracts and AMD. Kiwi fruit, a NZ staple, is a great dietary source.
- Vitamin E: Another antioxidant, working synergistically with Vitamin C. Protects cell membranes in the eyes.
- Zinc: Helps Vitamin A create melanin, a pigment protecting the retina. Important for night vision.
- Astaxanthin: A potent antioxidant, potentially protecting against glaucoma and macular degeneration.
Specific Eye Conditions & Supplement Support
- Age-Related Macular Degeneration (AMD): Lutein, Zeaxanthin, Vitamin C, Vitamin E, Zinc, Omega-3s.
