UltraCruz® Canine Antioxidant Supplement for Dogs

UltraCruz® Canine Antioxidant Supplement for Dogs is a Selenium, Vitamin C and Vitamin E formula that supports healthy tissues, organs and cellular health. Hard working dogs such as those involved in herding, agility, or any active lifestyle may especially benefit from these tasty chews.

What is an antioxidant?

Antioxidants such as Vitamin C, Vitamin E and Selenium are substances that neutralize free radicals to support healthy tissues and organs on a cellular level. Antioxidant support is recommended for horses subject to rigorous exercise and may help to reduce the negative effects of oxidative stress.

What is a free radical?

Free radicals are highly reactive chemicals with the potential to cause damage to cells. Free radicals can be produced naturally by the body during times of heavy exercise.

My schnauzer weighs around 12 lbs, would I cut this vitamin in half or do you offer a chewable vitamin for smaller than 30 lb dogs? 

Asked by: Phoenix
Hello, The recommended dosage for this product is 1 chew twice a day for every 30 lbs. You may administer half a chew twice a day for your dogs weight.

Rated 5 out of 5 by from Right amount of vitamins and seleniumI bought this supplement for my German Shepherd puppy who had down pasterns. Her pasterns are almost normal after 3 weeks of supplementing with Ultra Cruz Canine Antioxidant formula, in combination with Glucosamine, Chondroitin and Prozyme. I recommend it without hesitation

Rated 5 out of 5 by from Good product.I purchased many of these. I have some dogs that do not like the flavor. They spit it out. Others really eat it up fast. It depends on the dog. I like the product in itself. If anything is to change maybe re-visit the flavor! :) - As always, good products!
