Supplement Breakdown and Information

Immunity Blend - Organic Mushroom Mix

 The demand for mushrooms is growing. People are aware of their ability to support the immune system, making Immunity one of our most requested products.

The mushrooms in Immunity have been hand-picked to help support your dog’s immune system. Our double extraction process makes sure that the beneficial beta-glucans and triterpenoids are bioavailable and ready to help balance your dog’s immune system.

You can expect high-quality from Immunity because all of our mushrooms are grown on real wood in greenhouses.

This is not a common practise, as one might think. Most mushroom products are mycelium and grown in bags of oats, sorghum or other grains.

This process is cheaper for the manufacturers and the whole mushroom (which is the source of  beta-glucans and other active ingredients) is never actually used. This results in a “mushroom” product that lacks highly rich components your dog deserves.

Even though the FDA doesn’t allow mycelium products to call themselves “mushrooms” on their labels (because its lacking key properties), it still happens.

Manufactuerers get around this by adding trace amounts of the fruiting body just so they can call their product mushroom.

So how can you tell the difference between real mushrooms and the other guy (mycelium)?

Simply look or ask for the beta-glucan content.

You can feel good about giving your dog Immunity. It is third party tested for beta-glucan content so your dog gets the mushroom qualities he needs:

Our Beta-Glucan Content Breakdown:

Turkey Tail - 53%
Reishi - 47%
Cordyceps - 27%
Maitake - 36%
Phellinus - 23%
Shiitake - 32%
Chaga - 16%

Immunity is a veterinary formulated blend of seven organic mushrooms:

Turkey Tail
Turkey Tail is known for its immune balancing benefits thanks to two important immune modulating beta-glucans: PSK & PSP. Plus, Turkey Tail can support liver function and gut health.


Chaga’s rich beta-glucan content can help support the heart, intestine and liver health. It’s also loaded with polyphenols which are plant-based antioxidants that can diminish free radical damage.


Cordyceps is a multi-functioning mushroom that’s been known to help support the airways, the liver and kidneys. Cordyceps is stocked full of polysaccharides that help a protein called cytokines enable the growth of healthy blood cells. This helps the body’s immune and inflammatory response.


Phellinus is a potent mushroom rich in beta-glucans and proteoglycns (PGs). Research shows its rich immune-boosting functions can help support cell health and a normal detox processes in the body.


Maitake is, yet another mushroom with exceptional immune enhancing content. It’s loaded with beta-glucans and D-fraction, that’s been researched as a powerful immune booster.


Reishi is known as the “mushroom of immortality”, and so it should be! Its anti-inflammatory and antihistamine qualities stem from rich sources of antioxidants, ganoderic acid and triterpenoids that come straight from the mushroom itself.


Shiitake’s not just fun to say, but it’s been shown to support the gut in digestion, allergy response and urinary health. This mushroom is stocked with beta-glucans, lentinan (which can support immunity and the heart), and enzymes like amino acids, amylase and minerals (zinc).

Green Eggs: Natural Joint Support - promotes long-term health by supporting joint mobility, healthy skin and more.

Green Eggs includes glycosaminoglycans (GAGs) like chondroitin sulfate and hyaluronic acid. It also has anti-inflammatory fatty acids and collagen. 

Green Eggs can help

  • Promote good joint health
  • Prevent inflammation
  • Support cartilage protection
  • With sports recovery
  • With senior support 

Green Eggs is the natural approach to joint support. Its four simple but powerful ingredients with proven results.

Ingredient Breakdown:

1. Green Lipped Mussels

There are studies being done on Green Lipped Mussel as an alternative for dogs that can’t tolerate the side effects from NSAIDs (non steroidal anti-inflammatory drugs).

NSAIDs and Green Lipped Mussels are COX (cyclooxygenase) inhibitors. COX enzymes are responsible for initiating inflammation by irritating immune chemicals called prostaglandins.

Green Lipped Mussels (GLM) house glycosaminoglycans (or GAGs), which includes chondroitin sulfate. Chondroitin helps build and strengthen joint cartilage.

There are also a good source of anti-inflammatory fats in GLM, including EPA and ETA. The mussels in Four Leaf Rover have fats with an average 6-10% content.

In a 2007 study, dogs were given Green Lipped Mussel for 8 weeks. They had a significant improvement in pain and mobility. And most of the dogs didn’t need pain meds.

In a study back in 2007, dogs were given Green Lipped Mussel for 8 weeks. After those weeks, researchers observed big improvements in their pain and mobility. Most of the dogs no didn’t require any pain drugs.

Our Green Lipped Mussels are farmed sustainably in clean waters of New Zealand. They are responsibly freeze-dried, a great source of vitamins and minerals and high bioavailable. (See Research Below FAQs)

2. NEM® Eggshell Membrane

NEM® is also rich in glycosaminoglycans (GAGs) including chondroitin sulfate, hyaluronic acid and collagen.

In a 2017 randomized trial, it showed NEM® decreased activity-related joint pain in only 8 days. In other clinical trials pain was shown to decrease in 7 - 10 days.

In addition, NEM® has clinically been proven to help protect joint cartilage.

NEM® comes from healthy human-grade eggs that are typically used for baking foods. Often other eggshell membranes come from thrown out, potentially unhealthy eggs. (See Research Below)

3. Poria Cocos

Poria has been around for thousands of years and used in Traditional Chinese Medicine.

Poira grows on the roots of trees and not necessarily on the mushroom, it’s a mass of mycelium. It's typically not very high in starch (less than 5%) and abundant in immune-supporting beta-glucans.

Four Leaf Rover's Poria is a minimum 30% beta-glucan.

