Ask the NorthStar VETS Vet: I’m-Yunity extract for dogs with cancer

Q: My 11 year old Lab was recently diagnosed with a splenic mass via ultrasound at your facility. Unfortunately, the mass ruptured prior to being able to get her into surgery. She did have emergency surgery at another specialty hospital and the spleen and mass were removed. She is doing FANTASTIC! The biopsy came back as a probable Hemangiosarcoma, but her liver biopsy was clean. We are opting NOT to give her Chemo. My vet mentioned to me a drug that the University of Penn did studies with, a mushroom extract called I’m Yunity. Do you know anything about this and would you suggest giving her these supplements?

A: More information can be found on that study at

From this link you can see that this supplement does increase survival from 86 days to 199 days in dogs that have only had surgery at the 100mg/kg group. What hasn’t been published yet is the survival data for other dosage groups. They did say that the other treatment groups were statistically the same. Please keep in mind that a 1 week supply for an 80 pound dog is ~$100 so this doesn’t come cheap, but they also mention no side effects, which is great. I have personally never used this supplement, but would be interested in using it if a client was interested.
