Vitamin A is essential to good vision health and may reduce the incidence of cataracts, so be sure to look for a dog vitamin product that contains plenty of this vitamin. 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. Vitamin C is a powerful antioxidant that protects other antioxidants, like Vitamin E, and supports your dog's immune system by stimulating 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.
