Vitamin A and its precursor beta carotene are both super antioxidants that destroy carcinogens and boost immune function. Vitamin B complex (including folic acid) and B2 (riboflavin) support eye health in general, but Vitamins C and E, along with Vitamin A, are the real dog vitamin heavy hitters when it comes to vision problems. A powerful antioxidant, Vitamin C protects the other antioxidants and stimulates the immune system through the production of antiviral substances and white blood cells. As an antioxidant, Vitamin C fights the effects of free radicals and lowers your dog's risk of developing cataracts. Vitamin E is also a powerful, free radical fighting antioxidant that works in concert with Vitamin C to support your dog's vision health.
