I’ve read that too much Vitamin A can be toxic to animals. I want to give my dog Ocu-Clear but I’m concerned about the Vitamin A. The minimum daily requirement for Vitamin A for dogs is 50 IU/lb. or 1,250 IU daily for a 25 lb dog. The toxic level of Vitamin A is 2,500 IU /lb or 62,500 IU for a 25 lb. dog. One capsule of Ocu-Clear contains 7,500 IUs so you would be well within the safe dosage level.
Additionally, the level of Vitamin A in Ocuclear is safe for cats also. The minimum daily dose of Vitamin A for cats is 2272 IU/lb of food consumed on a dry matter basis. The toxicity level is 340,900 IU/lb of food consumed on a dry matter basis. What this means is that if your cat eats 1 cup of dry food (8 oz or 1/2 pound) then the toxicity level of vitamin A is 170,450 IU.
