Turkey tail mushrooms (Trametes versicolor) have been studied for their potential benefits in prostate cancer, primarily due to their bioactive compounds, polysaccharopeptide (PSP) and polysaccharide-K (PSK). Below is a summary of their properties and potential effects based on available research:
Key Properties and Mechanisms
1. **Immunomodulatory Effects**:
– **PSP and PSK**: These compounds are known to enhance immune function by stimulating immune cells such as natural killer (NK) cells, dendritic cells, and T-cells. They may improve the body’s ability to recognize and fight cancer cells.[](https://well-gummies.com/blogs/infos/turkey-tail-mushrooms-for-prostate-cancer)[](https://www.healthline.com/nutrition/turkey-tail-mushroom)
– Studies suggest that turkey tail mushrooms act as nonspecific immune modulators, bolstering immune response, which is critical for cancer patients, especially during treatments like chemotherapy.[](https://www.uclahealth.org/news/article/turkey-tail-mushrooms-act-as-nonspecific-immune-modulators)[](https://www.lungcancercenter.com/news/turkey-tail-mushroom-cancer/)
– A 2012 clinical trial showed that turkey tail extract improved immune function in breast cancer patients post-radiation, suggesting potential benefits for immune recovery in other cancers, including prostate.[](https://www.uclahealth.org/news/article/turkey-tail-mushrooms-act-as-nonspecific-immune-modulators)
2. **Anti-Cancer Stem Cell Activity**:
– PSP has been shown to target prostate cancer stem cells (CSCs), which are often resistant to conventional therapies and contribute to cancer initiation and relapse. In a 2011 study, PSP treatment of the prostate cancer cell line PC-3 reduced CSC markers (CD133 and CD44) and inhibited the formation of prostaspheres, indicating suppression of CSC properties.[](https://pmc.ncbi.nlm.nih.gov/articles/PMC3095629/)[](https://pubmed.ncbi.nlm.nih.gov/21603625/)[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3095629/)
– In vivo studies with transgenic mice (TgMAP) that spontaneously develop prostate tumors showed that oral PSP administration for 20 weeks completely prevented tumor formation, highlighting its chemopreventive potential.[](https://pmc.ncbi.nlm.nih.gov/articles/PMC3095629/)[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3095629/)
3. **Antioxidant Properties**:
– Turkey tail mushrooms contain over 35 phenolic and flavonoid antioxidants, including quercetin and baicalein, which reduce oxidative stress and inflammation. These antioxidants may help protect cells from damage that could contribute to cancer development.[](https://www.lungcancercenter.com/news/turkey-tail-mushroom-cancer/)[](https://www.healthline.com/nutrition/turkey-tail-mushroom)
– Oxidative stress is linked to increased cancer risk, and turkey tail’s antioxidants may support overall cellular health.[](https://www.healthline.com/health/cancer/turkey-tail-mushroom-cancer)
4. **Anti-Tumor Effects**:
– PSP has been shown to promote apoptosis (programmed cell death) of cancer cells and inhibit angiogenesis (the formation of new blood vessels that tumors need to grow).[](https://well-gummies.com/blogs/infos/turkey-tail-mushrooms-for-prostate-cancer)
– A 2011 study demonstrated that PSP extracted from turkey tail mushrooms suppressed prostate tumor formation in mice by targeting cancer stem cells, achieving 100% tumor prevention compared to controls.[](https://www.sciencedaily.com/releases/2011/05/110523091539.htm)[](https://www.thehindu.com/sci-tech/health/medicine-and-research/mushrooms-can-beat-prostate-tumours/article2044688.ece)
5. **Synergistic Effects with Conventional Therapies**:
– Turkey tail extracts, particularly PSK, are used in Japan as an adjunct to chemotherapy and radiation for various cancers, including prostate, to enhance treatment efficacy and reduce side effects.[](https://bastyr.edu/about/news/fda-approves-bastyr-turkey-tail-trial-cancer-patients)[](https://www.lungcancercenter.com/news/turkey-tail-mushroom-cancer/)[](https://www.canceractive.com/article/mushroom-extract-to-be-tested-in-integrative-cancer-treatment-role)
– Research indicates that PSK may improve survival rates and quality of life in patients with certain cancers, though specific data for prostate cancer is less extensive.[](https://www.medicalnewstoday.com/articles/turkey-tail-mushroom)
Clinical Evidence
– **2011 Study (PLoS ONE)**: Conducted by Dr. Patrick Ling at Queensland University of Technology, this study found that PSP from turkey tail mushrooms completely suppressed prostate tumor development in mice by targeting cancer stem cells. This was a significant finding, as other inhibitors tested previously were only up to 70% effective.[](https://www.sciencedaily.com/releases/2011/05/110523091539.htm)[](https://www.thehindu.com/sci-tech/health/medicine-and-research/mushrooms-can-beat-prostate-tumours/article2044688.ece)[](https://www.osadha.com/turkey-tails-prostate-cancer/)
– **FDA-Approved Trial (2012)**: A clinical trial at Bastyr University, funded by the NIH, investigated turkey tail extract in combination with chemotherapy for advanced prostate cancer patients. The trial aimed to assess its immune-boosting effects, though specific results on efficacy were not detailed in the provided sources.[](https://bastyr.edu/about/news/fda-approves-bastyr-turkey-tail-trial-cancer-patients)
– **General Cancer Studies**: While most clinical trials focus on breast, lung, gastric, and colorectal cancers, the mechanisms (immune modulation, anti-tumor effects) suggest potential applicability to prostate cancer. A 2019 review of 23 trials with over 4,200 patients found that PSK and PSP improved survival and quality of life in some cancer patients.[](https://www.healthline.com/health/cancer/turkey-tail-mushroom-cancer)[](https://www.lungcancercenter.com/news/turkey-tail-mushroom-cancer/)
Dosage and Administration
– **Typical Dosage**: Studies and reviews suggest a dosage of 1–3 grams of turkey tail mushroom extract (powdered or capsule form) daily, divided into 2–3 doses. However, exact dosages should be tailored by a healthcare provider based on individual needs and treatment plans.[](https://well-gummies.com/blogs/infos/turkey-tail-mushrooms-for-prostate-cancer)
– **Form**: Extracts like PSK or PSP are more effective than consuming whole mushrooms due to higher concentrations of bioactive compounds. Eating raw or cooked turkey tail mushrooms is less likely to provide the same therapeutic benefits.[](https://www.sciencedaily.com/releases/2011/05/110523091539.htm)[](https://draxe.com/nutrition/turkey-tail-mushroom/)
Safety and Precautions
– **Side Effects**: Turkey tail mushrooms are generally well-tolerated, but some individuals may experience mild side effects like nausea, bloating, or dark stools. Those receiving chemotherapy and PSK have reported nausea, vomiting, or liver issues, though it’s unclear if these are due to PSK or chemotherapy.[](https://www.webmd.com/vitamins/ai/ingredientmono-648/turkey-tail-mushroom)[](https://www.lungcancercenter.com/news/turkey-tail-mushroom-cancer/)
– **Allergies**: People with mold or mushroom allergies should avoid turkey tail mushrooms, as they may cause allergic reactions.[](https://www.lungcancercenter.com/news/turkey-tail-mushroom-cancer/)
