What is Turkey Tail?
Turkey Tail (Trametes versicolor) is one of the most common and well-studied medicinal mushrooms in the world. Named for its colorful, fan-shaped fruiting bodies that resemble turkey tail feathers, it grows on dead logs throughout forests worldwide.
PSK and PSP
Turkey Tail contains two heavily researched polysaccharide compounds: PSK (Polysaccharide-K, also called Krestin) and PSP (Polysaccharopeptide). PSK has been approved as an adjunctive treatment in Japan since the 1970s for its immune-supporting properties.
Immune System Research
Turkey Tail is the most clinically studied mushroom for immune support. Research shows it activates multiple types of immune cells, including natural killer cells, T-cells, and dendritic cells.
Gut Health
Turkey Tail acts as a prebiotic, feeding beneficial gut bacteria. Studies show it can increase populations of Bifidobacterium and Lactobacillus while reducing potentially harmful bacteria, supporting overall microbiome health.
Quality Considerations
Look for products made from the fruiting body (not mycelium on grain) with verified beta-glucan content. Hot water extraction is sufficient for Turkey Tail's water-soluble polysaccharides.
