Turkey Tail Whole Fruiting Body Mushroom Powder

Turkey Tail contains some of the highest beta-glucan concentrations of any mushroom — alongside two signature polysaccharides, PSK and PSP. These naturally occurring compounds are among the most widely studied in the world of functional mushrooms, and their abundance in the fruiting body is one of Turkey Tail's defining qualities.

PSP — one of Turkey Tail's two key polysaccharides — is a prebiotic fiber, a category of naturally occurring compounds found in many whole foods. Prebiotic compounds are a well-recognized component of whole-food nutrition and part of the reason Turkey Tail has been valued in culinary and tea traditions for so many generations.

Turkey Tail contains over 35 different phenolic compounds alongside naturally occurring flavonoids including quercetin and baicalein. The breadth and diversity of Turkey Tail's phenolic profile is exceptional even among functional mushrooms — and contributes to its distinctive character.

Turkey Tail has been used in traditional wellness practices across China and Japan for centuries. Its long history as a staple of Traditional Chinese Medicine and Japanese Kawaratake tradition speaks to the deep cultural value placed on this mushroom — a tradition Hongo carries forward with our whole fruiting body sourcing.

🔬 PSK — Polysaccharide K

PSK, also called Krestin, is one of Turkey Tail's two signature polysaccharide compounds. It is one of the most extensively documented natural compounds in mycology research, with decades of laboratory study in Japan and China. PSK is found in high concentrations specifically in the fruiting body — which is why whole fruiting body sourcing matters.

🧬 PSP — Polysaccharide Peptide

PSP is Turkey Tail's second key polysaccharide — distinct from PSK and with its own unique structure. It is classified as a prebiotic fiber. Together, PSK and PSP form the distinctive compound profile that makes Turkey Tail one of the most recognizable mushrooms in the functional mushroom category.
