Turkey tail mushrooms (Trametes versicolor), also known as Yun Zhi in China and kawaratake in Japan, are multicolored fungi that grow on tree trunks and fallen logs in various parts of the world, including the United States. Resembling a turkey’s tail, these mushrooms have been used in traditional herbal medicine for centuries. Today, they are gaining popularity as a complementary treatment for various health conditions, including cancer and weight management. This article explores the potential health benefits of turkey tail mushrooms, focusing on their role in weight loss and overall well-being.
Understanding Turkey Tail Mushrooms
Turkey tail mushrooms are polypore fungi, meaning they have pores on the underside of the cap instead of gills. They are saprophytic mushrooms, obtaining their nourishment from decomposing, dead organic matter. This process helps recycle nutrients back into the environment, playing an important role in forest ecosystems. While not a culinary delight, turkey tail mushrooms contain properties that support the body’s immune response and offer other functional benefits.
Nutritional Profile of Turkey Tail Mushrooms
Turkey tail mushrooms are a source of dietary fiber and boast two significant active components: Polysaccharopeptides (PSPs) and Polysaccharide-K (PSK). These compounds are believed to bolster immune function and may positively impact the gut microbiome. Additionally, turkey tail mushrooms contain antioxidants, including flavonoids and phenols, which can support the body’s natural defenses against oxidative stress.
Potential Weight Loss Benefits of Turkey Tail Mushrooms
The connection between turkey tail mushroom and weight loss has been a topic of interest, with research exploring how incorporating turkey tail can promote a healthy weight. While not a magic bullet, turkey tail mushrooms may have a beneficial effect on weight loss through several mechanisms:
- Regulation of Metabolism: One of the key compounds found in turkey tail mushroom is beta-glucans, a type of dietary fiber that has been shown to have a beneficial effect on weight loss. Beta-glucans are thought to help regulate the body's metabolism by slowing down the absorption of carbohydrates, which can lead to a reduction in blood sugar levels and a decrease in fat storage.
- Promotion of Gut Health: Turkey tail mushrooms are rich in PSPs and PSK, which feed the beneficial bacteria that help maintain a healthy digestive system. A healthy gut contributes to better body metabolism, which can subsequently affect body weight.
- Anti-inflammatory Properties: Turkey tail mushrooms are well-known for their potent anti-inflammatory properties. By reducing inflammation, these mushrooms may indirectly support weight management.
- Low-Calorie and High-Fiber Content: Turkey tail mushrooms are low in calories and high in fiber, a combination that can support weight management. The presence of polysaccharides can aid in maintaining your weight with evidence-based properties that have been observed to support a healthy appetite.
- Glucose Regulation Properties: The fiber contained in mushrooms is water-soluble, which is the type of fiber that slows down digestion and helps reduce glucose spikes. Due to this reason, it’s believed that regular consumption of mushrooms can help delay the body’s absorption of glucose and thus, help you lower blood glucose levels.
Immune-Boosting Properties
A number of studies have shown that turkey tail mushrooms have immune-boosting properties, which may benefit people undergoing cancer treatment. Turkey tail mushrooms contain compounds known as polysaccharopeptide (PSP) and polysaccharide-K (PSK). Some evidence suggests that PSP may have the ability to stimulate the immune system, especially when combined with other anticancer treatments. In Japan, PSK is an approved adjuvant cancer treatment. However, the Food and Drug Administration (FDA) has not approved the product as a medication in the United States.

Potential Benefits for Specific Types of Cancer
- Colon Cancer: PSP from turkey tail extract may inhibit colon cancer cell growth and stop colon cancer cells from migrating and invading healthy cells. PSK from turkey tail mushrooms may help reduce the side effects of an oral chemotherapy regimen for colorectal cancer.
- Gastric Cancer: PSK may prolong overall survival times, with the most effect in people with programmed death-1 ligand 1 negative (PD-L1) negative tumors, which usually do not respond well to immunotherapy.
- Breast Cancer: Turkey tail extract contributed to increased levels of cancer-fighting cells in the immune system in a small phase 1 clinical trial. However, more clinical trials involving larger numbers of participants are necessary to draw any conclusions.
Gut Health Benefits
The compounds in turkey tail may also benefit gut health. As with most mushrooms, turkey tail contains fiber, which helps maintain healthy digestion. Turkey tail mushrooms may also promote healthy gut bacteria. This mushroom can alter a person’s microbiome and may cause the body to regulate its own microbiome. Having a healthy balance of bacteria in the gut is essential for health and may help prevent other conditions. Turkey tail mushroom has antibacterial properties against several common pathogens, such as Staphylococcus aureus, Escherichia coli, and Listeria. However, studies differ on how strong these effects may be, and not many have tested turkey tail extracts as solo treatments for these infections in humans.
