Turkey Tail is a common polypore mushroom found worldwide, named for its striking concentric rings of color that resemble a turkey’s tail.
It grows on dead hardwood logs and is packed with beneficial bioactive compounds like beta-glucans, flavonoids, phenols, and polysaccharides PSK and PSP.
These substances give it potent antioxidant, anti-inflammatory, immune-modulating, and neuroprotective properties.
How Bioavailible is Turkey Tail Mushroom?
Turkey Tail’s active compounds, especially the polysaccharides, are highly bioavailable when properly extracted.
Hot water extraction is the traditional method that breaks down indigestible chitin to increase bioavailability.
Standardized Turkey Tail extracts optimized for PSK and PSP content tend to have the highest bioavailability and potency.
According to research, up to 70% of orally administered PSP is absorbed in the gastrointestinal tract.
The mushroom’s active compounds are readily absorbed in the gut, allowing them to exert their beneficial effects on the body and brain.

What Are the Cognitive and Neurological Benefits of the Turkey Tail Mushroom?
Turkey Tail provides several brain-boosting benefits:
Benefit | Mechanism |
---|---|
Neuroprotection | PSK and PSP protect neurons from oxidative stress and inflammation, which can lead to cognitive decline. |
Neurogenesis | Turkey Tail stimulates the growth of new brain cells, especially in the hippocampus – the memory and learning center. Increased BDNF levels from PSP promote neurogenesis. |
Enhanced memory and learning | By reducing neuroinflammation and supporting neurogenesis, Turkey Tail improves memory formation, retention, and recall. Animal studies show PSK and PSP enhance performance on memory tasks. |
Mood and stress regulation | Turkey Tail’s anti-inflammatory effects may alleviate depression and anxiety. PSP modulates cytokines involved in mood disorders. |
How Does Turkey Tail Enhance Learning and Memory?
Turkey tail mushroom enhances learning and memory through several mechanisms.
According to a study by Food & Function, polysaccharide-K (PSK), a key compound in Turkey Tail, improved spatial memory and learning in mice by reducing oxidative stress and inflammation in the brain.(1)
PSK also increased the expression of brain-derived neurotrophic factor (BDNF), a protein crucial for synaptic plasticity, learning, and memory.
Additionally, Turkey Tail contains antioxidants like flavonoids and phenols that protect neurons from damage caused by free radicals.
A study from 2020 found that Turkey Tail extract exhibited strong antioxidant activity, scavenging up to 94.7% of free radicals in vitro.(2)
Key benefits for learning and memory:
- Reduces oxidative stress and inflammation
- Increases BDNF expression
- Protects neurons from free radical damage
How Does Turkey Tail Support Mood Regulation?
Turkey Tail mushroom supports mood regulation by modulating neurotransmitter levels and reducing inflammation in the brain.
PSK has been shown to increase serotonin and dopamine levels, neurotransmitters associated with positive mood and reduced anxiety.(3)
Moreover, Turkey Tail’s anti-inflammatory properties help alleviate symptoms of depression.
Inflammation in the brain has been linked to the development of depression, and Turkey Tail extract significantly reduced pro-inflammatory cytokines in mice subjected to chronic stress.(4)
Mood regulation benefits:
- Increases serotonin and dopamine levels
- Reduces inflammation linked to depression
- May alleviate symptoms of anxiety and depression
How Does Turkey Tail Contribute to Neurogenesis?
Turkey Tail mushroom promotes neurogenesis, the growth and development of new neurons, by stimulating the production of neurotrophic factors like BDNF and nerve growth factor (NGF).
PSK may increase the expression of BDNF and NGF in the hippocampus, leading to enhanced neurogenesis and improved cognitive function.
Furthermore, Turkey Tail’s antioxidant and anti-inflammatory properties create a favorable environment for neurogenesis by reducing oxidative stress and inflammation that can impair the growth of new neurons.(5)
Neurogenesis benefits:
- Stimulates production of BDNF and NGF
- Enhances growth of new neurons
- Creates favorable environment for neurogenesis
How Does Turkey Tail Enhance Neuroprotection?
Turkey Tail mushroom provides neuroprotection by shielding neurons from various stressors, including oxidative damage, inflammation, and toxins.
The antioxidants in Turkey Tail, flavonoids and phenols, neutralize free radicals that can cause cellular damage and contribute to neurodegenerative diseases like Alzheimer’s and Parkinson’s.(6)
A study by Neuroscience Bulletin found that PSK improved cognitive function and reduced beta-amyloid levels in a mouse model of Alzheimer’s.(7)
Neuroprotection benefits:
- Shields neurons from oxidative damage and toxins
- Reduces inflammation in the brain
- May prevent the accumulation of beta-amyloid plaques

What Are The Side Effects and Risks of Taking Turkey Tail Mushroom?
Turkey Tail is well-tolerated, with few reported side effects.
However, some people may experience mild digestive discomfort, such as bloating or gas, when first taking the mushroom.
In rare cases, allergic reactions may occur, particularly in those with mushroom allergies.
Who Should Avoid Turkey Tail Mushroom?
While Turkey Tail is safe for most people, certain individuals should exercise caution:
- Pregnant and breastfeeding women, due to limited safety data
- Those with autoimmune disorders; Turkey Tail may stimulate the immune system
- People with mushroom allergies or sensitivities
Does Turkey Tail Mushroom Interact With Any Medications?
Turkey Tail may interact with immunosuppressant medications, as the mushroom can enhance immune function.
Those taking blood thinners should also consult their healthcare provider before using Turkey Tail, as the mushroom contains compounds that may affect blood clotting.
What Are the Uses of Turkey Tail Mushroom?
Turkey Tail mushroom (Trametes versicolor) is a popular medicinal mushroom with a variety of applications and uses, such as:
- Immune System Support: Turkey Tail is known for its immune-boosting properties. It contains polysaccharopeptides (PSK) and polysaccharide peptides (PSP), which help stimulate and regulate the immune system.
- Cancer Support: PSK and PSP found in Turkey Tail are used as complementary therapies in cancer treatment. They have been shown to enhance the efficacy of conventional treatments like chemotherapy and radiation by boosting the immune system and potentially inhibiting tumor growth.
- Gut Health: Turkey Tail contains prebiotics that support gut health by promoting the growth of beneficial bacteria in the digestive tract.
