Vitamin E for Dog Cancer: Can I Give It During Chemo? | Dr. Nancy Reese Q&A

Is it okay to give your dog vitamin E during chemotherapy, or will it make the chemo not work? Dr. Nancy Reese explains.


Caller Bevan has a dog with mast cell tumors, and his vet recommended giving vitamin E as part of their treatment plan. Vitamin E is an antioxidant, which protects cells from damage. Chemotherapy is a pro-oxidant, with the intent to damage cells – specifically, cancer cells. Dr. Nancy Reese explains how these conflicting mechanisms of action can be problematic in some cases, but coexist peacefully in other, as well as why your vet might recommend giving vitamin E in the first place.