Other Potential Health Benefits
Beyond weight loss, immune support, and gut health, turkey tail mushrooms may offer additional health benefits:
- Antioxidant Properties: Turkey tail mushrooms are packed with a variety of antioxidants, including flavonoids and phenols, which can support the body’s natural defenses against oxidative stress.
- Liver Protection: Turkey tail mushroom extracts may be beneficial for overall liver function, especially in livers damaged by disease.
- Nervous System Function: Turkey tail mushrooms and their extracts may also be beneficial for brain function by protecting against cell damage caused by oxidative stress.
- Antiviral Activity: Turkey tail mushroom extracts may be useful in treating viral infections, such as HIV and HPV.
- Improved Athletic Performance: Turkey tail mushroom supplements may help with athletic performance by improving physical exercise endurance.
- May combat HPV: A study found that a turkey tail-based vaginal gel had a positive effect on women with a Human Papillomavirus (HPV) infection.
- May improve insulin resistance: A study in rats with type 2 diabetes demonstrated that turkey tail extract significantly reduced blood sugar levels and improved insulin resistance
Incorporating Turkey Tail Mushroom into Your Diet
Turkey tail mushrooms come in various forms, including capsules, powders, and tinctures. Turkey tail extract is potent and easy to add to various meals, while turkey tail mushroom powder can be easily mixed into smoothies or used in cooking.
- Supplements: Turkey tail mushroom supplements are a convenient way to get the benefits of turkey tail mushroom without having to cook and prepare the mushroom itself.
- Tea: Some people chop dried turkey tail mushrooms and steep them at home to make tea.
- Cooking: Dried turkey tail mushrooms can be used in cooking, adding them to soups, stews, or broths.
- Powder: Turkey tail mushroom powder can be added to soups, stews, or even beverages like tea or mushroom coffee, providing a health boost without significantly altering the flavor.
A standard recommendation for turkey tail mushroom weight loss is to consume it 2-3 times a day. However, consulting with a healthcare professional before starting any new supplement regimen is crucial to ensure it suits your health circumstances.
Safety and Precautions
Generally, studies on PSK report few side effects. Anecdotally, some people report upset stomach, nausea, bloating, and heartburn. Additionally, because turkey tail is a fungus, anyone with a mushroom or mold allergy should not use it, as it could cause a life threatening reaction known as anaphylaxis. It is also important to note that not all dietary supplement products are safe. Mushrooms can accumulate metals from the environment in which they grow, some of which can be dangerous. For this reason, it is important to look for a purified supplement or for dried mushrooms from a reputable source when buying turkey tail mushrooms or extract. Ideally, the product should undergo testing by a third party to prove its safety.

People should not consume turkey tail mushrooms in the wild. The soil or the area around the mushroom could be contaminated with pollutants or bacteria. In addition, some types of mushrooms are poisonous. It can be difficult to know which ones are safe. Follow the dosage instructions carefully and do not take more than the label recommends. Anyone with an underlying health condition should consult a doctor before trying any new supplement, including turkey tail extract. If side effects occur, speak with a doctor, particularly if undergoing other medical treatments.
Choosing the Right Turkey Tail Supplement
To avoid weak or tainted mushroom supplements, be sure to buy from a reputable, organic supplier who uses the whole mushroom and tests its product for heavy metals and other toxins. Ensure you opt for supplements that come from reputable suppliers, preferably those that engage in organic farming practices. Look for products that list the beta-glucan content.
Potential Side Effects
Turkey tail mushroom is considered safe, with few side effects reported in research studies. Some people may experience digestive symptoms like gas, bloating, and dark stools when taking turkey tail mushroom. When used as a cancer treatment alongside chemotherapy, side effects including nausea, vomiting, and loss of appetite have been reported. Another potential side effect of consuming turkey tail mushroom is the darkening of the fingernails. Even though it has a good safety profile, it’s important to speak with your doctor before supplementing with turkey tail mushroom.
Drug Interactions
While Turkey Tail Mushroom is a natural supplement, it can still interact with certain substances. For instance, because of its immune-boosting properties, it might interfere with immunosuppressive medications. Other weight loss supplements could have their own interactions and side effects, and combining them could amplify these effects or lead to unexpected reactions. Pregnant and nursing women should always consult their healthcare provider before taking any new supplement, including Turkey Tail Mushroom.
