I’m‑Yunity contains standardized polysaccharopeptide (PSP) from Coriolus versicolor. PSP has immune-modulating activity, and some studies of other beta-glucan products have reported improvement in itching or skin scores in dogs with atopic dermatitis.
I’m‑Yunity may have potential as supportive nutritional therapy for allergic dogs because of PSP’s immunomodulatory properties, but its effectiveness for canine allergies has not yet been clinically established.
