Four Leaf Rover Turkey Tail is a certified organic single-mushroom extract containing the highest beta-glucan content of any medicinal mushroom — guaranteed minimum 50% beta-glucans per batch. Made from 100% organic turkey tail fruiting bodies grown on natural wood substrates in greenhouses with filtered air, double extracted and triple-tested for purity, potency, heavy metals and pesticides.
Turkey tail contains two uniquely potent beta-glucans — PSK (Polysaccharide-K) and PSP (Polysaccharide Peptide) — that help support immune function and microbiome balance. It also has prebiotic properties that promote a healthy balance of gut bacteria, further supporting immune health from the inside out. The highest-potency focused mushroom supplement for dogs needing targeted immune support. No grains, no fillers, no starch. Made in the USA.

Ingredient & What Makes It Different
Ingredient: 100% Certified Organic Turkey Tail Mushroom Extract (Trametes versicolor) — whole fruiting body, grown on natural wood substrates in filtered-air greenhouses.
Key compounds:
- PSK (Polysaccharide-K) — a beta-D-glucan that binds directly to immune cell receptors, activating macrophages and NK cells. PSK is the main compound in an anti-cancer drug approved in Japan called Krestin
- PSP (Polysaccharide Peptide) — works alongside PSK to enhance immune response and support overall immune resilience
- Ergosterol — found in all mushrooms; provides antioxidant and immune-supporting properties
- Prebiotic compounds — promote a healthy balance of beneficial gut bacteria, supporting microbiome and immune wellness
Why fruiting bodies matter:
Beta-glucans from the mushroom fruiting body are more bioavailable and potent than those from grain-grown mycelium. Real mushrooms contain less than 5% starch — mycelium on grain is mainly starch with far fewer active compounds. Turkey Tail has the highest beta-glucan content of any mushroom — 50% guaranteed per batch.
Triple-tested for safety:
Mushrooms are grown on wood in filtered air in greenhouses, then tested for pesticides and heavy metals before leaving the farm, tested again on arrival in the USA, and tested a third time before being put into jars.
Feeding Guide
Give orally daily or as directed by your veterinarian. Can be mixed into your dog's meals. Safe for consistent daily long-term use for dogs of all ages.
Frequently Asked Questions
What is turkey tail mushroom?
Turkey tail is a cloud-shaped mushroom found globally that grows on dead wood. Unlike most mushrooms that grow only in warmer seasons, turkey tail can survive and thrive in both hot and cold temperatures year-round. It has the highest immune-supporting beta-glucan content of any mushroom.
Why would I choose Turkey Tail instead of Seven Shrooms?
Turkey Tail is a focused, high-potency single mushroom best suited for dogs needing targeted, concentrated immune support — particularly dogs with immune challenges. Seven Shrooms provides broader synergistic support across multiple body systems. The two can also be used together for comprehensive immune and whole-body wellness.
How is this different from lower-quality mushroom powders?
Many mushroom products use grain-grown mycelium — which is mainly starch with low beta-glucan content. Turkey Tail uses only 100% organic fruiting bodies grown on wood, with guaranteed minimum 50% beta-glucans and triple-tested for purity. The FDA states mycelium-on-grain products cannot technically be called mushrooms.
Can Turkey Tail support gut health?
Yes — turkey tail has prebiotic properties that help promote a healthy balance of beneficial gut bacteria, which further supports immune function.
Is Turkey Tail safe for daily long-term use?
Yes — gentle enough for consistent daily use as part of a long-term wellness routine for dogs of all ages, including seniors.
Is this suitable for cats?
Some pet owners use medicinal mushrooms for cats, but feeding requirements differ. Always consult your veterinarian before use.
