A blend of different mushrooms works best as they work synergistically. Next, look for the highest beta-glucan content. Beta-glucans are the active ingredient in mushrooms and your product should guarantee a large amount. Seven 'Shrooms is veterinarian formulated to provide immune support for all dogs.

Mycelium is just the “roots” of the mushroom, and doesn’t contain the whole fruiting body (which is the part that grows above ground). Mycelium doesn’t offer the same high beta-glucan content found in the fruiting body. 

Mushrooms are expensive to grow on their natural substrate (typically wood and trees). So most mushroom products are what’s called “myceliated grain.” This cheap and fast way to grow mushrooms is just mycelium grown in bags of oats, rice or other grains. This whole bag, grains and all, is sold as “mushrooms” but differs from real, whole mushrooms in two ways. First, it’s much lower in beta-glucans and second, the resulting product is mainly starchy grains (real mushrooms are less than 5% starch).

Because of these differences, the FDA states mycelium on grain products can’t be called mushrooms - but many still are. Or, they add a small amount of fruiting body to keep costs down and still claim it’s a mushroom product. 

The only way to know if your dog’s mushroom product is whole mushrooms, is to ask for the beta-glucan amount - not the polysaccharide content or alpha-glucan content, because those are found in any product with a lot of grains

Every Four Leaf Rover mushroom is grown on its natural substrate in greenhouses with filtered air - they’re grown the way nature intended. 

Yes! Seven 'Shrooms uses every part of the mushroom which includes the fruiting body. Each mushroom is double extracted. The extract is then dried into a powder with all the essential mushroom elements (triterpenoids and beta-glucans) intact. 

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

Beta-glucans are the active, immune-supporting compound found in mushrooms. Not all mushroom species are the same and carry different amounts of beta-glucans and immune supporting substances like triterpenoids. Our mushrooms are third-party tested to ensure they have a high, guaranteed beta-glucan content, while being low in pesticides and heavy metals.

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

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

Turkey Tail has the highest amount of immune-supporting beta-glucans, more than any other mushroom. For dogs needing extra support, we recommend adding Four Leaf Rover’s Turkey Tail product to Seven 'Shrooms.

You can. But, while mushrooms from the grocery store are nutritious, they lack high levels of beta-glucan. The mushrooms also have a tough outer wall that’s difficult for dogs (and humans) to break down, so double extraction is a good idea to make the beta-glucans and immune supporting compounds available. 

The mushrooms in Seven 'Shrooms are not raw, but rather double extracted. Raw mushrooms can irritate your dog’s gut, which can lead to vomiting, diarrhea and cause dehydration. The valuable part of a mushroom is “locked” in its chitin (cell wall). Dogs and people lack the enzyme required to break chitin down, so our mushrooms are double extracted to make them more bioavailable. This process releases the beneficial compounds such as beta-glucan. First, they’re extracted with alcohol and then with water. Don’t worry, they’re not high in alcohol - it’s released during the steaming process. This has been the process in Traditional Chinese Medicine for thousands of years.

Our mushrooms come from China, which, believe it or not, is the only place you can find the entire mushroom. With that said, we take safety and purity seriously. Our mushrooms are grown on wood, in filtered air, way up in the mountains, hundreds of miles from the cities. Before the mushrooms leave China, they’re tested for pesticides and heavy metals and once they arrive in the USA, they’re tested again, then tested a third time before we put them into jars.
