Seven Shrooms

Not all mushrooms for dogs are created equal.

Seven Shrooms is a premium mushroom supplement for dogs, crafted with a synergistic blend of seven powerful mushroom species to naturally support immune and organ health.

• High in Beta-Glucans: Unlike many products that rely on mycelium, we use the entire mushroom—including the fruiting body—and rigorously third-party test every batch to ensure high levels of immune-supporting beta-glucans.
• Water Extracted for Potency: Hot water extraction gently releases beta-glucans from mushrooms’ tough cell walls, helping preserve these valuable polysaccharides in a concentrated, usable form.
• Grown Naturally: While others grow mycelium on grain, our mushrooms are cultivated on real wood in pesticide-free greenhouses, just as nature intended.
• Veterinarian Formulated: Each mushroom is carefully selected for its targeted support of the gut, liver, kidneys, and immune system.

How to Spot Real Mushrooms Powder for Dogs:

The FDA requires products labeled “mushroom” to contain meaningful beta-glucan content, and Seven Shrooms delivers. Here's the verified beta-glucan content in each of our seven mushrooms:

• Turkey Tail: 53%
• Reishi: 47%
• Cordyceps: 27%
• Maitake: 36%
• Phellinus: 23%
• Shiitake: 32%

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 hot water extract our mushrooms. 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.
