Immune Support
Beta‑glucans are among the mushroom compounds most widely researched for their interaction with normal immune function.
Why functional mushrooms
Nature’s Most Powerful Wellness Compounds.
For thousands of years mushrooms have been used to support health. Modern research is now uncovering why.
From tradition to evidence
A long history. A more precise future.
Traditional use
Long valued as food and within wellbeing traditions.
Scientific discovery
Research identified beta‑glucans and other naturally occurring compounds.
Modern extraction
Purposeful processing helps concentrate and standardise key components. Our mushrooms contain standardised fruiting body extracts with ≥40% beta glucans.
Made for dogs
Clinician-led formulation turns evidence into a considered daily routine.
Meet the mushrooms
Seven species. Distinct personalities.
Each mushroom earns its place for a reason. Explore the character, compounds and everyday role of the species we use.
Everyday immune support
Turkey Tail
A fan-shaped woodland mushroom valued for its naturally occurring polysaccharides.
- Primary role
- Everyday immune support
- Worth knowing
- Its layered bands resemble the feathers of a turkey’s tail.
Cognitive wellbeing
Lion’s Mane
A distinctive cascading mushroom studied for compounds associated with nerve health.
- Primary role
- Cognitive wellbeing
- Worth knowing
- Its soft spines grow in a single shaggy cluster.
Adaptation & resilience
Reishi
A glossy, woody mushroom with a long history in East Asian wellbeing traditions.
- Primary role
- Adaptation & resilience
- Worth knowing
- Its varnished surface gives it the name “lacquered mushroom”.
Immune & everyday vitality
Shiitake
A culinary and functional mushroom containing beta-glucans and other naturally occurring nutrients.
- Primary role
- Immune & everyday vitality
- Worth knowing
- Shiitake has been cultivated for more than a thousand years.
Energy & active living
Cordyceps
A distinctive functional fungus traditionally associated with energy and stamina.
- Primary role
- Energy & active living
- Worth knowing
- Modern cultivation makes consistent, animal-free ingredients possible.
Metabolic & immune support
Maitake
A clustered mushroom whose name translates to “dancing mushroom”.
- Primary role
- Metabolic & immune support
- Worth knowing
- Its overlapping fronds can grow into impressive woodland clusters.
Antioxidant support
Chaga
A slow-growing forest fungus rich in naturally occurring pigment compounds.
- Primary role
- Antioxidant support
- Worth knowing
- Chaga commonly grows on birch trees in cool northern forests.
Research & evidence
Read beyond the label.
Research is always evolving. These publications offer useful context—not promises about an individual dog or product.
Beta-glucans and canine immune parameters
A 2024 controlled feeding study compared different beta-glucan structures and measured immune and inflammatory markers in healthy dogs.
The study reported changes in selected immune parameters and emphasised that different beta-glucan structures may act through different pathways. More mechanistic research is needed.
Beta-glucans, microbiome and digestibility
A 2024 study explored increasing beta-glucan inclusion levels in healthy adult dogs.
Researchers assessed digestibility, faecal microbiota and several immune variables. It offers useful context for canine nutrition, while not testing Truffle Hound products.
Fruiting bodies and beta-glucan content
A comparative analysis measured beta-glucan levels across shiitake fruiting body sections and mycelia.
The study found variation by cultivar and reported higher beta-glucan levels in fruiting body sections than in mycelia in the samples tested.
Frequently asked questions
Clear answers, thoughtfully given.
Are mushrooms safe?
Functional mushrooms such as Reishi, and Turkey Tail have a long history of use. They are generally extremely well-tolerated when used as directed.
As with any supplement speak with your vet first if your dog has a health condition or is pregnant or nursing.
Can they be taken every day?
Mushrooms, in fact,work best when they are taken consistently over a period of time.
They are designed for daily use at the recommended serving. Follow product directions and introduce gradually for sensitive dogs.
How long before I notice benefits?
Digestive support: some dogs may show changes within a few days to 2–3 weeks.
General wellbeing/immune support: benefits are often more subtle and may take several weeks of consistent use.
Joint support: typically allow 4–8 weeks of daily use before judging the effect.
Long-term support: these products are best thought of as part of a daily wellness routine, rather than something that produces an immediate effect.
Can puppies take them?
Puppies are still developing, and there’s less research on supplementation in young dogs than in adult dogs.
Functional mushrooms can be suitable for puppies once they are fully weaned, but puppies have different nutritional needs from adult dogs. We recommend checking with your vet before introducing supplements, particularly for very young puppies or puppies with health conditions.
Can they be taken with medication?
Potential interactions depend on the mushroom, dose and medicine. Ask your vet before combining supplements with prescription medication, especially immune-modifying or anticoagulant medicines.
