They’re Real & They’re Magnificent!

Discover the true power of mushrooms with Seven 'Shrooms, a premium blend specifically crafted for your dog’s well-being.

  • High in Beta-Glucans: We use the entire mushroom, including the fruiting body, and rigorously test each batch to ensure a high concentration of immune-supporting beta-glucans.
  • Double Extracted: Our organic mushrooms are double extracted to make beta-glucans and triterpenoids highly bioavailable for optimal support of your dog’s immune system.
  • Grown Naturally: Unlike many products that use only mycelium grown on grains, our mushrooms are cultivated on real wood in greenhouses, free from synthetic fertilizers and pesticides.
  • Veterinarian Formulated: Each mushroom is chosen for its synergistic effects on the gut, liver, kidneys, and immune system.

  • Cordyceps: 27%
  • Maitake: 36%

How do you choose mushrooms for your dog?

Look for mushrooms with the highest beta-glucan content - that's the active ingredient you need. Some mushroom species naturally contain less beta-glucan content than others and may have other immune-boosting benefits like terpenes, antioxidants and polysaccharides. You also want to look for a blend of different mushrooms ... when they’re combined they work synergistically. And don't forget - real, whole mushroom products carry the best benefits.

What is Mycelium?

Mycelium is essentially the “roots” of the mushroom. Mycelium "mushroom" products are cheap to grow because there's very little mushroom and a lot of starch like oats or sorghum. Whole mushrooms are a better choice because:

1. Real mushrooms contain more beta-gluten

2. Real mushrooms are naturally low in starch

3. Our mushrooms are grown on wood, not grains, so your dog will also benefit from the soil-based goodness and minerals.

Does Seven 'Shrooms contain the fruiting body?

Of course! Seven 'Shrooms contains every part of the mushroom, including the fruiting body. The mushrooms are double extracted so your dog gets the most benefit from them. 

What is the beta-glucan content of Seven 'Shrooms?

A whole jar of Seven 'Shrooms averages 34.6% beta-glucans.

Beta-glucans are the active, immune-stimulating compound found in mushrooms. Each mushroom has varying amounts of naturally occurring beta-glucans, but we 3rd party test our mushrooms to make sure they have the highest beta-glucan content.

Here’s the total beta-glucan content of each mushroom in Seven 'Shrooms:

• Chaga - 16%
• Cordyceps - 8%
• Maitake - 15%
• Phellinus - 23%
• Reishi - 47%
• Shiitake - 32%
• Turkey Tail - 53%

Turkey Tail contains more immune-boosting beta-glucans than any other mushroom. That’s why we recommend Turkey Tail and Seven 'Shrooms be given together for dogs with significant immune challenges.

Can't I just give my dog mushrooms from the grocery store?

Yes … but with a few qualifiers. Mushrooms from the grocery store are nutritious but they're not high in beta-glucans. If you give your dog grocery store mushrooms, always give them cooked. Raw mushrooms can cause significant digestive upset in dogs. 

Are your mushrooms raw?

The beneficial parts of the mushrooms are “locked” in the chitin cell walls of the mushroom’s fruiting body which makes it hard for dogs and people to process. That’s why we double extract our mushrooms. First, they’re extracted with alcohol and then with water. Don’t worry, they’re not high in alcohol, it gets steamed out. This is the way mushrooms have been processed in Traditional Chinese Medicine for thousands of years.

Where are your mushrooms grown?

Our mushrooms are grown on wood, the way nature intended. We source our mushrooms from China, which is the only place you can source the entire mushroom. They’re grown in the mountains 300 miles from the closest city and with filtered air. They are tested for pesticides and heavy metals before they even leave China and again once they arrive in the US. 

What's the difference between Seven 'Shrooms and Turkey Tail?

Seven 'Shrooms is an organic blend of 7 types of mushrooms that are researched for their benefits and work synergistically. They have high beta-glucan content and other immune-enhancing properties. For dogs with severe immune challenges, Turkey Tail is the ideal addition to Seven 'Shrooms. Research* in dogs shows that the polysaccharides in turkey tail extended survival time in dogs with hemangiosarcoma without additional treatment.

    Good

    My Anatolian Shepherd is only on his second jar and still within the recommended twice daily dose.

    I bought for his immune system and thus have recognized better coat, clearer eyes and happier attitude.

    I've been using this along with Hip and Joint. I'm most certainly very happy with products.

    Shrooms

    Seven shoots along with Bovine Colostrum have alleviated Rosie's and Mokie's gut problems and allergies. They no longer chee the grass and throw nor are they scratching like they were.

    Seven Shrooms

    My dog was diagnosed with chronic liver disease. I feel that the Seven Shrooms helped him live longer than we had expected. He just recently has passed away. The photo here is of him a few days before his passing. His name was Newman 💔
