As dogs age, they may develop vision issues due to oxidative damage and blue light exposure. Lutein, a carotenoid antioxidant, accumulates in the retina and helps protect eye cells. Our team of veterinary experts reviewed five leading lutein supplements, evaluating ingredients, formulation, and owner feedback. We looked for products with clinically relevant lutein doses, complementary nutrients like DHA and vitamin E, and palatable forms that dogs actually eat. Each pick reflects our commitment to practical, evidence-based recommendations for your pet’s eye health.
