Seven 'Shrooms

Seven 'Shrooms is a veterinarian-formulated organic mushroom blend for dogs — seven medicinal mushroom species, all grown on natural wood substrate, all made from fruiting bodies, all double-extracted for full-spectrum bioavailability. It's the Four Leaf Rover mushroom formula for dogs whose owners want broad, whole-body support in a single daily supplement rather than stacking multiple single-mushroom products.

The blend includes Turkey Tail, Reishi, Cordyceps, Maitake, Shiitake, Chaga, and Phellinus — chosen not just for their individual benefits but for how they work synergistically across the immune system, gut, liver, kidneys, and beyond. Third-party tested per species for guaranteed beta-glucan content. Available in 51g.

Each medicinal mushroom has its own compound profile and its own area of action. Turkey Tail specialises in immune modulation and gut support. Reishi is calming and supports liver function. Cordyceps supports stamina and respiratory function. Maitake supports blood sugar balance and immune response. The list continues. No single mushroom covers everything — but combined thoughtfully, a blend of seven can.

Mushrooms also work synergistically: their active compounds complement and amplify one another rather than overlap. This is why traditional medicine systems — from Chinese medicine to Japanese and Korean herbal traditions — have used multi-mushroom formulas for centuries. Seven 'Shrooms brings this synergistic approach into a modern, tested, veterinarian-formulated supplement.

Most mushroom supplements on the market are not really mushrooms. They're mycelium — the root-like structure of the fungus — grown in plastic bags of oats, sorghum, or rice, then ground up together with the grain. The result is a powder that is mostly starch, with minimal actual mushroom content. Beta-glucan levels in these products are typically low because the active compounds live primarily in the mushroom's fruiting body, not the mycelium.

Every mushroom in Seven 'Shrooms is made from the whole, mature fruiting body — grown naturally on wood in filtered-air greenhouses. No grain substrate. No hidden starch. Just seven concentrated mushrooms. Each species is third-party tested for beta-glucan content before being combined into the final blend.

Each of the seven mushrooms in the blend is individually double-extracted — water extraction to capture beta-glucans, alcohol extraction to capture triterpenes and other alcohol-soluble compounds — before being combined. A single extraction method only captures half the active compound profile. Double extraction ensures the full spectrum of each mushroom's benefit is bioavailable to your dog.

Turkey Tail (Trametes versicolor) — 53% beta-glucans. The most research-backed immune mushroom. Contains polysaccharide-K (PSK) and polysaccharide peptide (PSP) — compounds that modulate immune function and support gut microbiome balance. Also has prebiotic properties.

Reishi (Ganoderma lucidum) — 47% beta-glucans. Known in traditional Chinese medicine as the "mushroom of immortality." Adaptogenic — helps the body manage stress. Rich in triterpenes that support liver function, cardiovascular health, and calm behaviour. One of the most versatile immune supporters.

Cordyceps (Cordyceps militaris) — 27% beta-glucans. Traditionally used for stamina, energy, and respiratory function. Supports the body's production of ATP — the cellular energy currency — making it particularly valuable for active dogs, senior dogs, and dogs recovering from illness. Also supports kidney function.

Maitake (Grifola frondosa) — 36% beta-glucans. Well-researched for its immune-enhancing beta-glucans. Supports healthy blood sugar levels and a normal inflammatory response. Particularly valuable as part of a metabolic support strategy.

Shiitake (Lentinula edodes) — 32% beta-glucans. Contains lentinan, a beta-glucan researched for its immune-activating properties. Can support gut repair and help activate immune cells. Traditionally used for dogs that are sick, stressed, or immunocompromised.

Chaga (Inonotus obliquus) — 16% beta-glucans. Lower in beta-glucans than other species, but exceptionally high in antioxidants. Supports a balanced inflammatory response, healthy heart function, and stable blood sugar levels. Nutrient-dense with a full spectrum of vitamins and minerals.

Phellinus (Phellinus linteus) — 23% beta-glucans. A potent immune-supporting mushroom used extensively in Korean traditional medicine. Supports normal detoxification processes and complements the immune-modulating actions of Turkey Tail and Reishi.

Balanced immune function. Not a stimulant and not a suppressant — a modulator. Seven 'Shrooms helps the immune system respond appropriately to threats without overreacting, which is particularly valuable for dogs with allergies, autoimmune tendencies, or chronic low-grade inflammation.

Organ health across the body. Each mushroom contributes to a different area — gut (Turkey Tail, Shiitake), liver (Reishi, Chaga), kidneys (Cordyceps, Phellinus), cardiovascular (Reishi, Chaga), respiratory (Cordyceps). Together they deliver organ support that a single-mushroom product can't match.

Cellular and antioxidant support. Chaga and Reishi are among the most antioxidant-dense whole foods available. They help combat oxidative stress — the cellular wear and tear that drives ageing and chronic disease.

Stress resilience and adaptogenic support. Reishi and Cordyceps are classic adaptogens — they help the body maintain balance under stress, whether physical (illness, exertion) or emotional (anxiety, change).

Long-term wellbeing for dogs of all ages. Because Seven 'Shrooms works across so many systems, it's suitable as a daily maintenance supplement for healthy dogs as well as targeted support for dogs with specific health challenges.

Seven 'Shrooms is the Four Leaf Rover mushroom choice when you want comprehensive coverage in a single jar rather than stacking multiple single-mushroom products. It's particularly well-suited to dogs of all ages as a daily foundation supplement, senior dogs needing whole-body support, dogs with multiple health concerns, and owners who want the benefits of a varied medicinal mushroom diet without managing several products. For targeted high-potency single-mushroom support, Turkey Tail delivers the highest beta-glucan content in the range. For cognitive and nervous system support specifically, Lion's Mane — which Seven 'Shrooms does not include — is the specialist.

Every batch of Seven 'Shrooms is third-party tested for beta-glucan content per species, pesticides, heavy metals, and microbial contaminants, with a Certificate of Analysis available on request. Four Leaf Rover holds the NASC Quality Seal — the benchmark for quality control in the pet supplement industry — and is certified Plastic Negative by rePurpose Global, removing twice the plastic from the environment that it creates. Manufacturing is GMP-compliant.
