PSK
Polysaccharide-K, also called Krestin, is a protein-bound polysaccharide preparation derived from Trametes versicolor and studied extensively as an adjunct in some oncology settings.
Organic Polka Blend Ingredient
Turkey Tail Mushroom
Trametes versicolor
Turkey Tail is one of the four functional mushrooms in the PolkaDot Organic Polka Blend. Known scientifically as Trametes versicolor, this thin, banded wood-growing mushroom is widely studied for polysaccharides including PSK, PSP and fungal beta-glucans.

Turkey Tail Explained
01
What is Turkey Tail mushroom?
Turkey Tail is the common name for Trametes versicolor, a bracket fungus that grows on wood and is recognized by its thin, fan-shaped fruiting bodies with colorful concentric bands. The pattern can resemble the tail feathers of a turkey, which explains the common name.
Turkey Tail has a long history of traditional use and is one of the most researched medicinal mushrooms. Scientific interest focuses heavily on protein-bound polysaccharide preparations such as PSK and PSP, as well as beta-glucans and other polysaccharides.
In the Polkadot Chocolate formulation, Turkey Tail appears alongside Lion’s Mane, Reishi and Cordyceps as part of the four-species Organic Polka Blend. This creates a direct path from the ingredient guide back to the main Polkadot mushroom chocolate collection and its wider product catalog.
Inside Turkey Tail
Compounds researchers are studying.
Turkey Tail contains several groups of polysaccharides and related compounds that have been studied in laboratory, clinical and microbiome research. The evidence for one standardized extract should not automatically be generalized to every Turkey Tail supplement or food product.
PSP
Polysaccharopeptide is another protein-bound polysaccharide preparation. Human research has examined its effects on immune markers and the gut microbiome.
Beta-Glucans
Fungal beta-glucans are structural polysaccharides studied for interactions with the immune system and gut microbiota.
Research Perspective
What does the research say about Turkey Tail benefits?
Turkey Tail has more human research than many functional mushrooms, but the details matter. Much of the clinical literature involves specific standardized preparations such as PSK or PSP rather than ordinary Turkey Tail powder.
Gut Microbiome Research
A small randomized clinical trial in healthy volunteers found that a Trametes versicolor PSP preparation produced measurable changes in gut microbiome composition consistent with prebiotic activity.
Immune-Related Research
Turkey Tail polysaccharides and fungal beta-glucans have been studied for immune-modulating effects, but systematic reviews emphasize differences between products, doses and outcomes.
Oncology Adjunct Research
PSK has been studied as an adjunct to conventional treatment in some cancers and is used medically in Japan in specific contexts. That evidence relates to standardized extracts and does not make ordinary Turkey Tail products cancer treatments.
Evidence Still Has Limitations
Recent systematic reviews note small studies, heterogeneous preparations and methodological limitations. They do not support replacing standard medical care with mushroom supplements.
Turkey Tail should not be described as preventing, treating or curing cancer. Research on standardized PSK/PSP preparations is scientifically relevant, but it is not equivalent to evidence that every Turkey Tail food or supplement has the same clinical effect.
Turkey Tail in PolkaDot
One ingredient inside a four-mushroom formula.
Current PolkaDot brand information describes its Turkey Tail as certified-organic fruiting bodies grown on hardwood substrate in the USA. The brand states that the extract undergoes hot-water extraction to emphasize polysaccharide yield and is used alongside three other mushroom species in the Organic Polka Blend.

Turkey Tail FAQs
Common questions about Turkey Tail mushroom.
What is Turkey Tail mushroom?
Turkey Tail is a wood-growing mushroom known scientifically as Trametes versicolor. It forms thin, fan-shaped fruiting bodies with multicolored concentric bands.
Is Turkey Tail used in Polkadot Chocolate?
Yes. Turkey Tail is one of four mushroom species in the PolkaDot Organic Polka Blend alongside Lion’s Mane, Reishi and Cordyceps.
What are PSK and PSP?
PSK and PSP are protein-bound polysaccharide preparations derived from Trametes versicolor. They have been studied for immune-related and other biological effects, particularly in clinical research using standardized extracts.
Does Turkey Tail support the gut microbiome?
A small randomized human trial found that a Turkey Tail PSP preparation altered gut microbiome composition. This is interesting evidence, but it does not establish that every Turkey Tail product will produce the same effect.
Is Turkey Tail a cancer treatment?
No. Some standardized Turkey Tail-derived preparations have been studied as adjuncts to conventional cancer therapy in specific settings. Mushroom foods and supplements should not replace oncology care or prescribed treatment.
