Immunity Organic Mushroom Mix

Rated 5.0 out of 5 stars
3 Reviews



While other mushrooms 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.


Turkey Tail, Chaga, Cordyceps, Phellinus, Maitake Mushroom Extract, Reishi Mushroom Extract, Shiitake Mushroom Extract. No preservatives, fillers, binders or flavorings.

Turkey Tail

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.


There's a lot of research in Korea showing Phellinus is a potent immune modulating mushroom. It can stimulate the immune system and protect against illness.

Directions For Use

If your dog doesn't have any health challenges, once a day should be enough. But if your dog is fighting an illness,  you can give mushrooms twice daily.

    Mushrooms Work!

    The mast tumor on our 9# yorkiepoo’s face has been very worrisome. We started her on mushroom drops (4 weeks ago) and then added the turkey tail mushroom powder. The combination routine is working quite well in reducing the tumor size and pup discomfort! Impressive holistic therapy! Guess our bet and the chemo doc will have to wait a bit longer for their new sports cars!

    Great stuff

    I’ve been wanting to try this from Four Leaf Rover. It was just slightly cheaper than at Dogs Naturally. My dog doesn’t have cancer but I would like to boost his immune system as he is middle aged. He always has post nasal issues and the turkey tail helps with that. Love that this product is the whole mushroom grown on wood and not just the mycelium like so many other products 😁.
