Supplementing Vitamin C in your dog’s diet can have important anti-oxidant benefits, especially during times of stress such as travel, boarding, and illness or pre and post surgery. This specially formulated Ester-C is natural, non-acidic, and contains metabolites that have been shown to enhance the delivery of Vitamin C to the body’s cells. It will not cause stomach upset or erode tooth enamel, the way some Vitamin C supplements can. Each chewable tablet is 250mg of Ester-C.