Poria is used for inflammation, but specifically great for swelling and edema that can often occur on ears and paws. It’s also a good support of skin issues too.

Poira mushrooms are 100% organic and grown on trees.

4. Curcumin

Curcumin is the potent substance in turmeric that everyone loves. It helps promote a good inflammatory response and can support joint health.

To make sure that the Curcumin in Green Eggs is high-quality and highly concentrated, it is carbon-14 tested to make sure it houses at least 95% curcuminoids. making it a highly concentrated source of curcumin.

This testing measures the amount of carbon-14 from a sample from every batch and compares the result to the international standards.

The higher the bio-based carbon, the better we can ensure that the Curcumin is from good and natural sources.

This also makes sure that every jar is synthetic-free, which sets it apart from other products on the market today.

Bovine Liver

Liver supports the liver. And that means it can help support your dogs immune health and help keep him safe from environmental chemicals. Bovine liver is also  a good source of vitamin A which is linked to iron and hormone function.

Bovine Heart

Bovine heart has a dense source of taurine, collagen, vitamin B12 and Coenzyme Q10 (CoQ10). This helps support mitochondrial health, connective tissue and mobility.

Bovine Kidney

Bovine kidney has a good spruce of selenium, diamine, oxidase, enzymes and B12. It can help support urinary, kidney and thyroid health, the detoxification process in your dog, and support histamine levels.

Bovine Pancreas

Bovine pancreas has essential enzymes your dog requires to help break down proteins, fats and carbohydrates. This is crucial to supporting digestive and pancreas health for maximum nutrient  absorption. 

Bovine Spleen

Bovine spleen Spleen has peptides and proteins  to help support immune and digestive health. It can also help support inflammation reduction.

Bovine Adrenal

Bovine adrenal helps support the adrenals in your dog. It’s also linked to  supporting good DNA methylation, glucose levels, detox levels and energy.

Bovine Thymus

The thymus gland can help support your dog’s thymus gland. Over time it tends to shrink because it’s susceptible to toxins and oxidation.

Supporting the thymus gland with thymus can help specialized proteins, peptides and thyroxin, which can also support immune health.

Gut Guard - controls inflammation in the digestive tract. The natural prebiotics are there to help restore the good bacteria colonies.

Every ingredient in Gut Guard has been extensively researched and carefully sourced for superior quality.  It's a veterinary formulated blend of anti-inflammatory herbs that target distressed guts, plus proven performers that are researched for their  ability to heal and seal a damaged gut lining. Gut Guard also contains a proprietary blend of spore-forming bacteria that can survive the harsh conditions of the digestive tract, and Pediococcus acidilactis, which is known for its ability to support distressed guts.

Formulated By A Vet

Every ingredient in Gut Guard has been highly researched and carefully sourced by veterinarian Patricia Jordan. This safe and effective formulation is designed to help soothe and support a dogs gut.

Tough & Robust Probiotics

Gut Guards synergistic combination of prebiotics, probiotics and soothing ingredients are much more likely to survive the harsh gut environment than traditional probiotics. This makes it a powerful alternative to traditional probiotics and medications.

There’s a probiotic strain called “Pediococcus acidilactis”. It’s often found in fermented vegetables. It’s been known to survive extreme ranges of pH and temperature, which makes it a staple towards healing leaky guts.

 Dogs often struggle with itchy, rashy skin, digestive issues, inflammation disorders and kidney issues on and off their whole lives. Sometimes it’s worse, like an autoimmune disease. After plenty of vet visits and misdiagnoses, pet owners are often finding the root cause of these problems is actually Leaky Gut.

Leaky Gut is referred to as the “Great Imitator”. It’s what happens when your dog’s gut lining is inflamed, it becomes more permeable. That’s when toxins, allergens and bacteria can leak into the blood causing common allergy-like symptoms and immune disorders.

Gut Guard is a robust formula created to supply beneficial bacteria back into your dog’s body with gut-soothing herbs and foods.

The ingredients in Gut Guard have been carefully hand-picked for exceptional quality.
The synergistic blend of well-researched anti-inflammatory ingredients help towards heal and seal damaged gut lining.

Brain Food - Brain Food is the perfect choice for senior dogs or dogs needing an immune boost.

It’s a blend of three simple ingredients: New Zealand grass-fed calf brain, organic lion’s main mushroom and wild organic blueberries. 

Brain Food is a combination of ingredients that work together, synergistically to help support your dog’s brain and nervous system health.

Freeze Dried Brain

The freeze-dried brain in Brain Food comes from BSE-free New-Zealand calves. Brain is a healthy source of:

  • DHA, the omega-3 fatty acid that fuels the brain and eyes
  • Brain Derived Neurotrophic Factor (BDNF), a protein linked directly to memory, brain cell health and stress response.
  • Sphingomyelin and important proteins and peptides.

Lion’s Mane Mushroom

Lion’s Mane mushroom is called “the smart mushroom” because of its compounds that can help enhance brain function.

Studies show that Lion's Mane mushroom can grow and protect brain cells: hericenones and erinacines. 

In one study, Lion's Mane mushroom decreased loss of memory in mice* and it prevented the amyloid plaques linked to Alzheimers disease. 

*Mori et al Effects of Hericium erinaceus on amyloid β(25-35) peptide-induced learning and memory deficits in mice 2011

Wild Organic Blueberries

Blueberries are rich in anthocyanin, a powerful antioxidant that has an affinity for the brain and nervous system.

*Freeze-dried calf brain retains heat-sensitive vitamins and minerals. Other brain products are heat processed which kills off the same heat-sensitive vitamins and minerals that make brain so healthy.
