FAQ about I’m-Yunity®

Common queries and the answers for a better understanding of I’m-Yunity®.

Q: Are there any side effects of I’m-Yunity®?

A: There have been no reported true side effects using I’m-Yunity®. However, we recommend consulting with your veterinarian if your pet is on medications that suppress immune function or if your pet has an autoimmune disease. Since I’m-Yunity® is designed to support healthy immune function.

If your pet has a mushroom allergy then I’m-Yunity® may not be right for your pet too.

Q: Can I’m-Yunity® be used in cats or other animals?

A: Currently, I’m-Yunity® has only been evaluated for safety and efficacy in dogs. Animal species other than dogs may react differently to I’m-Yunity®, so we cannot guarantee its safety and efficacy in all animal species. If there is not a medical reason why your animal cannot have a mushroom extract, then I’m-Yunity® would be considered reasonable to try for immune supplementation. We recommend discussing the use of I’m-Yunity® in any animal other than a dog with your veterinarian prior to use.

Q: For I’m-Yunity®, are there any learned interactions with drugs or herbs?

A: We have a study “In vivo effect of I’m-Yunity on hepatic cytochrome P450 3A4”, which investigated the ability of I’m-Yunity to inhibit or induce the drug metabolism of CYP3A4 in healthy adult human subjects. (The link to the abstract on Medline is here, if you need the full report please email us.) Some chemo drugs fall into this category. The results suggests that the administration of I’m-Yunity® with other medications and dietary supplements, which are primarily metabolized on this pathway, is not expected to be associated with significant herb-drug interactions. If you use any of the chemo drugs that are metabolized on this pathway, chances are you have a better safety profile using concomitantly.

As this study was done in human, it is difficult to say if the results would be the same in dogs without repeating a drug interaction study. However, in animal toxicity studies yunzhi was considered safe in doses up to 18g/kg in acute toxicity testing¹ and 6g/kg in a sub chronic toxicity testing².
