No, they are not. Turkey Tail Mushroom, also known as Coriolus Versicolor, is a common type of mushroom that has the shape and color of a turkey tail. What is unique about the Turkey Tail Mushrooms that we use in Critical Immune Defense is the mushrooms are harvested at a very young age when the polysaccharide K (PSK) and peptides are the most concentrated, and these active compounds boost the immune system. As a reference, polysaccharide K (PSK) is an approved mushroom product to treat cancer in Japan.
