Reishi (Ganoderma lucidum) has been used for over 4,000 years in Traditional Chinese medicine, and is known as the “Mushroom of Immortality” It is one of the most versatile ingredients in our entire range. Its active compounds ( Beta-glucans, Triterpenes) work on several fronts at once. It helps the immune system respond appropriately rather than overreact. It calms the inflammation that drives joint pain and stiffness. It neutralises the cellular damage that builds up over time, and helps to stabilise the overreactions that show up as allergies, itching, and skin sensitivity in dogs.

What makes Reishi genuinely remarkable is that all of this happens simultaneously — not as separate effects, but as part of one interconnected response that helps the whole body find its balance. For dogs dealing with joint stiffness, seasonal allergies, a weakened immune system, or simply the gradual challenges of getting older, Reishi works quietly and consistently across every front. It’s the kind of ingredient that’s hard to put in a single box — which is exactly why it belongs in two of ours.

Turkey Tail (Trametes versicolor) is one of the most researched functional mushrooms, with a strong body of evidence supporting its use in dogs. Naturally rich in beta-glucans, it helps support your dog’s immune system so it can respond appropriately; stepping in when needed, without overreacting.

In practical terms, this means supporting your dog’s natural defences against things like seasonal sensitivities, environmental irritants, and everyday bugs, while also helping to keep inflammation in check.

Turkey Tail also acts as a natural prebiotic, helping to nourish beneficial gut bacteria and maintain a healthy digestive environment. This dual action, supporting both immune resilience and gut health, makes it a cornerstone ingredient in our Immune and Digestive formulas.

Shiitake Mushroom
Shiitake (Lentinula edodes) is one of the most well-researched functional mushrooms in the world; and it earns its place in both our Immune and Joint Blends.

Its key compound, lentinan, helps support a balanced and responsive immune system; meaning your dog can react appropriately when it matters most, whether that’s during recovery from illness, after injury or surgery, or when facing everyday environmental stress.

Shiitake’s benefits go even further. Its beta-glucans and natural antioxidants help regulate the inflammatory signals linked to joint stiffness, while also supporting the body’s ability to manage oxidative stress; a key factor in cartilage wear over time.

Naturally occurring copper, selenium, and B vitamins further support connective tissue and overall joint health, making Shiitake one of the most well-rounded ingredients we can put in your dog’s corner.

Cordyceps (Cordyceps militaris) has been used in Traditional Chinese and Tibetan medicine for over 1,500 years; and it brings something genuinely different to our Immune Blend.

Its standout compound, cordycepin, is unique to Cordyceps and works at a cellular level, supporting energy production, helping regulate inflammatory signals, and activating key immune cells. The result: more energy, less inflammation, better ability to recover and thrive.

Like the other mushrooms in our blend, it calibrates your dog’s immune response rather than just turning up the volume. And because it works with the body rather than forcing a reaction, it’s gentle on even the most sensitive dogs. For dogs that need a little extra support, whether due to age, stress, or recovery; it’s a quietly powerful addition.
