Turkey tail Extract | Highly Active Polysaccharides for Immune System Support

2026-04-05

Turkey tail Extract is a natural active ingredient refined using modern extraction techniques from the fruiting bodies or mycelium of Poria cocos, a fungus belonging to the Polyporaceae family. Its core components are Poria polysaccharides (PSK and PSP), which offer multiple benefits including immune modulation, liver protection and antioxidant properties, and are widely used in the pharmaceutical, health supplement and food industries.

I. Basic Product Information

Product Name: Turkey tail Extract Source: Dried fruiting bodies / high-quality mycelium of the polypore fungus Phellinus linteus.

Core Active Ingredients: Turkey tail polysaccharides (PSK, PSP), triterpenoids, steroids, amino acids, trace elements, etc.

Product Specifications: Polysaccharide content 10%/20%/30%/50%; Extraction ratio 10:1/20:1/50:1 (customisable).

Appearance: Fine powder ranging from light brown to dark brown, loose and free of lumps, easily soluble in hot water, odourless.

II. Core Efficacy and Mechanism of Action

1. Potent Immune Modulation (Core Value)

As a biological response modifier, Turkey tail polysaccharides (PSK, PSP) activate macrophages, T lymphocytes and NK cells, promote the secretion of cytokines such as IL-2 and IFN-γ, and bidirectionally regulate immune function. They enhance the body’s ability to recognise and eliminate pathogens and abnormal cells, thereby improving immunodeficiency.

2. Adjuvant Cancer Therapy

By enhancing the body’s immune surveillance function, inhibiting tumour cell proliferation and inducing apoptosis, it can, when used in combination with radiotherapy and chemotherapy, alleviate bone marrow suppression and gastrointestinal reactions, improve treatment tolerance and reduce the risk of recurrence. It is an internationally recognised adjuvant ingredient for cancer immunotherapy.

3. Liver Protection

It repairs damaged liver cells, inhibits the activation of hepatic stellate cells, reduces levels of transaminases such as ALT and AST, alleviates liver damage caused by alcohol, drugs and viruses, and helps improve symptoms of chronic hepatitis, fatty liver and liver fibrosis.

4. Antioxidant and Anti-fatigue Effects

Scavenges free radicals such as DPPH and ABTS, enhances SOD activity, and reduces oxidative stress damage; regulates energy metabolism, reduces lactic acid accumulation, alleviates chronic fatigue, and delays cellular ageing.

5. Other Health Benefits

Regulation of blood lipids: Inhibits cholesterol absorption, promotes bile acid excretion, and assists in lowering total cholesterol and LDL

Assistance with blood sugar control: Enhances insulin sensitivity, improves glucose tolerance, and stabilises blood glucose levels

Anti-inflammatory and antiviral: Inhibits the release of inflammatory factors and has an auxiliary inhibitory effect on viruses such as influenza, hepatitis B and HPV
