Four Leaf Rover Seven Shrooms



While other mushroom products are mycelium (a lab-grown fungus that's only part of a mushroom), Four Leaf Rover Immunity contains the fruiting body and the mycelium.

Mycelium is grown on grains like oats, sorghum or rice, not on wood where mushrooms would grow in nature. Mycelium products contain significantly lower levels of valuable beta-glucan, the active medicinal compound in mushrooms. Your dog deserves Four Leaf Rover's REAL mushrooms ... grown the way nature intended and complete with all their health-boosting properties. 

  • Organic
  • Not Mycelium

Turkey Tail

Turkey Tail

Turkey tail is a mushroom that grows on dead logs all around the world. Its Latin name is Trametes versicolor or Coriolus versicolor. Versicolor means of many colors. And that’s because Turkey Tail has colored rings that look a lot like the tail of a turkey. In Japan, Turkey Tail is called kawaratake, which means cloud mushroom. There are quite a few strains of Trametes, but Turkey Tail in particular is of interest to scientists and herbalists. Turkey Tail has been used in Chinese medicine for centuries to reduce phlegm, clear dampness, increase energy and boost the immune system. In traditional Chinese medicine, it’s called Yun Zhi.



Chaga grows naturally on birch trees. That's why we grow our Chaga mushrooms sustainably, on native materials. Research suggests Chaga may be able to help regulate and boost the production of cytokines. Cytokines are essential to the immune system ... and a good immune system can help fight off infection and disease.



Cordyceps are full of antioxidants. Cordyceps are known to help boost physical performance and may support a healthy heart.



Korea has done allot of research showing Phellinus is a potent immune modulating mushroom. It is used to stimulate the immune system and protect against illness. 

Frequently Asked Questions

Mushrooms contain a fruiting body (the part of the mushroom you'd recognize) and mycelium, the part that grows underground or inside the plant. Think of the mycelium as the roots of the mushroom. Nearly all mushroom products are mycelium, not the actual mushroom. They're grown in a lab on sterilized grains (such as rice, sorghum or oats) and ground into a powder. If you're buying a mycelium product, you're not getting the beta-glucan rich content of the fruiting body. Beta-gulcans are the active compounds in mushrooms. Fruiting bodies are full spectrum and also offer more vitamins and minerals. You're not getting a real mushroom and your dog is not getting all of the health benefits.

Our mushrooms are grown on wood, just as they would in nature. This guarantees the medicinal compounds will be in the mushrooms. They're grown in greenhouses with a constant flow of fresh air and water, along with natural sunlight. After harvesting, every mushroom is tested for chemicals or contamination.

Fruiting bodies require hot water extraction to break down the chitin in the cell walls. Dogs and humans lack the enzyme to do this, so extraction is necessary to get all the nutrients from the fruiting body. Extraction pulls out the beta-glucans. The extraction is then purified and dried into a powder with all the beneficial mushroom parts intact.

Immunity 7 mushroom blend does contain Turkey Tail mushroom, but you can still add Turkey Tail once or twice daily for additional immune benefits.

If your dog doesn't currently face any health challenges, once per day should be enough to gain the benefits. But if your dog is fighting an illness, you can give mushrooms twice daily.
