When to Supplement Protect the eyes

Antioxidant carotenoid pigments lutein and zeaxanthin act as nature’s sunglasses, protecting eyes from sun damage and supporting the macula, part of the retina that degenerates with age, causing gradual loss of sight. High levels of lutein and zeaxanthin seem also to boost immunity and protect against heart disease, breast and lung cancer, and age-related brain deterioration. Natural food sources are red peppers, pumpkin, carrots, sweet potatoes, and corn; dark green vegetables such as spinach, broccoli and kale. Absorption from enriched eggs may be 200–300 percent more efficient than from other food and supplements. Alternatively, take 6 mg lutein and 0.1-0.2 mg zeaxanthin daily.
