Trametes versicolor Extract (Fruiting Body)

Also known as: Turkey Tail Mushroom, Coriolus versicolor, Polyporus versicolor, Turkey Tail Extract

C
Evidence

Trametes versicolor is a medicinal mushroom rich in beta-glucans and bioactive polysaccharides, traditionally used in Asian medicine to support immune function and gut health. Clinical research, primarily from Asia, suggests potential benefits for immune support and as an adjunctive therapy, though evidence in Western populations remains limited.

Primary uses

  • Immune system support
  • Gut health and microbiome
  • General wellness
  • Antioxidant support

How it works

  • Beta-glucan polysaccharides activate immune cells (macrophages, NK cells, T cells)
  • Prebiotic effects supporting beneficial gut bacteria
  • Antioxidant and anti-inflammatory activity from phenolic compounds

Dosage

Typical range
1,000-3,000 mg daily (fruiting body extract); 1,000-2,000 mg daily (standardized PSK/PSP)
Timing
Can be taken any time of day; with meals may improve absorption
With food
Recommended with food to improve tolerability and polysaccharide absorption
Duration
Benefits typically appear after 4+ weeks of consistent use; research protocols often use 3-12 months
Special populations
Generally safe for most adults; limited safety data in children or during pregnancy/lactation

Forms

  • Capsules· 70/100
  • Powders· 70/100
  • Liquid extract· 70/100
  • Dried fruiting body· 70/100

Safety

Common side effects

  • Mild gastrointestinal upset or bloating
  • Loose stools (from prebiotic effects)
  • Rare allergic reactions in sensitive individuals

Contraindications

  • Avoid if allergic to mushrooms or molds
  • Use with caution in autoimmune conditions (may overstimulate immune response)
  • Potential interaction with immunosuppressant medications

Evidence notes

Moderate evidence from Asian clinical trials (particularly PSK/PSP extracts) showing immune and gut health benefits, but limited high-quality RCT data in Western populations. Many studies are small or from single research centers. Stronger evidence exists for specific standardized extracts (PSK, PSP) than for general fruiting body extracts.

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
