What Can Functional Mushrooms Do for Your Pets?
Our pets are part of the family, and supporting their everyday wellness means helping them stay healthy throughout every stage of life. Functional mushrooms offer a unique way to complement that daily commitment by helping to support things like their immune function, cellular health, and overall well-being.
Now, Host Defense® is bringing decades of mycological expertise to your pets with Immune & Whole-Body Support, our new functional mushroom supplement formulated specifically for dogs and cats.
This easy-to-use daily powder combines certified organic mushroom mycelium from five species—Lion’s Mane, Reishi, Turkey Tail, Chaga, and Maitake—to support daily immune and whole-body wellness for dogs and cats.
From morning walks and afternoon naps to all the moments in between, daily wellness is built on the little things we do consistently. Adding functional mushrooms to your pet’s routine can be one more way to show them you care by supporting their overall health and vitality as they move through life by your side.
How Can Functional Mushrooms Support Pet Wellness?
Functional mushrooms contain a diverse range of naturally occurring compounds that can help support important functions throughout your pet’s body.
Immune & Whole-Body Support is a functional mushroom supplement developed specifically for dogs and cats to help them live their best lives. Whether you’re looking for immune support for dogs and cats or a way to complement your pet’s everyday wellness routine, the formula offers support in three key areas.
Instead of focusing on just one aspect of wellness, the formula takes a whole-body approach. That means supporting some of the foundational functions that help your pet stay at their best—from a healthy immune response to cellular health and everyday vitality.
Balanced Immune Response
A healthy immune system is an important part of everyday wellness. Immune & Whole-Body Support helps maintain a balanced immune response and supports normal immune function for pets.
Your pet interacts with a changing environment every day, whether they’re exploring the backyard, joining you on a walk, meeting new friends, or simply settling into their favorite spot at home. Immune system support for cats and dogs is all about promoting immune health in a way that lays a foundation for their everyday health and resilience.
Cellular Health and Antioxidant Activity
Healthy cells help support whole-body vitality. This five-mushroom formula supports healthy cellular function and antioxidant activity throughout different stages of your pet’s life.
Cellular health is foundational to wellness throughout your pet’s body, making it an important consideration at any age. Supporting these fundamental processes with functional mushrooms is one way Immune & Whole-Body Support takes a broader approach to your pet’s everyday well-being.
Whole-Body Wellness
Taking a whole-body approach to wellness, the formula's five mushroom species work cooperatively to offer comprehensive support for your pet’s everyday health and overall well-being.
That approach makes the formula easy to incorporate into a consistent wellness routine for your best friend rather than waiting for a particular occasion to think about your pet’s health. From younger pets beginning their journey to longtime companions enjoying their golden years, everyday support can be part of caring for them throughout life.
Five Functional Mushrooms, One Daily Formula
Featuring USA-grown mushroom mycelium from five species, the blend was designed with synergy in mind to specifically support the everyday wellness of your pets.
The species include:
- Lion’s Mane
- Reishi
- Turkey Tail
- Chaga
- Maitake
At Host Defense®, we understand that mushrooms have different characteristics and naturally occurring compounds. Bringing multiple mushroom species together allows us to create a more comprehensive formula rather than relying on a single species for your pet’s everyday wellness.
The result is one convenient blend that makes it simple to incorporate five functional mushrooms into your pet’s daily routine.
USA-Grown Mushroom Mycelium, Now for Pets
Mushroom mycelium is the primary living stage of the fungal life cycle, representing 95% of the mushroom lifespan. Backed by 40+ years of scientific research, Host Defense® specializes in functional mushroom supplements that use mushroom mycelium as their foundation.
Immune & Whole-Body Support incorporates mushroom mycelium cultivated on our certified organic farm in Washington state. Growing our own mushroom mycelium gives us greater oversight over the cultivation process and affirms our commitment to ingredient quality and sourcing transparency.
For pet parents, knowing what goes into a supplement is important—but knowing where those ingredients come from matters, too. Our approach allows us to remain closely connected to our mushrooms from cultivation onward rather than relying on mushroom ingredients grown by unknown suppliers.
Everyday Wellness Through Every Stage of Life
Immune & Whole-Body Support is designed for dogs and cats throughout all stages of life—from playful puppies and curious kittens to longtime companions. The easy-to-use powder is intended for oral use, making it simple to incorporate the formula into their everyday routine.
Recommended amount: Administer ½ teaspoon (1 g) per 25 lbs of body weight per day.
Your pet’s day-to-day activities can look different as they grow and age. A young dog’s daily routine may be filled with seemingly endless energy and exploration, while an older cat might prefer a quiet afternoon in a sunny window. Immune & Whole-Body Support was developed as a functional mushroom supplement that offers a convenient way to support your pet’s foundational wellness throughout those different stages.
Because every pet has individual needs, we recommend speaking with your veterinarian before introducing any new supplement, particularly if you have questions related to your pet’s age, size, health history, or current wellness routine.
