About Turkey Tail Mushroom
Turkey tail contains PSK (polysaccharide-K) and PSP (polysaccharopeptide), two protein-bound polysaccharides with strong immunomodulatory evidence. PSK is an approved adjunctive cancer therapy in Japan with multiple RCTs showing improved survival in gastric and colorectal cancer patients. A 2012 NIH-funded Phase I trial showed dose-dependent immune activation in breast cancer patients. Among the most clinically studied medicinal mushrooms. Generally well tolerated.
