Vitamin B12 traditionally has been administered parenterally for chronic enteropathies and EPI. It can be challenging for clients to bring their pets in monthly for these injections. Recent studies have found that daily oral administration of cyanocobalamin will just as effectively increase serum cobalamin levels as monthly injections. Rx Vitamins proudly introduces Rx B12, in a highly palatable liquid format for easy and convenient oral administration of cyanocobalamin to your patients. The 120 ml bottle will supply a larger (>50 pounds) patient for a month, and for a patient less than 25 pounds it will last 4 months.
