What is Turkey Tail?
Turkey tail (Trametes versicolor) is one of the most researched medicinal mushrooms, valued for two unique beta-glucan compounds, PSK (polysaccharide-K) and PSP (polysaccharopeptide). These act as prebiotics that nourish beneficial gut bacteria and as immune modulators that prime natural killer cells and macrophages. PSK is an approved adjunct cancer therapy in Japan, though over-the-counter extracts are positioned for general immune and gut support, not treatment. Look for a hot-water or dual extract standardized to beta-glucans, not plain mushroom powder or mycelium grown on grain. Typical intake is 1-3 g of extract daily.
