What is it? / Overview
Turkey Tail is rich in beta-glucans and protein-bound polysaccharides (PSK and PSP) that may enhance immune cell activity. The strongest evidence comes from its use as an adjunct to conventional cancer therapy in parts of Asia, while evidence for routine use in healthy adults remains limited.
How is it used? / Administration
Form: Fruiting body extract standardized for beta-glucans (PSK or PSP-containing extracts when available)
Typical dose studied: 1–3 g/day
Timing: With meals
Most positive clinical evidence comes from oncology settings as an adjunct to standard treatment, not standalone use. For general immune support in healthy adults evidence is promising but still limited.
